Abstract
The lymphatic vasculature is important for skin biology as it maintains dermal fluid homeostasis. However, the molecular determinants of the form and function of the lymphatic vasculature in skin are poorly understood. Here, we explore the role of vascular endothelial growth factor-d (Vegf-d), a lymphangiogenic glycoprotein, in determining the form and function of the dermal lymphatic network, using Vegf-d-deficient mice. Initial lymphatic vessels in adult Vegf-d-deficient mice were significantly smaller than wild-type but collecting lymphatics were unaltered. The uptake/transport of dextran in initial lymphatics of Vegf-d-deficient mice was far less efficient, indicating compromised functio..
