Gelatin’s Expanding Role as a Customizable Biomaterial in Regeneration
Gelatin is derived from collagen but offers greater tunability, making it a favorite in advanced regenerative therapies. Its ability to form hydrogels under mild conditions enables the creation of soft, cell-friendly environments. Gelatin supports excellent nutrient exchange, cell adhesion, and mass transport, all of which are essential for building new tissue.
Because gelatin is thermally responsive, clinicians and biomedical engineers can adjust its stiffness, degradation rate, and viscosity to meet the demands of specific treatments. For example, softer formulations are ideal for neural or adipose tissue, while stiffer variations support cartilage and bone. Gelatin also binds well with growth factors and therapeutic drugs, making it a powerful tool for controlled release systems.
Its accessibility and low cost make gelatin appealing for large-scale clinical use. Whether employed as a scaffold, wound dressing, injectable filler, or bioprinting material, gelatin continues to unlock new possibilities in tissue repair and regeneration.
