Summary (written by the submitters)

Human embryonic stem cells with a GFP reporter knock-in into the NKX2.1 locus were differentiated and purified by FACS sorting for global gene expression analysis. Directed differentiation from human pluripotent stem cells (hPSCs) has seen significant progress in recent years. Most differentiated populations, however, exhibit immature properties of an early embryonic stage, raising concerns about their ability to model and treat disease.

Here, we report the directed differentiation of hPSCs into medial ganglionic eminence (MGE)-like progenitors and their maturation into forebrain type interneurons. We find that early stage progenitors progress via a radial glial-like stem cell enriched in the human fetal brain. Both in vitro and post-transplantation into the rodent cortex, the MGE-like cells develop into GABAergic interneuron subtypes with mature physiological properties along a prolonged intrinsic timeline of up to seven months, mimicking endogenous human neural development. MGE-derived cortical interneuron deficiencies are implicated in a broad range of neurodevelopmental and degenerative disorders, highlighting the importance of these results for modeling human neural development and disease.

3 · The original raw files

Whole study · RAW.tar

Everything the authors deposited as one archive (GSE45660_RAW.tar), including the raw array or instrument files. Can be large; the picker in step 2 takes just the samples you need.

Whole study · RAW.tar ↓

What the files usually look like: For arrays the series matrix is normally the normalised expression table you want; the raw array files (CEL and similar) are in the RAW.tar.
