Representative scanning electron microscopy Images. Surface images of fibrin on cultured human umbilical vein endothelial cells (HUVECs) that have been incubated with human plasma. Conditions top‐to‐bottom are healthy HUVECs, influenza A/Singapore/6/86‐infected HUVECs and SARS‐CoV‐2‐infected HUVECs. Conditions left to right are incubated with endothelial growth media‐2 (EGM‐2) (control), healthy child plasma, healthy adult plasma and vasculopathic adult plasma. All images are presented at 5000× magnification
