The intestinal epithelium is a particularly attractive biological adult model to study epigenetic mechanisms driving adult stem cell renewal and cell differentiation. Since epigenetic modifications are dynamic, we have developed an original ex vivo approach to study the expression and epigenetic profiles of key genes associated with either intestinal cell pluripotency or differentiation by isolating cryosections of the intestinal crypt-villus axis. Gene expression, DNA methylation and histone modifications were studied by qRT-PCR, methylation-specific PCR and micro-chromatin immunoprecipitation, respectively. Using this approach, it was possible to identify segment-specific methylation and chromatin profiles. We show that (i) expression of intestinal stem cell markers (Lgr5, Ascl2) exclusively in the crypt is associated with active histone marks, (ii) promoters of all pluripotency genes studied and transcription factors involved in intestinal cell fate (Cdx2) harbour a bivalent chromatin pattern in the crypts and (iii) expression of differentiation markers (Muc2, Sox9) along the crypt-villus axis is associated with DNA methylation. Hence, using an original model of cryosectioning along the crypt-villus axis that allows in situ detection of dynamic epigenetic modifications, we demonstrate that regulation of pluripotency and differentiation markers in healthy intestinal mucosa involves different and specific epigenetic mechanisms.
