Phenotypic fidelity
WebGliomas are intensely heterogenous tumors that not only contain numerous cell types, but also demonstrate the ability to transition between different phenotypic states. This complexity has made developing model systems that recapitulate human tumor biology both difficult and essential. WebNov 29, 2011 · While such gain-of-function experiments reveal the potential of adult cells to change fates, they do not address the mechanisms by which lineages normally maintain phenotypic fidelity. Here, we provide evidence that an endogenous signaling pathway acts to prevent cell type interconversion in the adult pancreas.
