There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Role of Mechanical Microenvironment on the Regulation of Lymphatic Function and Health
Failure of lymph fluid transport plays an important role in pathologies, such as lymphedema and lymphacele after organ donation. The lymphatic system plays a critical role in maintaining fluid homeostasis in all of the soft tissue of the body. Its ability to transport interstitial fluid is partially dependent on the intrinsic pumping capacity of lymphatic smooth muscle cells. Recently, our lab has shown that lymphatic collecting vessels near an injury never return to pre-injury levels of pumping and lymph transport, but factors that impact collecting vessel phenotype are poorly understood. The central hypothesis of this work is that the components of the extracellular matrix (ECM) and mechanics of the lymphatic microenvironment play a central role in the contractile phenotype of lymphatic muscle cells (LMCs).
