[Expression of apoptosis-related proteins in the human bone marrow hematopoietic cells treated by Panax Notoginosides].

The study was aimed to investigate the action of Panax Notoginosides (PNS, extracted from notoginseng herb) on the expression of the apoptosis-related proteins (Daxx, Fas) and transcription factors (NFkB, c-Rel) in the hematopoietic cells and to explore the mechanisms of supporting cells to survive. The colony formation of CFU-GM and CFU-E in human bone marrow was assayed in the presence of various concentrations of PNS. The viability of cells was assayed by trypan blue and the changes of cell morphology were observed with microscope.
