On the basis of these results, IL-6 and VEGF proteins were evaluated by IHC or HE in a group of patients confirming the difference detected by gene expression between ACL (n = 21) and OA IFP (n = 14) (Figure 2b,c,e,f) (Table S3, Supplementary Materials). The gene discussed is VEGFA; the disease is hereditary elliptocytosis.
