Notch signaling is an important mechanism involved in early development which helps to determine the differentiation and fate of cells destined to form different tissues in the body. Its role in the differentiation of adult stem cells, such as those found in bone marrow is much less clear. As there is great interest in the potential of human bone marrow stem cells (hMSC) as a source of cells for the...
Recently there has been increased interest in the regulatory interactions between osteoblasts and cells in the surrounding bone marrow microenvironment. The proximity of hematopoietic stem cells (HSCs) with osteoblastic cells first suggested regulatory interactions, and recent data have highlighted the role of osteoblastic cells in providing a HSC niche. Reports have indicated that direct contact...
Evolutionarily conserved Notch signaling plays a critical role during embryonic and postnatal life. The importance of Notch signaling in the determination of cell fate, and the spatio-temporal regulation of proliferation, differentiation and apoptosis has been demonstrated in various different organ systems. However, how Notch signaling affects the bone development was unknown until now. The in vivo...
