RNA-seq of small intestinal organoids treated with the control medium ENR (EGF, Noggin, R-spondin1) in the presence or absence of muscle supernatant. RNA-seq of small intestinal organoids treated with the control medium ENR (EGF, Noggin, R-spondin1) in the presence or absence of muscle supernatant

In order to unravel the impact of intestinal smooth muscle tissue on the intestinal epithelium, we isolated clean smooth muscle, cultured it for 24h in DMEM-F12, and collected the supernatant (muscle-SN). This supernatant was used to treat small intestinal organoids (made of intestinal epithelium), compared to normal ENR treatment. After 5 days of muscle-SN exposure, we disrupted the organoids, and directly isolate the RNA. RNA-seq was performed in this sample to assess the genetic changes induced by muscle products.
