11th season of the Fralin Biomedical Research Institute’s Pioneers in Biomedical Research Seminar Series launches Sept. 16

With topics ranging from addiction recovery to stem cell therapies, the Fralin Biomedical Research Institute at VTC launches the 11th season of its Pioneers in Biomedical Research Seminar Series on Sept. 16.

The full slate features 29 experts sharing leading discoveries in cardiovascular science, cancer research, neuroscience, biomedical imaging, addiction, and health behaviors. 

The seminars are selected to be of particular interest to members of the Virginia Tech and Carilion Clinic communities, including graduate and medical students, undergraduates, faculty, and staff. The lecture series is divided into fall and spring seasons, with the first 10 scheduled from September through December, and will be held in-person at the Fralin Biomedical Research Institute. In addition, the lectures can be attended virtually through the research institute’s website...more

Congratulations to grad student (now postdoc!) Yinyu Wu for her successful thesis defense on regulation of hemogenic endothelial cell specification by microRNA-223.  Yinyu traveled back to Yale to attend her graduation.

Hirschi, Alumni Professor of Cell Biology, is an internationally respected vascular biologist using a variety of cellular, molecular and genomic approaches to study the development and regeneration of blood vessels and blood cells in animal and human stem cell models. 

The goal is to identify candidate gene mutations that cause vascular and blood cell developmental disorders, Hirschi wrote in email. Her lab is analyzing genetic data from affected patients and their parents, and will screen candidate genetic mutations in human stem cell and animal models to determine which cause defects in the development of organs and systems in utero.

Part of her research, focused on personalized medicine, involves partnerships with clinical scientists and bioinformaticians at UVA, nonprofit health care provider Inova and the National Institute of Child Health and Human Development...more

As scientists study blood disorders and conditions, such as sickle cell disease and leukemia, they examine underlying processes involved in how blood and blood vessels form. In a research article in Science, scientists identified a pathway involved in the early production of blood cells. Formative processes for blood cell production that starts with cells that line the walls of blood vessels were known, but underlying mechanisms needed clarification. The researchers note this information provides the foundation to further study the formation of human blood stem cells in the lab.

“We hope our continued efforts will move us closer to treating both vascular and blood disorders,” study author Karen K. Hirschi, Ph.D., said in a release shared by the University of Virginia Health System. Hirschi published a second paper about this research in Cell Reports. The research was supported by the NHLBI.

Pioneering research into how our bodies manufacture the cells that make blood has moved us closer to regrowing tissues and organs. The findings also may let doctors grow cells for transplantation into people to battle cancer, blood disorders and autoimmune diseases.

Researcher Karen K. Hirschi of the University of Virginia’s Department of Cell Biology and Robert M. Berne Cardiovascular Research Center at the School of Medicine has developed a simple and efficient way to generate hemogenic endothelial cells. These cells are the first step in the production line of blood cells, and Hirschi’s new findings provide a blueprint for creating them outside the body...more

CHARLOTTESVILLE, Va. (CBS19 NEWS) -- A discovery by University of Virginia Health System researchers could move doctors closer to regrowing tissue or other organs affected by the disease.  Researchers are making efforts to generate a specific type of cell faster and outside of the body.
These cells, called Hemogenic Endothelial cells, are the first step in the production line of blood cells. That opens doors for treating certain types of cells.  Endothelial cells are typically taken from an individual’s bone marrow, but now doctors want to be able to manufacture them quicker and easier for patients on demand.  “Our ultimate goal is trying to make human vascular blood cells so that they can be used to treat patients that need organ and tissue replacements, or for patients that are battling blood cancers,” said UVA’s Department of Cell Biology and Cardiovascular Research Center Dr. Karen Hirschi...more

 

A sugary coating tells cells it’s time to make blood
Nature Research Highlights - December 3, 2020

A ‘sugar code’ on the cells that pave the inside of blood vessels plays an important part in the formation of blood during an embryo’s development.

As an embryo develops, some of the endothelial cells that line the blood vessels are transformed into stem cells that will produce blood throughout an animal’s life. To understand this transformation, Karen Hirschi and Stefania Nicoli at Yale University School of Medicine in New Haven, Connecticut, and their colleagues manipulated the genetics of zebrafish to identify a combination of sugars that sit on the surface of endothelial cells and help to control the cells’ fate...more
