PAX6-dependent differentiation landscape of ocular surface epithelium via single-cell RNA sequencing in hiPSC-derived ocular developmental organoid.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
During eye development, surface ectoderm cells that express PAX6 differentiate into corneal, limbal and conjunctival epithelia. However, several aspects of this differentiation process -- such as the developmental origin of the limbal epithelium and the mechanisms that underlie PAX6-mediated lineage specification -- are not properly understood. To explore these issues, we used single-cell RNA sequencing to study ocular surface epithelial cells derived from human induced pluripotent stem cells. Our analysis reveals that the corneal and conjunctival epithelial cell lineages originate from the surface ectoderm, and that the conjunctival lineage contributes to limbal epithelial cell populations. We also show that primordial conjunctival epithelial cells express limbal epithelial markers before lineage bifurcation. Finally, the activity and expression of PAX6 are highest in corneal epithelial cells, followed by those of the limbal epithelium and conjunctival epithelium, suggesting that lineage-specific differentiation is regulated by levels of PAX6 activity. These findings provide deeper understanding of the early-stage human ocular surface development.
