Research Summary

Li-Kun  Phng(Ph.D.)

The establishment of a blood vascular system is essential for the development of many tissues. Tissue vascularization frequently occurs through angiogenesis, which consists of many cellular processes including polarized collective cell migration, anastomosis and lumen formation.

My laboratory aims to unravel fundamental mechanisms that regulate endothelial cell dynamics and coordination during blood vessel morphogenesis. Previous studies on actin cytoskeleton revealed that specialized actin structures of different dynamics and subcellular localization drive distinct steps of vessel morphogenesis. In the future, we will 1) investigate how force regulates endothelial cell dynamics and vessel morphogenesis, and 2) identify new molecular regulators of vessel lumen formation. Our long-term goal is to understand how upstream angiogenic signals and haemodynamic forces regulate force generation in endothelial cells and their behavior.
