[HTML][HTML] Role of angiopoietin-2 in vascular physiology and pathophysiology

RG Akwii, MS Sajib, FT Zahra, CM Mikelis - Cells, 2019 - mdpi.com
Angiopoietins 1–4 (Ang1–4) represent an important family of growth factors, whose activities
are mediated through the tyrosine kinase receptors, Tie1 and Tie2. The best characterized …

[HTML][HTML] S1PR1 regulates the quiescence of lymphatic vessels by inhibiting laminar shear stress–dependent VEGF-C signaling

X Geng, K Yanagida, RG Akwii, D Choi, L Chen… - JCI insight, 2020 - ncbi.nlm.nih.gov
During the growth of lymphatic vessels (lymphangiogenesis), lymphatic endothelial cells (LECs)
at the growing front sprout by forming filopodia. Those tip cells are not exposed to …
