Indeed, he showed the yet-seen Dönmez study [16], plus the study by Chen et al. [29] (11 points out of 20), where the mucosa and submucosa thickness, the proliferation of normal human fibroblast cells (HFCs), the intervals between micturition, plus the expression of cell junction-associated protein zonula occludens 2 (ZO-2) and of the interleukin-6 (IL-6) was assessed to evaluate the efficacy of intravesical instillation with PRP and/or hyaluronic acid (HA) in mouse models of CYP-induced cystitis. This evidence concerns the gene TJP2 and chronic cystitis.
