Elucidating The Role Of Hemodynamic Force In Regulating The Attachment Of Vascular Smooth Muscle Cells (Vsmcs) To Maturing Vessels During Mouse Embryonic Development, Israt Jahan
MSU Graduate Theses
Blood vessel maturation is characterized by the recruitment and attachment of vascular smooth muscle cells (vSMCs) around immature blood vessels, which ultimately form the tunica media. Improper maturation can lead to vascular birth defects ranging from minor birthmarks to lethal brain aneurysms. Previously, our lab demonstrated that hemodynamic force plays an important role to regulate vSMCs recruitment from neighboring low-flow to high-flow vessels followed by the attachment of these vSMCs to the high-flow vessels. To understand the reason for the preferred attachment of vSMCs to high-flow vessels, instead of low-flow vessels, I hypothesize that hemodynamic force modulates the expression of …

The Effect Of Hemodynamic Force On The Maturation Of Blood Vessels During Embryogenesis, Rachel Lee Padget
MSU Graduate Theses
Throughout embryonic development, blood vessels are derived from endothelial cells by way of vasculogenesis. During angiogenesis, vessels remodel to form a hierarchy of large-diameter arteries that branch into small-diameter capillaries. In this maturation, vessels respond to unidentified signaling events to become surrounded with an outer layer of vascular smooth muscle cells (vSMCs). This results in arteries that have a thick vSMC layer, veins that have a thin vSMC layer, and capillaries that have a very thin or absent vSMC layer. What remains to be determined is the cause of the thicker layer of vSMCs around proximal arteries. Previous studies …
