Although the data regarding presence of absence of VEGF receptors on the cellular membrane of fibroblast-like cells in CNV is missing, other studies have shown VEGF receptor presence on joint fibroblasts extracted from humans as well as expression of VEGF by inflammatory stimulation of fibroblast-like cells that infiltrate the joint in a collagen-induced arthritis [15]. This evidence concerns the gene VEGFA and arthritic joint disease.
