| Source name |
small intestinal crypts
|
| Organism |
Mus musculus |
| Characteristics |
tissue: small intestinal crypts
strain/genotype: Tg(Vil1-cre/ERT2); Ctnnb1-D164A/flox
days post cre induction: 0
background strain: C57BL/6
|
| Treatment protocol |
To induce Cre-ERT2-mediated recombination, tamoxifen (Sigma, 80 mg/kg) was injected intraperitoneally on two consecutive days. Mice were sacrificed 48 hours after the first tamoxifen injection. Alternatively, mice were injected on 4 consecutive days and sacrificed 96 hours after the first injection.
|
| Growth protocol |
All animals were kept on a C57BL/6 background. Mice were 8-12 weeks old at the time of treatments and cell isolations. Mice of both sexes were used in all experiments and littermates were used as controls.

| Extraction protocol |
Control (n=3) and D164A (n=3) mice were sacrificed 0, 2 or 4d post injection, crypts were isolated as described (Sato and Clevers, 2013). Crypt fractions 3 and 4 were pooled and dissociated to single cells by incubating them with 5 mL pre-warmed TripLE Express Enzyme (ThermoFischer) in a 37 °C water bath for 5 min with frequent agitation. TripLE was inactivated with 50% FBS in Advanced DMEM/F12 (ThermoFischer). Single cells were pelleted at 180 g for 3 min and resuspended in 2 mL cold Intesticult (Stemcell Technologies Inc). Clumps were dissolved by pipetting up and down with a 1mL pipet before filtering twice through a 40 micron filter. Cell viability and number were quantified in automatically with a Countess (Thermo Scientific).
DropSeq workflow was performed as described (Macosko et al, 2015) on a Nadia Instrument (Dolomite Bio). Sequencing was performed on the Illumina NovaSeq6000 with an SP Reagent Kit.
