Abstract
The present study is to investigate human chondrocytes behavior on microcontact printed bone morphogenetic protein-2 (BMP-2) lines on polystyrene (PS) surface. It was found that the cells aligned with BMP lines and expressed type II and VI collagen. The chondrocytes in vitro cultured on BMP lines were elongated, which resulted in altered cell morphology. Taking all these results into consideration, BMP-2 lines enhance cell adhesion, restrict spreading, and increase type II and VI collagen expression. The results represented in this study may be an approach to the problem of engineering reparative cartilage in vitro.
