UT Southwestern researchers discover method of postponing labor in mice

Researchers at UT Southwestern discovered that administering the drug trichostatin A can effectively delay the start of labor in mice by allowing progesterone to continue functioning. This is significant because mice have a short gestation period, and pre-term birth affects over 460,000 infants annually.

ES cell model could provide clues to causes, cures for diabetes

Researchers have developed a mouse embryonic stem cell model that can differentiate into pancreatic precursor cells and islet cells producing four types of hormones. This study could provide valuable insights into normal pancreatic development and potentially lead to better stem cell-based therapies for diabetes.
