The objective of the study is to explore the effect of Fas, FasL and Bcl-2 on the process of apoptosis induced by chemotherapeutic drugs through detecting the expression of Fas, FasL and Bcl-2 on murine lymphoma cell line RMA. Dexamethasone(DEX), etoposide (VP-16), arsenic trioxide As(2)O(3) and all trans-retinoic-acid (ATRA) were added to the RMA cells as(More)
To study immunophenotype and cytotoxicity of the immunocytes in bone marrow and peripheral blood after activation by combined cytokines, mononuclear cells (MNC) of bone marrow and peripheral blood were activated by IFN-gamma, IL-1, IL-2 and McAb-CD3 in vitro. The cell amount and morphology during culture were observed. Cytochemical staining and(More)
OBJECTIVE To study the anti-tumor angiogenesis effect of soluble VEGF receptor fragment by blocking the combination of VEGF and its receptor in vivo and in vitro. METHODS RT-PCR technique was used to amplify Flk-1/KDR fragment from embryo mouse liver, which was recombinated to expression vector pET-28b(+) and retrovirus vector PLXSN, which was induced to(More)
OBJECTIVE To screen and identify differentially expressed proteins of mesenchymal stem cells (MSC) during endothelial differentiation. METHODS MSCs were induced to endothelial differentiation with vascular endothelial growth factor (VEGF) and epithelial growth factor (EGF) mixture. The whole cell proteins were extracted and isolated by two-dimensional gel(More)
AIM To analyze gene expression difference between human mesenchymal stem cells and umbilical vein endothelial cells, to discuss the feasibility of inducing hMSCs to differentiate into endothelial cells through in vitro gene transfection as well as the use and prospective as a seeding cell source of vascular tissue engineering. METHODS hMSCs and hUVECs(More)
