Article Title: The Fatty Acid Transporter CD36 Mediates Uptake, Biodistribution, and Cardioprotection by Small Extracellular Vesicles From HEK293 Cells

doi: 10.1002/jev2.70254

Figure Lengend Snippet: Dose‐response and time‐response uptake of HEK293‐sEVs in human endothelial cells and cardiomyocytes. (A–C) Human coronary artery and coronary microvascular endothelial cells (HCAEC and HCMEC respectively) and human umbilical vein endothelial cells (HUVEC) were treated for 4 h with increasing doses of HEK293‐sEVs. A linear dose‐response was revealed in all endothelial cells, as a 10‐fold increase of sEVs dose results in a 10‐fold increase of cellular uptake (Nluc Nanoluciferase activity). (D–F) sEVs rapidly internalise endothelial cells ((D) HCAEC, (E) HCMEC, and (F) HUVEC) within the first hour of incubation reaching the highest intracellular localisation after 4 h, corresponding to higher Nluc activity. A reduction in luciferase activity after 24 h is observed in all endothelial cells, reflective of the reduced amount of sEVs intracellularly. (G) Uptake of HEK293‐sEVs in adult rat cardiomyocytes is slow and time‐dependent, and high Nluc activity is recorded only after 24 h of sEVs incubation. Data shown as mean ± SEM ( n = 4). * p < 0.05, ** p < 0.01, **** p < 0.0001.
