L-lactide—cholester01)(LC)was synthesized by bulk polvmerization.The molecular weights of LC obtained from 1H-NMR and GPC were in good agreement with the theoretical values.which indicate that the LC molecular weight can be adjusted by varying the D
5-diphenyl-2H-tetrazolium bromide(M'IT)cell activity on LC and poly(D
L-latic acid)(PLA)were investigated.The results showed that LC exhibited improved cell attachment and significantly better proliferation compared with pure PLA.The confocal laser scanning microscopy(CLSM)images showed that the number of chondracytes on PLA films was 1ess than that on LC.The chondrocytes on LC are spreading uniformly and completely while the chondrocytes on PLA are clotted and not in a normal spreading status.A1l the results above demonstrate that cholesterol-containing materials can construct a chondrocyte compatible surface and may have potentials for cartilage tissue engineering and other biomedical applications.
