Endogenous bone morphogenetic proteins in human bone marrow-derived multipotent mesenchymal stromal cells

Primary human multipotent mesenchymal stromal cells (MSCs) are capable of self renewal or differentiation into several different lineages, including osteoblasts, chondrocytes and adipocytes. However, upon prolonged in vitro culture, MSCs tend to undergo spontaneous osteogenic differentiation. Here, we address the possible role of endogenous osteogenic bone morphogenetic proteins (BMPs) in in situ osteoblastic differentiation of human MSCs. Human...
