Popular Science reports on new artificial bladders made by a company named Tengion. The bladders are grown on biodegradable scaffolds using the patient's own cells, collected via a biopsy from the patients natural bladder.
According to the report, the neo-bladders created and implanted during their testing, after re-implantation, grew to the same size as the original bladders and functioned effectively. The company hopes to start clinical trials in 2009.
Hopefully the company will be able to extend this technology effectively to other organs, allowing the growing of replacement organs for which people currently have to spend time on a waiting list for donors.
