Component
Duct-lining precursor cells
Duct-lining precursor cells. Species, exposure and limitations are retained in each linked claim.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
Where it participates (unsigned role)
GABA was identified as an inducer of alpha-to-beta-like cell conversion in vivo, this conversion induces alpha cell replacement mechanisms through the mobilization of duct-lining precursor cells that adopt an alpha cell identity prior to being converted into beta-like cells solely upon sustained GABA exposure, these neo-generated beta-like cells are functional and can repeatedly reverse chemically induced diabetes in vivo, and similarly the treatment of transplanted human islets with GABA results in a loss of alpha cells and a concomitant increase in beta-like cell counts suggestive of alpha-to-beta-like cell conversion processes also in humans.
