In this article, we review the origin and therapeutic perspectives of bladder cancer stem cells (BCSCs), which are integral to the initiation, high recurrence and chemoresistance of bladder cancer. BCSCs are heterogenous and originate from multiple cell types, including urothelial stem cells and differentiated cell types, including basal, intermediate stratum and umbrella cells. Cell surface markers, including CD44, CD67LR, EMA, ALDH1A1 and BCMab1, are used to identify and isolate BCSCs. The Hedgehog, Notch, Wnt and JAK-STAT signaling pathways play key roles in maintaining the stemness, self-renewal and proliferative potential of BCSCs. High expression of ABC transporters, acetaldehyde dehydrogenase, antioxidants and apoptosis resistance proteins in BCSCs play a critical role in chemoresistance. Consequently, a greater understanding of the biology of BCSCs will be important for identifying effective therapeutic targets to improve clinical outcomes for bladder cancer patients.

Three Janus kinase (JAK) inhibitors, ruxolitinib, tofacitinib, and baricitinib, are currently approved by the FDA/EMA for the treatment of rheumatoid arthritis, psoriatic arthritis, and ulcerative rectocolitis. The inhibition of JAK/STAT signaling by these small molecules, downstream of several cytokine receptors, results in lower pro-inflammatory gene expression. Given the cytokine profiles observed in rheumatologic diseases, most of the recent therapeutic strategies target cytokines, either directly or through their receptors. Each cytokine receptor recruits a specific combination of JAKs to activate different programs in cells. The approved drugs are panJAK inhibitors, able to impede more than one pathway. These drugs are being tested in various rheumatologic disorders. At the same time, more specific molecules able to target one specific JAK are being developed. In this review, we describe the expanding spectrum of rheumatologic and autoimmune conditions for which JAK inhibition may represent new avenues in clinical practice.
