Biomaterials are materials engineered to interact favorably with biological organisms or molecules. These materials can be derived from or produced by an organism, or can even be a synthesized polymer. Engineers use these novel materials in a wide range of applications, such as tissue engineering, biosensing and drug delivery. This video introduces common biologically derived materials, and provides examples of common techniques used to process them. Key challenges in the field are discussed,...

Silk fibers have been processed and used to create fabrics and threads for centuries. However, the solubilizing of silk fibers, thereby turning it into a versatile pre-polymer solution is a much newer technology. Solubilized silk can be processed in many different ways to create a biocompatible material with controllable mechanical properties. This video introduces the processing of silk from silk worm cocoons, and shows how the silk solution can be used to create a fiber mat via...

Human perivascular stem cells (PSCs) are a novel stem cell class for skeletal tissue regeneration similar to mesenchymal stem cells (MSCs). PSCs can be isolated by FACS (fluorescence activated cell sorting) from adipose tissue procured during standard liposuction procedures, then combined with an osteoinductive scaffold to achieve bone formation in vivo.

FAQs
Performance depends on how a scaffold’s three-dimensional architecture presents surfaces and spaces for cells. Its structure can guide cell attachment and proliferation, while the material’s chemical composition and biological signals influence subsequent new tissue formation. In bioengineering, these features are considered together because changing one property can affect how effectively the construct supports organized bone repair.
Mechanical stability and biological regeneration must be coordinated rather than treated as separate goals. A material needs to provide structural support during repair while also permitting the biological processes associated with new tissue formation. Research therefore examines how physical structure, composition, and biological signals work together, because a design that supports one requirement may not adequately address the other.
Gradual degradation allows a material to change as repair progresses, whereas integration connects the material with nearby bone. These behaviors affect whether support persists while new tissue develops and whether the implant becomes compatible with its environment. For this reason, biomaterial design considers not only initial structure, but also how the material behaves over time during bone repair.
Designers balance physical structure, chemical composition, biological signals, and the material’s tendency to degrade or integrate. The target is not a single ideal property, but a coordinated combination that can provide structural support, guide cell behavior, and promote new tissue formation. This balance is central to bioengineering strategies for repairing damaged bone and improving healing outcomes.
The application determines how the material contributes to repair. In bone defect repair, it can provide a supportive three-dimensional environment; as an implant coating, it can contribute to the interface surrounding an implant; and in tissue-engineered grafts, it can support cell activity and new tissue formation. Across these uses, the intended outcome is improved structural support and healing.
Matching native bone properties may help biomaterials function more appropriately within the repaired region. Current research therefore focuses on designs that combine suitable physical characteristics with chemical and biological features capable of supporting regeneration. This goal is relevant to bioengineering because successful materials must coordinate mechanical stability with biological healing rather than rely on structural support alone.
