Molecular Time Signalling Controls Stem Cells During Brain's Development

Researchers at Karolinska Institutet in Sweden have succeeded in explaining how stem cells in the brain change to allow one type of stem cell to produce different cell types at different stages. In a study being published in the journal Neuron, researchers show that the signal molecule TGF-beta acts as a time signal that regulates the nerve stem cells' potential at different stages of the brain's development - knowledge that may be significant for future pharmaceutical development.
