Blood vessels originating from lymphatic vessels were found to be tailored to specific functions. (israelnationalnews.com)
In the new study, postdoctoral fellow Dr. Rudra N. Das, working in Yaniv's lab in the Immunology and Regenerative Biology Department, discovered that blood vessels can develop from a previously unknown source: lymphatic vessels. (israelnationalnews.com)
It was known that blood vessels can give rise to lymphatic vessels, but we've shown for the first time that the reverse process can also take place in the course of normal development and growth," Das says. (israelnationalnews.com)
By tracing the growth of fins on the body of a juvenile zebrafish, Das saw that even before the bones had formed, the first structures to emerge in a fin were lymphatic vessels. (israelnationalnews.com)
Das and colleagues provided an explanation by analyzing mutant zebrafish that lacked lymphatic vessels. (israelnationalnews.com)
They found that when lymphatic vessels were absent, the blood vessels did sprout in the growing fins of these mutants by branching from existing, nearby blood vessels. (israelnationalnews.com)
In other words, only those blood vessels that had matured from lymphatic vessels were perfectly suited to their specialized function - in this case, proper fin development. (israelnationalnews.com)
They saw that the entire process they had observed during the fins' development repeated itself during its regeneration - namely, lymphatic vessels grew first, and only later did they transform into blood vessels. (israelnationalnews.com)
