Bladder cells are from a hollow organ in the pelvis with flexible, muscular walls. Its main function is to store urine before it leaves the body. Urine is made by the kidneys and is then carried to the bladder through tubes called ureters. However when the bladder cells start to grow uncontrollably, the bladder cancer begins. Several types of cancer can start in the bladder and the most common one is the urothelial cancer. Creative Bioarray can offer different types of bladder cells which are isolated from human bladder tissue, including human bladder microvascular endothelial cells, human bladder epithelial cells, human bladder fibroblasts, human bladder smooth muscle cells, etc. Human bladder cells may be used for various types of in vitro, in vivo, or medicine studies in normal or diseased systems.
