Webinar Featuring Sharon Gerecht and Bria Macklin

June 2, 2022 1:00 PM - 2:00 PM (EDT)

Description

"Endothelial cell differentiation, regeneration and morphogenesis" will feature Dr. Sharon Gerecht, Duke University and Dr. Bria Macklin, UCSF/Gladstone Institutes 

Description

Vascular differentiation, regeneration and formation (morphogenesis) and eventual homeostasis occur in a complex milieu. Two aspects of this microenvironment seem critical for blood vessel growth and stabilization: (i) the extracellular matrix, which provides critical support for vascular cell adhesion, proliferation, migration, and morphogenesis, and (ii) low oxygen concentrations (hypoxia), which is a critical factor promoting vascularization during embryonic development, injury, and tumor growth. In this talk, we will present our recent efforts to develop and use engineering approaches to understand how these physicochemical cues and downstream signaling pathways impact vascular assembly and regeneration, leading to fundamental knowledge and future therapeutics. 

Biography
Sharon Gerecht, PhD
Dr. Gerecht is a Professor in the Department of Biomedical Engineering at Duke University. She is a global expert in vascular and stem cell biology and engineering, including pioneering engineering principles to understand and harness cell fate decisions for therapeutic developments. She and her lab team study how the microenvironment modulates stem cell fate, differentiation, and tissue assembly. These include understanding how various properties of the extracellular matrix modulate cellular responses and how oxygen gradients regulate tissue performance. They develop biomaterials to guide morphogenesis through sequential activation of signaling pathways to form functional tissues and use a range of disease and injury models to delineate these mechanisms in vivo. 

Dr. Gerecht is the recipient of the Allan C. Davis Medal from the Maryland Academy of Sciences (2008), the North America Vascular Biology Organization Junior Investigator Award (2009), the Basil O’Connor Starter Scholar Research Award from the March of Dimes Foundation (2009-2011), the National Scientist Development Award (2008-2012) and Established Investigator Award (2014-2019) both from the American Heart Association, the National Science Foundation CAREER award (2011-2016), the W.W. Smith Charitable Trust Heart award (2014-2017), and the JHU Inaugural President’s Frontier Award (2015). Dr. Gerecht is an elected Fellow of the American Institute for Medical and Biological Engineering (2016), an elected Member of the National Academy of Medicine (2019), and an elected fellow of the American Association for the Advancement of Sciences (2020) and the National Academy of Inventors (2020). She is the author of more than 170 papers, book chapters, and patents in her field.

Bria Macklin, PhD
Dr. Bria Macklin is a Postdoctoral Scholar at The Gladstone Institutes in the laboratory of Bruce Conklin. As an undergraduate Bria was a recipient of the National Institutes of Health Minority Access to Research Careers (NIH MARC) program at the North Carolina A&T State University, providing her the opportunity to jumpstart her academic research career. In her doctoral program, she worked in the laboratory of Dr. Sharon Gerecht utilizing stem cell-derived endothelial cells to study vascular regeneration in 3D environments. In addition to this work, Bria studied the role of hypoxia in the vascular regeneration of ischemic tissues. Dr. Macklin received an NIH Pre-doctoral F31 Fellowship to support this work. Dr. Macklin is also a recipient of the 2021 Siebel Scholar Award in Bioengineering, awarded annually for academic excellence and demonstrated to top students from the world’s leading graduate schools. As a postdoc, Bria now works on the development of therapeutic gene editing treatments for neurodegenerative diseases.
