Researchers have successfully regenerated functional bladder tissue in a baboon using the animal’s own bone marrow cells. With the organ working within a few months and staying healthy throughout the two-year study, the findings open the door to a novel treatment for severe bladder dysfunction for which treatment is currently limited.Certain conditions can affect the bladder, including spina bifida, spinal cord injuries, and malignancy, resulting in urine leakage, bladder stiffness, and loss of bladder capacity.

Researchers have taken a big step forward in the quest to regenerate the pancreatic beta-cells damaged by type 1 diabetes. Using FDA-approved drugs usually given to patients with rare cancers, they reprogrammed pancreatic cells to produce and secrete insulin in response to glucose. The discovery could mean that, one day, diabetics won't need to take multiple daily insulin injections.Pancreatic beta-cells synthesize, store and release insulin. But, in type 1 diabetes (T1D), the immune system selectively destroys these…
