Tooth root development relies on precise coordination of cellular signals, yet the underlying mechanisms remain unclear. Researchers have uncovered how two proteins, Gli2 and Gli3, work together to ...

The retina is a thin layer of neural tissue at the back of the eye that detects light and converts it into signals, sent to the brain. During development, all the specialized neurons in the ...

A rare subtype of neuron from transplanted stem cells can reconnect spinal motor circuits and activate leg muscles after injury, offering new insight for spinal cord repair strategies, according to a ...

“During development and tissue regeneration, stem and progenitor cells give rise to differentiated cell types in defined numbers and proportions to properly generate and maintain organs and body plans ...

Researchers used miniature human brains grown in the lab to uncover why certain genetic mutations lead to abnormally small brains. Changes in actin disrupted the orientation of early brain cell ...

Researchers at the University of Pittsburgh have identified a novel trigger of a deadly form of ovarian cancer. Discovery of a subset of high-risk progenitor cells that reside in fallopian tube ...
