The niche signal that ensures stem cells self-renew appropriately has been identified in the midgut of Drosophila.

The intestine contains distinct subregions specialized for digestion along its anterior-posterior axis, and the stem cells that constantly renew these subregions are not interchangeable.

The loss of genes that encode RNA splicing factors weakens cancer cells in a way that could be exploited by new approaches to treatment.

The Brahma chromatin remodelling complex interacts with the Hippo signalling pathway to regulate the proliferation and differentiation of stem cells in the Drosophila midgut.

Ploidy-increasing endocycles may represent a tradeoff between loss of regenerative capacity and preservation of tissue architecture.

In response to tissue damage, reactive oxygen species can be sensed by cation channels TRPA1/RyR to cause increases of cytosolic Ca²⁺ in intestinal stem cells, activating Ras/MAPK activity and stimulating stem cell proliferation in Drosophila.

Being able to take up DNA from their environment might allow pneumococcal bacteria to colonize the human nose and throat for longer periods of time.
