Spatially organized in vitro models instruct asymmetric stem cell differentiation

Abstract

Understanding developmental biology requires knowledge of both the environmental factors regulating stem cell differentiation, which are increasingly being defined, and their spatial organization within a structurally heterogeneous niche, which is still largely unknown. Here we introduce spatially organized stem cell developmental models to interrogate the role of space in fate specification. Specifically, we developed Differential Environmental Spatial Patterning (δESP) to organize different microenvironments around single embryonic stem cell (ESC) colonies via sequential micropatterning. We first used δESP to decouple and understand the roles of cell organization and niche organization on ESCs deciding between self-renewal and differentiation fate choices. We then approximated in vitro an embryonic developmental step, specifically proximal-distal (PD) patterning of the mouse epiblast at pre-gastrulation, by spatially organizing two extraembryonic environments around ESCs, demonstrating that spatial organization of these three cell types is sufficient for PD patterns to form in vitro.

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.
