Experimental study of the effect of Angelica polysaccharide on proliferation and differentiation of human CFU-GM and HL-60 cells / 重庆医科大学学报

ABSTRACT

Objective:To study modern biological mechanism for hematonic and antitumor of Angelica Sinensis (oliv) Diels.Methods:By using the techniques of hematopoietic cells culture in vitro,morphological observation,flow cytometry and immunocytochemistry,the effect of Angelica polysaccharide (APS) on proliferation and differentiation of human CFU-GM and promyelocytic leukemia cell line (HL-60) was studied.Results:APS could markedly promote the colony formation of CFU-GM and could significantly inhibit the proliferation of HL-60 in vitro.The inhibitory effect is concerned with the concentration of APS.APS may prevent HL-60 from the Go phase entering the S/G2+M phase,thus prohibit the synthesis of DNA.APS may also promote HL-60 entering the process of apoptosis.Conclusion:APS may not only promote normal hematopoiesis,but also inhibit the proliferation of leukemia cell and it can be a natural inducer for therapy of malignant tumor.
