Asymmetric cell divisions promote Notch-dependent epidermal differentiation
Open accessAbstract
Stem and progenitor cells use asymmetric cell divisions to balance proliferation and differentiation. Evidence from invertebrates shows that this process is regulated by proteins asymmetrically distributed at the cell cortex during mitosis: Par3-Par6-aPKC, which confer polarity, and Gα(i)-LGN/AGS3-NuMA-dynein/dynactin, which govern spindle positioning. Here we focus on developing mouse skin, where progenitor cells execute a switch from symmetric to predominantly asymmetric divisions concomitant with stratification. Using in vivo skin-specific lentiviral RNA interference, we investigate spindle orientation regulation and provide direct evidence that LGN (also called Gpsm2), NuMA and dynactin (Dctn1) are involved. In compromising asymmetric cell divisions, we uncover profound defects in stratification, differentiation and barrier formation, and implicate Notch signalling as an important effector. Our study demonstrates the efficacy of applying RNA interference in vivo to mammalian systems, and the ease of uncovering complex genetic interactions, here to gain insights into how changes in spindle orientation are coupled to establishing proper tissue architecture during skin development.

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.
