Abstract: A scaffold for promoting cartilage formation is provided that includes a crosslinked electrospun fiber, wherein the crosslinked electrospun fiber consists essentially of crosslinked gelatin. The crosslinked electrospun fiber is generally crosslinked with a crosslinker, and the crosslinker may be diisosorbide bisepoxide. The crosslinked electrospun fiber may be crosslinked by adding a crosslinker to a solution of gelatin at a desired concentration. The electrospun fiber may advantageously remain intact for 18 days or longer upon being immersed in an aqueous solution. A composition for promoting cartilage formation is also provided that includes the disclosed scaffold and a mesenchymal stem cell (MSC). The disclosed scaffold may include a crosslinked electrospun fiber that includes gelatin and sodium cellulose sulfate (NaCS), e.g., in an amount of up to 5% by weight of the amount of gelatin.
