Selective Pericyte Recruitment To Ec-Lined Tubes, Vessel Assembly Enhancement Through Pericyte Timp-3 Induction, And Pericyte Tbx2 In Capillary Formation And Maturation, Ksenia Marilyn Yrigoin Kaluguina

USF Tampa Graduate Theses and Dissertations

Capillaries, the smallest blood vascular networks, are formed by narrow and elongated endothelial cell (EC)-lined tubes with associated pericytes anchored to the abluminal tube surface. Our laboratory demonstrated that dynamic interactions between ECs and pericytes during capillary tube network assembly are required for basement membrane matrix deposition and maturation. We have also shown that key EC-derived factors promote pericyte recruitment, proliferation, and pericyte-induced basement membrane formation during capillary assembly. In the first section, we aim to identify if vascular smooth muscle cells (VSMCs) respond to the same factors and have the same invasive ability as pericytes since they are both …

Rictor, A Mtorc2 Protein, Regulates Lymphatic Valve Formation And Maintenance Through The Akt-Foxo1 Signaling Axis, Richa Banerjee

USF Tampa Graduate Theses and Dissertations

The lymphatic vasculature maintains tissue fluid homeostasis by absorbing interstitial fluid to form lymph and transporting it back to the bloodstream. Collecting lymphatic vessels have lymphatic valves (LVs) that prevent the retrograde flow of lymph generated by hydrostatic pressure from the blood vasculature. Backflow and accumulation of lymph leads to a lymphatic pathology called lymphedema. This implicates the involvement of defective LVs in the pathogenesis of lymphedema and warrants the study of lymphatic valve development and maintenance. The LVs are formed through a process called mechanotransduction which signals through the intracellular PI3K-AKT pathway in lymphatic endothelial cells. However, the activation …
