RNA-seq of wildtype mouse small intestinal organoids grown in Matrigel or in/on collagen.

We aimed to analyse the effect of different extra-cellular matrices on the growth of small intestinal organoids. Small intestinal crypts of wildtype mice were harvested and grown under standard Matrigel organoid conditions. After establishment of organoids (passaged 1-2), organoids were grown in Matrigel, on collagen or in a drop of collagen. Growth in a droplet of collagen requires addition of Wnt3a, therefore all samples are either provided with standard culture conditions (ENR) or with ENR+50%Wnt3a-CM (WENR). Samples were grown in specified matrix for at least 1-2 passages before RNA was purified.
