A Fruitful Pursuit: Plant Biology at Whitehead Institute

January 24, 2019

Decades of pioneering plant research at Whitehead Institute have led to biological insights and useful discoveries

Toxoplasma gondii (T. gondii) cells lose form and fail to replicate after degradation of GAPM proteins.

A Blueprint for Regeneration

March 15, 2018

Researchers at Whitehead Institute have uncovered a framework for regeneration that may explain and predict how stem cells in adult, regenerating tissue determine where to form replacement structures.

Small worm muscles up to reveal ancient body patterning mechanism during regeneration

October 30, 2017

Whitehead Member Peter Reddien has determined that a major function of muscle in planaria and acoels--a small regenerative marine worm auspiciously located on the evolutionary tree as an outgroup to all the rest of the Bilateria--is to serve as the source of instructive positional information for instructing regeneration.

Jaw-dropping research explains mouth formation during embryonic development

August 2, 2016

Whitehead Institute researchers have identified an area in the developing face of embryonic frogs that unzips to form the mouth. The scientists, who named this region the “pre-mouth array”, have also discovered the cellular signaling that triggers its formation. Elucidating this critical aspect of craniofacial development in a model organism enhances understanding of and potential treatment for human facial birth defects.
