摘要: Publisher Summary Among mammalian stem cells, the best characterized are hematopoietic cells (HSCs). Stem have unique properties of self-renewal and multipotency, ability to use for therapeutic purposes holds tremendous appeal. Therefore, regulatory mechanisms governing cell function an area great scientific public interest. A single HSC can reconstitute entire system in vivo, HSCs been used with clinical benefit bone marrow transplantation. Maintenance differentiation dependent upon presence a supportive microenvironment, or niche. In adult mammals, takes place within cavity, Schofield first proposed concept microenvironment over 30 years ago. The appearance hematopoiesis bones coincides onset mineralization during skeletal development, recent decades, it has become apparent that marrow, surrounding non-hematopoietic tissues, play active role regulating hematopoiesis. stromal environment comprises multitude cellular components, including fibroblasts, endothelial adipocytes, osteoblasts. addition, lineage themselves likely also regulate microenvironment. This chapter highlights data regarding osteoblast
