Gelatin scaffold

A gelatin scaffold is a three-dimensional biomaterial constructed from gelatin, a protein produced by the partial hydrolysis of collagen derived from animal connective tissues [1]. In the fields of tissue engineering and regenerative medicine, these scaffolds function as a synthetic extracellular matrix (ECM) that provides the necessary structural integrity and biochemical environment for cell attachment and growth [2]. Gelatin is uniquely suited for this role because it contains essential cell-signaling sequences, such as the Arginine-Glycine-Aspartic acid (RGD) peptide, which promote cell adhesion and migration [3]. These scaffolds are frequently used in wound care and bone regeneration, where they can be loaded with growth factors or antibiotics to provide localized, sustained therapeutic release [4]. While gelatin itself is not a traditional drug target like a receptor or enzyme, its physical and chemical properties are engineered to interact specifically with host cells and biological molecules to facilitate tissue repair [5]. However, challenges such as rapid degradation and potential immunogenicity from animal-derived sources require careful cross-linking and purification during manufacturing [1, 6].
