The Li laboratory focuses on exploiting bioengineering strategies for tissue regeneration by combining the principles of biomaterial science, biological science, stem cell biology, tissue engineering, regenerative medicine with the advanced techniques in molecular and cell biology. Specifically, we aim to develop biomaterial approaches to induce a permissive microenvironment to improve efficiency of stem cell therapies for regeneration of injured/diseased tissues. We also apply biomaterial platforms to influence endogenous cell fates to promote functional tissue regeneration.
