The objective of this study is to investigate the attachment, osteogenic differentiation, and collagen matrix secretion of rat bone marrow stromal cells (MSC) and MC3T3-E1 cells on the biological apatite (Ap) with different crystalline facets. The Ap samples with a-facet and c-facet surfaces were prepared by cutting the heat-treated cortical bone of bovine femurs parallel and perpendicular to the longitudinal direction, respectively. MC3T3-E1 cells attached spreading on the a-Ap sample whereas their shape of cells was round on the c-Ap. No difference in the proliferation profile of MSC and MC3T3-E1 cells was observed between the two samples. The activity of alkaline phosphatase was significantly higher for both the cells on the a-Ap sample than that of c-Ap one. The matrix of collagen secreted from MC3T3-E1 cells on the a-Ap sample oriented along the c-axis of Ap, in contrast to those of c-Ap. The cells tended to align along the collagen orientation. It is concluded that the alignment of cells is influenced by the collagen fibril orientation of Ap samples.
