abstract = {Aim: To investigate the effects of panax notoginosides (PNS) on the proliferation of human hematopoietic stem/progenitor cells, and to explore the signaling pathway of the nuclear transcription factor of the glucocorticoid receptor (GR-NTF) initiated by PNS related with the proliferation.
Methods:
The human CD34+ cells and bone marrow nuclear cells were exposed to PNS at a concentration of 0, 10, 25, 50, and 100 mg/L, respectively, in semi-solid culture system to observe colony forming unite of all lineages, granulocyte, erythrocyte, and megakaryocyte (CFU-GEMM, CFU-GM, CFU-E, and CFU-MK). Three lineages of human hematopoietic cell lines, including granulocytic HL-60, erythrocytic K562, megakaryocytic CHRF-288, and Meg-01 cells were incubated with PNS at 20 mg/L for 14 d. Meanwhile, dexamethasone (Dex) was used as a positive control. The nuclear protein of the cells was analyzed by Western blotting with monoclonal antibodies against the amino or carboxyl terminus of GR-NTF. Electrophoretic mobility shift assay performed by using the 32P-radiolabeled GR-NTF consensus oligonucleotide.
Results: PNS promoted the proliferation of CD34+ cells and significantly raised the colony numbers of CFU-GEMM by 34.7%±16.0% over the non-PNS control (P},
