Bone morphogenetic protein 6 drives both osteogenesis and chondrogenesis in murine adipose-derived mesenchymal cells depending on culture conditions
چکیده انگلیسی

Bone morphogenetic proteins (BMPs) play a dual role as a factor in both bone and cartilage development and correspondingly have the therapeutic potential to regenerate both tissues. Given this dual nature, previous in vitro research using BMPs has relied on distinct media formulations and culture conditions to drive undifferentiated cells to the osteogenic or chondrogenic lineage. To isolate the impact of culture conditions and to explore the effect of BMP-6 on murine adipose-derived mesenchymal cells (ASCs), ASCs were seeded in either monolayer or pellets in an identical medium containing BMP-6. Results indicate that BMP-6 differentially promotes osteogenesis and chondrogenesis in ASCs depending on culture conditions. BMP-6 potently induced alkaline phosphatase activity and mineralization in ASCs cultured in monolayer conditions. In contrast, BMP-6 enhanced proteoglycan accumulation in ASCs seeded in chondrogenic pellet culture. A comparison of gene expression suggests that the differentiating effect of BMP-6 is specific to the particular culture condition. This study highlights the importance of the interactions between chemical signaling and microenvironmental cues in directing cell fate.

Research highlights
► BMP-6 promotes osteogenesis in murine ASCs in monolayer.
► BMP-6 also induces chondrogenesis in murine ASCs cultured in pellets.
► Both osteo- and chondrogenesis can be induced with a single medium containing BMP-6.
► The osteogenic and chondrogenic effects of BMP-6 are specific to the culture conditions.
