Intestinal stem cells count to eight divisions to maintain cell ratios

TL;DR - Fly intestinal stem cells maintain cell-type ratios through a division-counting program: eight rounds produce absorptive cells, followed by one round producing secretory cells.

• The study examines stem-cell behavior in the fly gut.
• Division count determines which cell type is produced.
• The eight-to-one schedule preserves the balance between absorptive and secretory cells.
