Abstract

SUMMARY Functional modeling of many adult epithelia is limited by the difficulty of maintaining relevant stem cell populations in culture. Here, we show that dual inhibition of SMAD signaling pathways enables robust expansion of primary epithelial basal cell populations. We found that TGFβ/BMP/SMAD pathway signaling is strongly activated in luminal and suprabasal cells of several epithelia, but suppressed in p63+ basal cells. In airway epithelium, SMAD signaling promotes differentiation, and its inhibition leads to stem cell hyperplasia. Using dual SMAD inhibition in a feeder-free culture system we were able to expand airway basal stem cells from multiple species. Expanded cells can produce functional airway epithelium that is physiologically responsive to clinically relevant drugs such as CFTR modulators. This approach is effective for clonal expansion of single human cells and for basal cell populations from epithelial tissues from all three germ layers, and may therefore be broadly applicable for modeling of epithelia.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
