Scaffolds are three-dimensional structures designed to support cell attachment, migration, proliferation, differentiation, and tissue formation. In tissue engineering and regenerative medicine, scaffolds can be made from polymers, ceramics, metals, hydrogels, extracellular matrix materials, nanofibers, composites, or bioactive glasses. Their performance depends on porosity, pore connectivity, stiffness, degradation rate, surface chemistry, architecture, and ability to deliver biochemical or mechanical cues.
Scaffolds matter because cells respond strongly to the physical and chemical environment around them. Well-designed scaffolds can guide tissue repair, support vascularization, deliver growth factors, and mimic aspects of native extracellular matrix. They are studied for bone, cartilage, skin, nerve, vascular, cardiac, and dental tissue engineering, as well as drug screening and disease models. Nanoscale features can improve cell adhesion, matrix organization, mechanical reinforcement, and bioactivity. The topic connects closely to tissue engineering, biomaterials, hydrogels, and biofabrication.
Conferences on scaffolds appear in biomaterials, regenerative medicine, tissue engineering, nanomedicine, biofabrication, and medical-device programs. Sessions often cover scaffold architecture, electrospun fibers, 3D printing, degradation, mechanical testing, and cell response. Tracking scaffold events helps researchers follow how engineered structures create environments for tissue growth and repair.
