[Abstract]:Objective to investigate the effects of endomorphin 1 on intercellularadhesion molecule-1 (ICAM-1), (Vascular cell adhesion molecule-1 (VCAM-1) and the cytokine IL-6 / TNF-a secreted by stromal cells in normal bone marrow stromal cells. Methods Bone marrow stromal cells were isolated by Ficoll density gradient centrifugation and their surface markers were detected by flow cytometry. The expression of ICAM-1 and VCAM-1 was detected by flow cytometry and the concentration of cytokine IL-6 and TNF-a was detected by enzyme-linked immunosorbent assay (Elisa). Results the expression of adhesion molecules: the expression of ICAM-1 and VCAM-1 in normal bone marrow stromal cells cultured with endomorphin 1 for 24 hours was significantly different from that in control group (P < 0. 05), but at the same concentration of endomorphin 1, the expression of ICAM-1 and VCAM-1 in each experimental group was significantly higher than that in control group (P < 0. 05). The change of culture time had no significant effect on the expression of both. Levels of cytokines secretion: no significant difference was found in the concentration of IL-6 and TNF-a between the dose-response and time-dependent groups (P > 0.05). Conclusion 1 morphine peptide 1 can regulate the normal bone marrow base. The expression of ICAM-1 and VCAM-1 on the cytoplasm. 2 morphine peptide 1 had no obvious effect on the cytokine IL-6 and TNF-a secreted by normal bone marrow stromal cells.
