1 · What the graph read from it

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.

2 · The registry

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

The most common treatment for people with people with type 1 diabetes (T1D) requires injections of exogenous insulin to regulate blood glucose homeostasis. A longer-term therapeutic solution for T1D has emerged whereby patients may regain insulin independence through transplantation of donated human pancreatic islets, which contain insulin-secreting beta (β)-cells. Donated islets, however, are in short supply. Much effort has been dedicated to using human pluripotent stem cell (hPSC)-derived islets (SC-islets) as an unlimited source of insulin-secreting β-cells. Here, we describe a robust and reproducible 40-day, seven-stage stepwise process for generating hPSC-derived SC-islets. Our differentiation protocol aims to mimic in vivo pancreas development using stage-specific signals to promote the generation of SC-islets. The initial maintenance and the first four stages are performed in two-dimensional monolayer culture; the subsequent three stages require three-dimensional culture in microwells to induce the formation of islet-like clusters. The SC-islets generated at the end of the procedure respond to glucose challenges, reliably express appropriate endocrine markers, contain intracellular insulin, and display an islet-like architecture. Most SC-islets also partially express maturity markers that are often challenging to activate in vitro. These protocols thus provide a scalable platform for generating SC-islets for disease modeling and cell replacement studies. © 2026 The Author(s).
