April 2023

Guan lab attended Society for Biomaterials conference in San Diego. Jiaxing presented “Targeting Tissue-resident Macrophage Secreted MCP-1 for Attenuating Inflammation After Myocardial Infarction.”

December 2022

Sherry has been promoted to Research Assistant Professor in the Department of Mechanical Engineering and Materials Science. Congratulations!

November 2022

Ya’s paper “Rescuing Cardiac Cells and Improving Cardiac Function by Targeted Delivery of Oxygen-Releasing Nanoparticles after or Even before Acute Myocardial Infarction” has been published in ACS Nano. Congratulations! In this work, we demonstrated that the oxygen-releasing nanoparticles, delivered either pre-MI or post-MI, enhanced cardiac cell survival, stimulated angiogenesis, and suppressed fibrosis without inducing substantial inflammation and reactive oxygen species overproduction. These nanoparticles can provide a nonpharmacological solution to rescue the infarcted heart during acute MI and preserve heart function.

October 2022

Guan lab attended BMES in San Antonio, TX. Sherry had an oral presentation entitled “Preserve and vascularize cardiac extracellular matrix after acute myocardial infarction.” Tina presented a poster entitled “Co-delivery of engineered cell membrane repair protein and mesenchymal stem cells to promote vascularization and muscle repair in ischemic hindlimbs of diabetic mice.”

October 2022

Yu started her new position as a Research Scientist at Charles River Laboratories. Congratulations!

August 2022

Dr. Guan has been awarded a new NIH R01. The focus of this 4-year, ~$1.9 million grant is wound healing under diabetic and aging conditions. In this project, we will develop multifunctional hydrogels and differentially control TGFβ pathway to accelerate wound closure. Dr. Liang Ma of Internal Medicine, and Dr. Mohamed Zayed of Surgery and of Radiology, are co-investigators of this grant.
