Isolation and culture of mouse intestinal epithelial cells
After digestion with type I collagenase and hyaluronidase for
30 min, the small intestinal crypts were successfully isolated from
tissue samples (Figure 1A). Viability studies using dye exclusion
showed that 95% of the cells in the isolated crypts were viable.
Most crypts became adherent to the flask within 24 h, and a few
cells gradually migrated out around the crypts at 24 h (Figure 1B).
Then, the cells continued to divide extensively after culturing for 2
to 9 days (Figure 1C) before they reached confluence (Figure 1D).
