Summary (written by the submitters)
It has been postulated that during human fetal development all cells of the lung epithelium derive from an embryonic endodermal NKX2-1+ precursor, however, this hypothesis has not been formally tested due to an inability to purify or track this theorized cell for detailed characterization. Here we engineer and developmentally differentiate NKX2-1GFP reporter pluripotent stem cells (PSCs) in vitro to generate and isolate a human primordial lung progenitor that expresses NKX2-1 but is initially devoid of markers of differentiated lung lineages.

As these progenitors move through the earliest moments of lung lineage specification from definitive endoderm they can be imaged in real time or isolated for time-series global transcriptomic profiling. We performed microarray analysis of 5 timepoints of human iPSC to lung directed differentiation compared to week 21 human fetal lung and Neural NKX2-1+ cell controls. These profiles indicate that evolutionarily conserved, stage-dependent developmental gene signatures are expressed in primordial human lung progenitors. Using a TALEN-targeted fluorescent reporter to purify iPSC-derived lung progenitors (C17 NKX2-1GFP) we analyzed cells at major developmental time points in vitro (undifferentiated iPSC, definitive endoderm, anterior foregut endoderm and sorted NKX2-1GFP+ and NKX2-1GFP- cells on day 15 and day 28 of the protocol). We also differentiated NXK2-1GFP iPSC in a neural protocol and isolated neural NKX2-1GFP+ cells. Approximately 90% pure human fetal lung epithelial cells from week 21 embryos were used as controls.

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.

Supports a between-group comparison across 26 samples.

How we read this: 9 replicated groups read from 27 sample titles; they account for 26 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
