STEM CELLS

An inflammatory switch for stem cell plasticity

Tissue-resident stem cells are capable of remarkable plasticity in areas of tissue damage, where inflammatory cells accumulate as part of the reparative response. A study in the lung now provides critical insight on how inflammatory signals alter cell-to-cell Notch signalling within the airway niche to drive stem cell plasticity.
