Answer

The transitional cell apical membrane of the bladder is coated with GAGs and proteoglycans. Disruption of this layer can lead to transmigration of urinary solutes across the mucosal surface, affecting nerves and muscles and potentially leading to pain. Thus, restoration of this layer remains a mainstay in treatment of IC/BPS. [14]
