Regrowing dental tissue with stem cells from baby teeth

In a clinical trial led by Songtao Shi of the School of Dental Medicine, stem cells extracted from baby teeth were used to regrow the living tissue in teeth damaged by injury. The promising findings highlight the potential of dental stem cells, which could be used in a wide range of dental procedures, or treating certain systemic diseases.

Knockdown and replace: A gene therapy twofer to treat blindness

More than 150 different mutations in the light-sensing molecule rhodopsin can cause retinitis pigmentosa, characterized by a progressive loss of night and peripheral vision, and a team of researchers have developed a treatment for the condition. Successful results in dogs set the stage for testing in humans.
