Primitive, proliferating hematopoietic progenitors (defined as
cytokine low-responding primitive progenitors; CLRPP), isolated from
human CD34+ cells, expressed endoglin (CD105) and produced transforming growth factor- 1 (TGF- 1). Culture of CLRPP in
serum-free conditions with anti-TGF- 1 monoclonal antibody produced a
substantial decrease in bcl-2 protein/RNA levels and a significant
reduction of cloning and long-term culture-initiating cell (LTC-IC)
activities. GATA-1 and PU.1 RNA levels were significantly up-regulated
in anti-TGF- 1-treated CLRPP, which generated an increased number of
cells expressing CD15/CD11b/glycophorin-A. The described effects of
TGF- 1 neutralization were observed in the absence of any relevant effect on cell cycle; number of cell divisions; p53, c-myc, and p21 RNA
levels; bcl-xL and bax protein levels; and c-myc/p16/p21/p107/Rb cell
cycle-related protein levels. A relevant increase in p27 protein
levels was observed in anti-TGF- 1-treated CLRPP, suggesting a role
for p27 in the regulation of the hematopoietic potential. The present
study on human progenitors and previously reported data on TGF- 1
knockout mice suggest that, at the autocrine level, the cell cycle
inhibitor TGF- 1 plays an important role in regulating the survival
and differentiation of primitive proliferating hematopoietic progenitors by cell cycle-independent mechanisms.
