Single Lgr5 Stem Cell Culture to Generate Crypt-Villus Organoids
Source Sato et al., 2009 · Hubrecht Institute and University Medical Center Utrecht · 10.1038/nature07935
Abstract
This protocol establishes long-term in vitro culture of intestinal crypt-villus organoids from single mouse Lgr5+ stem cells embedded in Matrigel under defined growth factor conditions. The organoids self-organize to form functional crypt domains with stem cells and Paneth cells at the base, and villus-like epithelial structures with all differentiated intestinal cell types, without requiring mesenchymal niche cells.
Protocol overview
29 steps across 5 phases
- 1 Intestinal tissue preparation
- 2 EDTA incubation to dissociate tissue
- 3 Mechanical dissociation to separate crypts
- 4 Filtration to remove villous material
- 5 Separation of crypts from single cells
- 6 Count isolated crypts
- 1 Mix crypts with Matrigel
- 2 Allow Matrigel to polymerize
- 3 Add culture medium with growth factors
- 4 Culture crypts at 37°C
- 5 Change medium every 4 days
- 6 Observe crypt growth milestones
- 1 Remove organoids from Matrigel
- 2 Dissociate organoids into single-crypt domains
- 3 Plate at 1:5 split ratio
- 4 Resume standard culture protocol
- 1 Prepare single-cell suspension from crypts
- 2 Filter to remove cell clumps
- 3 Sort Lgr5-GFP+ cells by flow cytometry
- 4 Collect sorted cells in culture medium
- 5 Embed single cells in Matrigel with Notch agonist and ROCK inhibitor
- 6 Add culture medium with Y-27632
- 7 Culture single cells at 37°C
- 8 Add growth factors every other day
- 9 Change entire medium every 4 days after initial week
- 1 Prepare tamoxifen solution
- 2 Incubate crypts or organoids with tamoxifen
- 3 Replace with regular culture medium
- 4 Image and document lineage tracing
