The purpose of this investigation was to examine by reverse-transcriptase polymerase chain reaction analysis the osteogenic differentiation of twice-passaged Sprague-Dawley rat bone marrow stromal cells in type I collagen gel cultured for 3 weeks. Two culture media were used here, namely Dulbecco's modified Eagle (DME) medium supplemented with vitamin C [Dex (-)] and those with vitamin C, dexamethasone and beta-glycerophosphate [Dex (+)]. Culture with Dex (-) medium in collagen gel for 3 weeks brought about the well-developed cell network and middle-stage osteogenic phenotype expression characterized by mRNA for alkaline phosphatase, osteonectin and osteopontin while those for bone sialo protein and osteocalcin were not detected. On the contrary, culture with Dex (+) medium in collagen gel for 3 weeks lead to necrosis of the cells. These results indicate that culture in collagen gel with Dex (-) DME medium containing vitamin C was useful for three-dimensional culture and middle-stage osteogenic differentiation of twice-passaged bone marrow stromal cells. This study might contribute to tissue engineering therapy to fix bone and periodontal defects in the future.
