title: Comparison of multipotent differentiation potentials of murine primary bone marrow stromal cells and mesenchymal stem cell line C3H10T1/2.
abstract: Murine C3H10T1/2 cells have many features of mesenchymal stem cells (MSCs). Whether or not the multipotent differentiation capability of C3H10T1/2 cells is comparable to that of primary bone marrow-derived MSCs (BM-MSCs) was investigated in this study. For in vitro osteogenic differentiation, both BM-MSCs and C3H10T1/2 cells differentiated to osteoblastic cell lineage and showed positive staining for alkaline phosphatase (ALP) and increased mRNA expression of Runx2, Col1alphaI, and osteocalcin. C3H10T1/2 cells and BM-MSCs induced similar amounts of bone formation in the biomaterials. Under chondrogenic induction in the presence of TGF-beta1, cell pellets of both BM-MSCs and C3H10T1/2 cells formed cartilage-like tissues with cartilage matrix components including proteoglycan, type II collagen, and aggrecan. However, C3H10T1/2 cells presented lower adipogenic differentiation potential, with only about 10% C3H10T1/2 cells (but about 70% of BM-MSCs) being committed to adipogenesis. In this study we confirmed that C3H10T1/2 cells coimplanted with osteoconductive scaffolds can form bone spontaneously in vivo and that C3H10T1/2 cells have a basal level of osteocalcin expression, suggesting that they may be a good alternative source of primary BM-MSCs for investigating osteogenic and chondrogenic differentiation in bone or cartilage tissue engineering studies. Caution is needed when using C3H10T1/2 cells for adipogenic studies as they appear to have lower adipogenic potential than BM-MSCs.
