In this study, immobilized VEGF selectively captured endothelial cells under various shear stresses, suggesting its potential for promoting endothelialization in vascular grafts or implanted tissues.

This review discusses the various skin lesions associated with COVID-19, which vary in type and severity, and reports that these lesions can appear before other symptoms and typically resolve spontaneously.

This study suggests that T-cell recruitment, thrombosis, and increased vascular permeability may contribute to various symptom clusters in post-acute sequelae of COVID-19 through shared cytokine elevation.
