Bipotential hepatic progenitor cells (HPCs) are recognized as making modest contributions to hepatocyte regeneration, though never credited with major liver repopulation. A new study in mice demonstrates HPCs can make a massive contribution to hepatocyte replacement, suggesting HPCs have the potential to be an effective cell therapy for liver failure.
Bariatric surgery is an effective weight-loss strategy and often results in remission of type 2 diabetes mellitus (T2DM); still, how this surgery affects T2DM is unknown. A new study suggests that fibroblast growth factor 19 and bile acids are involved in remission of T2DM after bariatric surgery.
