Outline of Final Research Achievements

To understand molecular mechanisms underlying vascular stem cell development, we analyzed functions of a key transcriptional complex consisting of LHW and T5L1. We revealed that LHW-T5L1 non-cell autonomously regulates vascular stem cell proliferation through the regulation of cytokinin action. We also showed that LHW-T5L1 regulates factors, which form feedback loops to control the LHW-T5L1 activity.
