|a Osteoblasts (OST) provide strong intrinsic growth modulatory activities on hematopoietic stem and progenitor cells via different mechanisms that include secretion of growth factors, and cellular interaction. Previously we showed that medium conditioned by mesenchymal stromal cell (MSC)-derived osteoblasts (MOST) improve the expansion of cord blood (CB) CD34+ cells. I hypothesize that the hematopoietic supporting activity of M-OST would vary as a function of their maturation. This was tested by producing osteoblast conditioned media (OCM) from M-OST at distinct stages of maturation, and testing their growth regulatory activities in CB CD34+ cell cultures. My results showed that some of the growth promoting activity of OCM on CB cells are not dependent on the maturation status, while others are and those are largely independent of Notch signalling. In conclusion, these results provide further evidence that osteoblasts release factors that can promote the growth of immature CB progenitors in a Notch-independent way.
