Outline of Final Research Achievements |
Understanding of the mechanism of stemness maintenance in mesenchymal stem cells (MSC) is important for the future cellular therapies. In this study, I focused on the transcription factor, KLF4 and analyzed the effects of KLF4 knock-down by short hairpin RNA in human bone marrow-derived MSC. Those MSCs showed significantly increased the proliferation rate and the adipogenic differentiation. The osteogenic differentiation was also increased, but not significant. Further, the microarray data in KLF4 overexpressed MSC indicated that KLF4 suppresses the genes for cell cycle and some receptors for cellular signaling pathways. These results suggest that KLF4 has an important function for the multipotency of MSC.
