New molecule blocks lymphangiogenesis

Researchers in the laboratory of Dr. Jayakrishna Ambati at the University of Kentucky have discovered the first naturally occurring molecule that selectively blocks lymphatic vessel growth. In an article in the Aug. 9, 2009 online edition of Nature Medicine, they report the identification of a new molecule known as soluble VEGFR-2 that blocks lymphangiogenesis - the growth of lymphatics - but not blood vessel growth.

NIH stimulus funding supports Emory - grants to advance research, create jobs, support students

At least 50 research projects so far, supported by more than $10 million in stimulus grants from the National Institutes of Health, are expected to lead to new discoveries at Emory University that will improve medical treatment, create new jobs, and provide additional educational opportunities for students. Emory has received half of all the NIH ARRA grants awarded to Georgia academic institutions thus far.

Model for new generation of blood vessels challenged

In-growth and new generation of blood vessels, which must take place if a wound is to heal or a tumor is to grow, have been thought to occur through a branching and further growth of a vessel against a chemical gradient of growth factors. Now a research team at Uppsala University and its University Hospital has shown that mechanical forces are considerably more important than was previously thought.
