Recently, we described an efficient cross-linking process via the formation of acyl azide groups on methylated carboxyl groups of collagen using hydrazine and nitrous acid referred to here as the hydrazine method. Application of Collagen Scaffold in Tissue Engineering: Native and Herbate cross-linked collagen sponges seeded with fetal bovine epiphyseal chondrocytes used for cartilage tissue engineering.

Topics Discussed in This Paper. Similar decreases in free primary amino group content and increases in thermal stability were obtained for collagen films treated with DPPA, glutaraldehyde, or hydrazine.

Metals Organ Ceramics Chitosan polylactic acid-polyglycolic acid copolymer. After determining the optimal conditions of cross-linking with DPPA, we compared the efficiency of this protocol with that using hydrazine and with the classical glutaraldehyde treatment. Specific cartilage collagens types II and XI were deposited in the matrix throughout the culture and traces of type I collagen were noticed only in the culture vollagen after weeks and 4 weeks in the case of 10 6 and 10 7 cells-seeded sponges, respectively.

Both supports were always present during the study and a partial decrease in size and weight was detected only with control sponges, both seeded and unseeded.
