ABSTRACT
In order to explore the expansive effect of human placental cell-free suspension (HPCFS) on bone marrow hematopoietic stem/progenitor cells, and to compare the effect of HPFCS with some cytokines and their combination, human marrow CFU-GM, CFU-GEMM and BFU-E were assayed in a semisolid methyl cellulose culture system using HPCFS, IL-3, GM-CSF, and IL-3 + IL-6 + GM-CSF + EPO as colony stimulating factors, respectively. The results showed that HPCFS stimulated the growth of CFU-GM, CFU-GEMM and BFU-E and the optimal concentrations for stimulating effect were 200 - 300 micro g protein/L, and the yield of 3 kinds of colony in HPCFS group was higher than that in IL-3, GM-CSF and IL-3 + IL-6 + GM-CSF + EPO groups. The expansive effect of HPCFS on marrow progenitors was superior to IL-3, GM-CSF and IL-3 + IL-6 + GM-CSF + EPO. Human placental cell-free suspension contained a variety of cytokines to stimulate proliferation of hematopoietic stem/progenitor cells, and it could be used as an efficacious and inexpensive agent to expand hematopoietic stem/progenitor cells in vitro.
