Other growth factors that signal through receptor tyrosine kinases like IGFs were also downregulated in COVID‐19, including vascular endothelial growth factors (VEGF‐A, VEGF‐B and VEGF‐C), several fibroblast growth factor (FGF) isotypes and colony stimulating factor‐1 (CSF‐1). This evidence concerns the gene CSF1 and COVID-19.
