ABSTRACT
Objective To explore the biological characteristics and to compare the different regulation mechanisms of bone marrow mesenchymal stem cells(MSCs)derived from both lupus(MRL/Ipr)and normal (C57BL/6)mice on T iymphoeytes in vitro. Methods MSCs from MRL/lpr and C57BL/6 mice bone marrow were isolated and cultured. The surface phenotypes were detected by flow cytometry(FCM). The morphologi- cal changes of MSCs were evaluated in primary and passage cultures. The growth curves were assayed. CD3~+T lymphocytes from spleen of C57BL/6 mice were isolated by nylon wool columns and stimulated by ConA and co-cultured with or without the two strains of MSCs or supernatant for 72 h. The proliferation of T cells stained by CFSE and activation of T cells were detected. The apoptosis was assessed by now cytometry using Annexin V/PI. Results The growth of lupus MSCs was faster than normal controls(P
