Mus musculus |
| Characteristics |
cell type: sorted primary pancreatic epithelial cells (mKate2+)
tissue: pancreas
condition: K4
model: KC;RIK
alleles: p48Cre;RIK;LSL-KrasG12D
treatment: n/a

time point_(analyses): 27 weeks old
Sex: Male
|
| Treatment protocol |
Pancretata were harvested from the indicated mouse models and processed for FACS sorting using Collagenase (1 mg/mL) & Dispase (2 U/mL) mix digestion solution and Gentle-MACS dissociator (mTDK_1 protocol), followed by a 0.05% Trypsin-EDTA step. Cell suspensions were incubated with Fc block and CD45-APC or CD45-APC-Cy7 antibody to mark immune cells. Live pancreatic epithelial cells (marked as mKate2-positive, CD45-negative and DAPI-negative) or immune cells (marked as mKate2-negative, CD45-positive and DAPI-negative) were sorted using Aria3 or Aria 1 sorter, and collected in 2% 1x PBS buffer containing 2% fetal bovine serum (FBS). Single-cell suspensions were spun down and resuspended in 0.05% BSA containing 1 U/µL Invitrogen Ambion RNase Inhibitor (AM2682, Thermo Fisher Scientific).

| Growth protocol |
When indicated, 5 weeks-old KC;RIK (p48-Cre;RIK;LSLKrasG12D) littermate male mice were treated with 8 hourly intraperitoneal injections of 80 μg/kg caerulein (Bachem) for 2 consecutive days.

| Extraction protocol |
Single-cell encapsulation and scRNA-seq library prep of FACS-sorted cell suspensions was performed on the Chromium instrument (10x Genomics) following the user manual (Reagent Kit 3’ v2). Each sample loaded onto the cartridge contained approximately 5,000 cells at a final dilution of ~500 cells/μl. Transcriptomes of encapsulated cells were barcoded during reverse transcription.
cDNA was purified with DynaBeads, followed by amplification per the user manual (Reagent Kit 3’ v2). Next, the PCR-amplified product was fragmented, A-tailed, purified with 1.2X SPRI beads, ligated to sequencing adapters and indexed by PCR. Indexed DNA libraries were double-size purified (0.6–0.8X) with SPRI beads.
