TGF-β1 Directs Chondrogenic Differentiation of Monocytic Precursor Cells

Autor: Kelly Rr, Xiong Y, Cray Jj, LaRue Ac, Wilson Kr

Publikováno v: Journal of Bone Marrow Research.

Bone marrow consists of two types of stem cell populations, the hematopoietic stem cell (HSC) and the mesenchymal stromal cell (MSC). While MSCs have been demonstrated to have the capacity to differentiate into osteoblasts, chondrocytes, and adipocyt
