RESUMEN
Mesenchymal stem cells (MSCs) are capable of self-renewal and differentiation into lineages of mesenchymal tissues that are currently under investigation for a variety of therapeutic applications. The purpose of this study was to compare cytokine gene expression in MSCs from human placenta, cord blood (CB) and bone marrow (BM). The cytokine expression profiles of MSCs from BM, CB and placenta (amnion, decidua) were compared by proteome profiler array analysis. The cytokines that were expressed differently, in each type of MSC, were analyzed by real-time PCR. We evaluated 36 cytokines. Most types of MSCs had a common expression pattern including MIF (GIF, DER6), IL-8 (CXCL8), Serpin E1 (PAI-1), GROalpha(CXCL1), and IL-6. MCP-1, however, was expressed in both the MSCs from the BM and the amnion. sICAM-1 was expressed in both the amnion and decidua MSCs. SDF-1 was expressed only in the BM MSCs. Real-time PCR demonstrated the expression of the cytokines in each of the MSCs. The MSCs from bone marrow, placenta (amnion and decidua) and cord blood expressed the cytokines differently. These results suggest that cytokine induction and signal transduction are different in MSCs from different tissues.

OBJECTIVE: The present study was performed to evaluate the association of p53 codon 72 polymorphism and endometriosis. MATERIALS AND METHODS: We investigate 74 women who were operated for endometriosis and 93 women who had no endometriotic lesion proved by operation. Polymerase chain reaction was used to detect p53 codon polymorphisms. Result: We have found no significant difference between endometriosis and control group in the p53 codon polymorphism. The respective proportion of arginine homozygotes, heterozygotes and proline homozygotes in endometriosis group were 18.9%, 62.2% and 18.9%, respectively, and were 12.9%, 75.2% and 11.9%, respective in the group without endometriosis. CONCLUSION: Endometriosis is not associated with p53 polymorphism in Korean endometriosis patients.
