The substrate in this case is gelatin, and the products are the polypeptides formed. Gelatinase binds to the substrate, gelatin, due to specificity of binding interactions on cell surface. The catalysis, associated with a zinc ion and amino acid residues, breaks the peptide bonds into polypeptides through cleavage.
Cells in Wharton's jelly express several stem cell genes, including telomerase. They can be extracted, cultured, and induced to differentiate into mature cell types such as neurons . [ 3 ] Wharton's jelly is therefore a potential source of adult stem cells , often collected from cord blood .
