Chitosan scaffolds with sponge-like structures were prepared by a wet spinn
ing technique. Glutaraldehyde was used to control the swellability (water u
ptake) of the scaffolds. It was possible to reach a swelling ratio about 56
.8% in aqueous medium. These wet scaffolds were soft and easily shaped by h
and. The cartilage specimen was obtained from the knee joints of a New Zeal
and white rabbit. Chondrocyte cells were isolated and cultured in vitro for
about 10 days to reach a usable population. The cells were then incubated
with the chitosan scaffolds and interactions were examined by microscopy. C
hondrocyte cells showed junctional complexes consisting of plaques and fila
ments at the interface. Cell membranes were strongly attached on the chitos
an surface.
