Microporous annealed particle scaffolds (MAPS) are a sub-class of granular hydrogel material with a void space network stabilized by inter-particle chemical bonds. The modular nature of granular hydrogels offers enormous tunability in not only the individual microgel design but also the homogenous or heterogenous microgel assembly into the bulk scaffold. This session will explore current advances in granular hydrogel technology, including MAPS, for both immune modulation, tissue repair, organ-on-a-chip, and 3D-printing applications.

Host Response to Biomaterials/Macrophage Plasticity at Tissue-Biomaterial Interface

Materials developed that are intended for human application such as biomaterials, medical devices, or prostheses evoke a multitude of biological responses when implanted into living tissue. These responses vary and include: injury, inflammation, wound healing, foreign body reactions, and fibrous encapsulation of the biomaterial, medical device, or prosthesis. Developing strategies to regulate immune responses poses a significant challenge with respect to the clinical translation of tissue-engineering scaffolds and other implanted biomaterials. Major advancements have been made relating to macrophage-based therapies and biomaterials. Macrophages have the potential to influence healing trajectory, and the predominance of specific subtypes at the early onset of healing influences overall repair outcomes. Macrophages exhibit significant plasticity with complex phenotypes ranging from proinflammatory (M1) to pro-regenerative (M2), and they release cytokines and chemokines that govern immunological stability, inflammation resolution, tissue healing, and tissue regeneration.

Bone cells interact with immune cells under physiological and pathological conditions. The new interdisciplinary field of osteoimmunology has highlighted the shared molecules, signaling pathways, and reciprocal interactions between the two systems in health and disease. Further, recent progress in this area has shown the potential of immune engineering strategies to develop new therapies to address bone-related ailments. This session focuses on the use of biomaterial systems to enhance, modulate or direct the immune response using biophysical or biochemical means toward bone healing, repair, and regeneration. Example biomaterial innovations include strategies for mobilizing immune cells in fracture milieu, modulating macrophage response, osteoblastogenesis or osteoclastogenesis, tackling immune dysfunction, and modulating the phenotype of naive immune cells using drug and gene delivery vehicles.

Immunomodulation and Cancer Imaging and Therapy using Nanomaterials

The aim of this symposium is to provide the biomaterials community with a unique forum to discuss the latest advances in (i) immunomodulation using nanomaterials (NMs) in biological and biomedical settings; (ii) cancer multimodal imaging using NMs from translational studies across organ systems to leading-edge technological developments; and (iii) non-invasive cancer therapies using actuated NMs and their implications in remotely controlled nanomedicines.

Over the past few years, there have been substantial progress in immunomodulation using NMs and its use in precision medicine. NMs administered intravenously are predominantly sequestered by the abundant phagocytes in spleen and liver, and a generation of NM researchers have struggled to find ways to keep them out of the phagocytes.  Delivered systemically or locally, with or without efforts to target NMs to other cells, most NMs will be ingested by phagocytes.  Looking at the efficient uptake of NMs by innate immune cells with an immune-centric viewpoint reveals the potential to use that phagocytic character to manipulate the innate cells and thereby manipulate the immune response. Depending on what the NM is made of and carries, the influence can be stimulatory to activate immune responses or suppressive to reduce already active immune responses. The symposium will highlight the many ways that NMs can be utilized to manipulate or inform about immune responses, and how NMs can be further exploited for cancer imaging and therapy.
As for cancer imaging, magnetic NMs find applications as contrast agents for MRI and as tracers for magnetic particle imaging (MPI). MRI is critical for visualizing soft tissue and organs. About one-third of over 60 million MRI scans are contrast-enhanced MRI. Magnetic NMs are considered safer alternatives to Gd-based contrast agents, which have recently shown adverse effects (e.g., nephrogenic systemic fibrosis and Gd deposition in the human brain, both being investigated by the FDA). MPI is an emerging molecular imaging technology that enables unambiguous, sensitive, and quantitative tomographic imaging of the biodistribution of magnetic NMs. Synthesis of magnetic NMs for MPI aims to improve resolution and signal-to-noise ratio, while advances in surface coatings aim to enhance blood circulation time, target disease sites, and enable tracking of cellular therapies. However, not only the imaging capability of magnetic NMs makes them suitable for clinical applications, but also their interaction with biological entities when remotely activated by exogenous polarizing fields, which endows them with extra potential as therapeutic agents to treat certain diseases. This could lead to the change of enzymatic activity on particle surfaces, selective cytoskeleton disruption of tumor cells, and remote control of cellular functionality as a result of the realignment of NM magnetic moments, which has the potential to cause detectable mechanical forces.

Immunomodulatory Biomaterials

This session will focus on engineered biomaterials to modulate and regulate immune functions in the settings of autoimmune diseases, allergies, transplantation, cancer immunotherapies, etc. Specifically, the session will cover topics ranging from biomaterials for drug delivery of immunomodulators and imaging agents, antigen delivery, scaffolds for immunomodulation, microbiome modulation, cell-based therapies, etc. Cutting-edge immunoengineering platforms will be included.

Immunomodulatory Biomaterials and Immune Cell Interfaces

The immune system is essential for tissue repair, regeneration, and homeostasis. Interactions with and among immune cells are critical to the success or failure of new therapies and medical devices. Further, harnessing and modulating the innate properties of immune functionality is a promising avenue to treat diseases, trauma, and congenital defects. This session aims to shed light on interfacial phenomena that occur between immune cells and tissues and on using biomaterial systems to enhance, modulate or direct the immune response, with the goal of better diagnosing or treating human diseases. Application areas include but are not limited to immune cell mobilization, immunomodulation using biomaterials, therapeutics (natural and synthetic), diagnostic devices/screening, implants, bioreactors, and modeling.

Incorporating Trained Immunity Concepts in Biomaterial Design

Trained immunity is an emerging concept that describes the phenomenon by which innate immune cells, especially macrophages, monocytes, and dendritic cells undergo metabolic reprogramming and epigenetic changes due to previous exposure to pathogens or endogenous stimuli. Understanding trained immunity can increase our ability to translate biomaterial technology to multiple disease contexts and by proxy multiple patient populations. Here we explore how biomaterials can be designed to modulate trained immunity responses.

Interfacing Biomaterials with Extracellular Vesicles

Cells naturally secrete diverse types of nanomaterials. In particular, recent studies highlight the role of lipid membrane-bound extracellular vesicles from cells in mediating various nanoscale biological processes, including intercellular communication, immunomodulation, and host remodeling. Emerging studies are showing different strategies to interface biomaterials with extracellular vesicles as a means to control their transport and retention with potential applications in disease modeling and tissue regeneration. The aim of the Symposium session is to introduce this new field to the biomaterials community and to feature recent progress in both fundamental and application-based studies that interface biomaterials with extracellular vesicles.

Interoception Mediated Musculoskeletal Tissue Regeneration

Central nervous system (CNS) has been found to play an important role in bone homeostasis. Indeed, the CNS receives signals from many physiological systems inside the body as interoception. It consists of ascending neural pathways that transmit the internal body signals to the brain, the CNS where the input interoceptive information is processed, and the descending neural pathways through which the interoceptive signals are circled back to regulate peripheral organs. Hence, this symposium aims to explore how biomaterials trigger or mediate the musculoskeletal tissue regeneration undergoing this specific pathway. 

Intersection of Biomaterials and Environmental Health

Biomaterials can play a pivotal role in understanding the impact of exposures to environmental pollutants on human health. This can be in the form of developing in vitro models (e.g., organ-on-a-chips) to assess toxicity, identifying mechanisms of mechanically-mediated chemical potency (e.g., ECM-chemical interactions), informing nanomaterial-cell interactions (e.g., nanoplastics), and understanding the role of environmental stressors in (eco)precision medicine (e.g., gene-environment interactions). The aim of this session is to inspire interdisciplinary collaboration between the fields of biomaterials and environmental health.

Manufacturing Dual Drugs Loading Liposomes Stimulated by Physical Activation

The drug delivery system using lipid nanoparticles is a method using biomaterials and is currently widely applied. It is used in many fields because its function also varies according to various types of lipids. These LNPs cannot carry many hydrophobic drugs in dual-drug delivery due to their structural characteristics.
In our study, we propose a method that can compensate for this drawback and deliver drugs more sensitively to the target. We give physical stimulation to LNPs to change the chemical properties of the head group. These changes enable more hydrophobic drug loading and more sensitive drug delivery according to environmental changes induced by breast cancer, a target cell.
This study makes it possible to treat cancer with more drugs, while reducing the amount of anticancer drugs that attack normal cells.

Nanomaterial Strategies for Immune Profiling

Profiling the immune system or complex systems at the single cell and analyte level is a helpful and necessary strategy to uncover important biomarkers that can lead to biological understanding driving the success or failure of various therapies. This session will explore research making an impact in this area, with a specific focus on nanotechnologies and other biomaterials approaches that help profile complex cellular phenotypes, patterns of cytokine expression, and cell or protein responses over time. Examples of these may include, but are not limited to: nanoparticles that bind to immune cells for phenotype characterization, in vivo biomaterials that recruit immune cells for ex vivo analyses, the use of interfacing biomaterial devices that enable investigation of immune cells or proteins.

Nanomaterials (SIG)

In this study, we show the effect of various LED wavelengths (blue, green, red and near infrared (NIR)) as physical regulators for gene delivery to stem cells by promoting nanomaterials behavior and regulating cell membrane permeability.
The size of nanoparticles produced with various LED wavelengths was evaluated in the colloidal state (agglomeration to single form). And physical stimulation of cell membranes using two type of LED wavelengths (blue and NIR) enhanced penetration of extracellular substances. The regulation of nanoparticle’s size and cell membrane permeability effectively increased the gene delivery to cells and protein expression by accelerating transfection process (cellular uptake, endosomal escape, PEI-gene dissociation).
LED effects on nanoparticles was confirmed using DLS, SEM, and Nanosight. In addition, cell membrane permeability was assessed by confocal laser microscopy, FACS and then transfection efficiency was demonstrated using confocal laser microscopy, FACS and Western blot.
Reduction of nanoparticles size by LED have potential value for stem cell therapy as LED-induced gene delivery system. Also, by increasing the cell membrane permeability, extracellular substances that cannot easily penetrate the cell membrane can be delivered effectively.

Nature Bioinspired Biomaterials and Strategies for TERM

Biologically derived polymers and composites offer excellent opportunities in the biomaterials field. This versatile class of materials includes biopolymers (polyhydroxy alkanoates, hyaluronic acid), polysaccharides (starch, chitin/chitosan, alginate) or proteins (collagen, fibrin, silk fibroin) enabling developing engineered systems with outstanding biological performance. The innovative use of its characteristics, taking advantage of the similar structure or composition with respect to biological tissues, enables designing high performance solutions for biocompatibility, biodegradability and bioactivity of biomaterials. Also the advanced areas of tissue engineering, drug delivery and smart/active/adaptative systems may benefit from the wealth of natural polymers existing in nature.

Overcoming the Ill Effects of Aging Around the World

Recent research has identified anti-aging strategies that extend a healthy life span. Nanosystems that promote neuroprotection and neuroregeneration to address nervous system problems in older patients is a strategy of high interest.  Eliminating or modifying the accumulation of senescent cells in the elderly is another new strategy. This international symposium will feature biomaterials research from around the world that is focussed on overcoming age-related diseases.  Drug delivery, tissue engineering or immune modulation approaches with applications to the nervous system, or musculoskeletal or inflammatory diseases are sought. These include neural targeted nanoparticles, bioactive hydrogels, and aged neural tissue testing platforms. Localized delivery of anti-aging drugs evaluated in aging animal models that down-regulate inflammaging will be highlighted. This symposium is co-organized by the European Society for Biomaterials and together we have aspirations to accelerate international scientific exchange and stimulate international collaboration.

Oxygen Imaging Assessment of Beta Cell Replacement Devices

This symposium will feature electron paramagnetic resonance oxygen imaging (EPROI) assessment of beta cell replacement devices aimed to cure type-1 diabetes (T1D). Various strategies to address the oxygen needs of beta cells have been devised in the field and therefore it is important to address three-dimensional noninvasive oxygen assessment of these devices. The symposium will cover educational topics detailing the principles and methods to acquire oxygen images as well as assessment of beta cell replacement devices in vitro and in vivo in small animals using EPROI. 

Pediatric Drug Delivery and Device Design

Children represent a small proportion of the sick population, and although this is fortunate, the market for pediatric drug formulations and medical devices to treat pediatric patients is small.  Additionally, the pediatric population as a whole (0-17 years) is heterogeneous with differing dosing and drug delivery requirements depending on the age and developmental and clinical state of the patient.  A special session within the Society for Biomaterials is highlighting this great need and also great opportunity for our research community to contribute to the development and manufacture of innovative advances for the treatment of pediatric patients.  We are currently accepting abstracts, so please share your advances in pediatric drug delivery and device design.  We have already contacted Dr. Anne Zajicek, former Director of the NICHD and current NIH Deputy Associate Director of the Office of Clinical Research, and she has offered to be our keynote speaker for the 2023 session. 

Peptides as Therapeutics and Biomaterials

Peptides are chemically defined and possess a wide range of biofunctions including ligand binding, proteolytic susceptibility, and self-assembly. Owing to these features, peptide-based biomaterials show wide range of capacities to encapsulate payload, to engage cellular receptors, respond to stimuli and surrounding environments, and modulate cell functions as drug or immune antigens. These unique advantages, along with an outstanding safety profile, make peptide-based biomaterials very attractive in a variety of biomedical applications including stimuli-responsive biomaterials, drug delivery, tissue regeneration, and immune modulation. This session will cover all aspects of peptide-based therapeutics and biomaterials ranging from fundamental concepts of self-assembly to therapeutic applications. We will feature recent advances in the development of biomaterials including, but not limited to, peptides acting as bioactive components, peptides functioning as targeting ligands, and peptides serving as scaffold building blocks. We will highlight applications including biomedical imaging, disease diagnosis and treatment, tissue regenerations, and immune modulations.

Sex as a Biological Variable in Biomaterials Research

Sex differences exist in both health and disease, yet our mechanistic knowledge of the underlying sex-specific molecular and cellular mechanisms involved remain poorly characterized. In terms of biomaterials, the effects of sex on processes such as fibrosis, wound healing, tissue regeneration, and immune rejection, are only now beginning to be appreciated. In this session, we seek to highlight the latest research in biomaterials-based technologies that enable sex-specific understanding of biological mechanisms in health and disease. Topics in this session include (and are not limited to) using biomaterials to design sex-specific cellular microenvironments, understand sex-specific disease pathologies and immune responses, and and develop sex-specific drug delivery and tissue engineered approaches. Incorporating sex as a biological variable in biomaterials research may enable the improved understanding of sex differences in health and disease and provide a path toward sex-specific therapies to help benefit diverse patient populations.

SFB-PRA (Postdoctoral Recognition Award)

The goal of this 3rd SFB PRA is to recognize excellence in future leaders of biomaterials in academia and industry by awarding the top abstracts submitted by SFB postdoctoral trainees.

Smart Biomaterials

Smart biomaterials (i.e., targeted, stimuli-, bio-responsive, autonomous) are those that change one or more of their properties in response to a stimulus. These biomaterial systems have great potential for the efficient delivery of therapeutics, increasing therapeutic activity, while decreasing toxicity and other adverse effects like drug resistance. This session will describe the state-of-the-art on the design, development, and application of smart biomaterials in different areas of medicine including tissue engineering, drug delivery, medical devices, tissue regeneration, antimicrobial, remineralization, self-healing, and immune engineering.

Stimuli-Responsive Biomaterials

Materials that respond to environmental stimuli, such as heat, light, pH, or biological signals, provide unique tools for environmentally-responsive and/or temporal changes in biomaterial properties over time. These materials have broad potential applications in drug delivery, cell-responsive materials, tissue engineering, and medical device implantation. This session will highlight recent advances in designing and characterizing stimulus-responsive biomaterials.

Tissue Engineering (SIG)

Tissue Engineering SIG is a forum to exchange information, further knowledge, and promote greater awareness regarding all aspects of the use of biomaterials to engineering tissue substitutes or to promote tissue regeneration. Of primary interest and relevance to TE SIG is the use of appropriate materials (synthetic and natural) with cells (either native or from a donor source) and/or biological response modifiers (e.g., growth factors, cytokines and other recombinant products) to replace tissue and organ functions. Particular emphasis is placed on the development of materials to better incorporate, protect, and deliver both the cells and biological response modifiers to help promote the healing and regenerative processes. The group is committed to forging interactions among basic scientists, applied scientists, engineers, clinicians, industrial members, professional societies in related fields, and regulatory groups in its efforts to expand and effectively utilize the shared knowledge base in this multidisciplinary field.

Translational Tissue Engineering Therapies in Preclinical Models of Injury and Trauma

A major goal of tissue engineering is to induce and precisely guide regeneration in vivo through the use of engineered biomaterials. The complex nature of living systems suggests the need for translational therapies that are interdisciplinary, often leveraging the fields of engineering, medicine, developmental biology, and stem cell science. This session seeks to highlight recent efforts to demonstrate the functional benefits of biomaterials for tissue engineering in preclinical in vivo models of injury, trauma, and disease. Specifically, we invite abstracts on research that highlights therapies further along the translational spectrum that elicit longer-term functional benefits (e.g., behavioral and/or anatomical) and transcend initial short-term metrics of retention, feasibility, and safety.

Underrepresented Voices in Biomaterials Science and Engineering

The purpose of this session is to highlight the research conducted by biomaterials scientists and engineers from historically excluded groups and marginalized communities, including but not limited to Black/African American, Hispanic/Latinx, and Native/Indigenous groups. Our session will consist of one invited keynote speaker and 10 short talks from submitted abstracts to our session. Note participation may require two presentations of your abstract submission.

Understanding Biomaterial Behavior is Key to Use of Digital Twins in Biomedical Research 

 Despite advances in research, the success rate for new treatments in clinical trials has not advanced in 20 years. The transition from success in animal models to success in humans remains the bottleneck as the human systems cannot be replicated in an animal model. However, in recent years multiscale digital twins of human organs and body systems have demonstrated the possibility to replace animals as the foundation of biomedical research. When developed through open mechanisms such as the Living Heart Project, they hold the promise of systematically growing in fidelity over time, allowing animals to be required as a safety screen prior to human testing. Uses include development of implanted devices, wearable sensors, drug and delivery systems and even complete organ regeneration. New and novel biological materials will be needed with greater flexibility and biocompatibility, as evidenced by the encouragement of the USFDA for more research and better community coordination.
