Description:
Stem cells of the gastrointestinal tract, pancreas, liver and other columnar epithelia collectively resist cloning in their elemental states. Here we demonstrate the cloning and propagation of highly clonogenic, 'ground state' stem cells of the human intestine and colon. We show that derived stem-cell pedigrees sustain limited copy number and sequence variation despite extensive serial passaging and display exquisitely precise, cell-autonomous commitment to epithelial differentiation consistent with their origins along the intestinal tract. This developmentally patterned and epigenetically maintained commitment of stem cells is likely to enforce the functional specificity of the adult intestinal tract. Using clonally derived colonic epithelia, we show that toxins A or B of the enteric pathogen Clostridium difficile recapitulate the salient features of pseudomembranous colitis. The stability of the epigenetic commitment programs of these stem cells, coupled with their unlimited replicative expansion and maintained clonogenicity, suggests certain advantages for their use in disease modelling and regenerative medicine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Xia -- Yamamoto, Yusuke -- Wilson, Lane H -- Zhang, Ting -- Howitt, Brooke E -- Farrow, Melissa A -- Kern, Florian -- Ning, Gang -- Hong, Yue -- Khor, Chiea Chuen -- Chevalier, Benoit -- Bertrand, Denis -- Wu, Lingyan -- Nagarajan, Niranjan -- Sylvester, Francisco A -- Hyams, Jeffrey S -- Devers, Thomas -- Bronson, Roderick -- Lacy, D Borden -- Ho, Khek Yu -- Crum, Christopher P -- McKeon, Frank -- Xian, Wa -- AI09575504/AI/NIAID NIH HHS/ -- R01 AI095755/AI/NIAID NIH HHS/ -- England -- Nature. 2015 Jun 11;522(7555):173-8. doi: 10.1038/nature14484.
