Mesenchymal progenitors and the osteoblast lineage in bone marrow hematopoietic niches.
Mesenchymal progenitors and the osteoblast lineage in bone marrow hematopoietic niches. Current osteoporosis reports Panaroni, C., Tzeng, Y., Saeed, H., Wu, J. Y. 2014; 12 (1): 22-32Abstract
The bone marrow cavity is essential for the proper development of the hematopoietic system. In the last few decades, it has become clear that mesenchymal stem/progenitor cells as well as cells of the osteoblast lineage, besides maintaining bone homeostasis, are also fundamental regulators of bone marrow hematopoiesis. Several studies have demonstrated the direct involvement of mesenchymal and osteoblast lineage cells in the maintenance and regulation of supportive microenvironments necessary for quiescence, self-renewal and differentiation of hematopoietic stem cells. In addition, specific niches have also been identified within the bone marrow for maturing hematopoietic cells. Here we will review recent findings that have highlighted the roles of mesenchymal progenitors and cells of the osteoblast lineage in regulating distinct stages of hematopoiesis.
