Do tumours arise from stem cells, or are they derived from more differentiated cells that, for some reason, begin to recapitulate developmental programmes? Inappropriate activation of the Sonic hedgehog–Gli signalling pathway occurs in several types of tumour, including those of the brain and the ...
