title: [Effects of murine bone marrow endothelial cell conditioned medium in combination with FL and TPO on the growth of HPP-CFC and CFU-GM].
abstract: In the present study, the effects of murine bone marrow endothelial cell conditioned medium (ECM) combined with flt3 ligand (FL) or/and thrombopoietin (TPO) on the proliferation of HPP-CFC and CFU-GM were investigated. Both ECM and the concentrated retentate of ECM (MW>10 kD) promoted the growth of CFU-GM and HPP-CFC, and this promoting effect was further enhanced by addition of FL or TPO. Using reverse transcriptase-polymerase chain reaction (RT-PCR) technique, the expression of FL and TPO mRNA was not found in murine bone marrow endothelial cells.
