| Research Abstract |
The percentage of 6pLOH was different among hematopoiesis stages in human bone marrow, and the progenitor cells showed much lower percentage of 6pLOH than that of MEP and GMP.
I found approximately 30 times lower expression of CXCL12 which promotes the cell growth and proliferation cytokine than that of normal fraction with microarray analysis. As a result, I demonstrated the percentage of HLA deficient was significantly decreased, since the cell cycle was not promoted in the 6pLOH of CMP fraction with low CXCL12 and CXCR4 expression.
