Table 1. Cell populations immunolabeled and collected by FACS from human fetal cortex for RNA-seq analysis.
Dissociated fetal human cortical tissue was immunolabeled for radial glial progenitor markers LeX (CD15), GLAST (SLC1A3), and PROM1 (Prominin; CD133). LeX and Glast are detected on the vast majority of radial glial cells16–18, while Prom1 is specific to the apical membrane domain found at the ventricular surface19,20.
| Sorted Pool | Antigenicity | Enriched Markers (qRT-PCR) | Cell Type |
|---|---|---|---|
| LG+Prhi | LeX+, Glast+, Prom1-high | PAX6, SOX2, VIM, NES, BLBP, PARD3 (PAR3), TJP1 (ZO1), MPP5 (PALS) | apical radial glial cells |
| LG+Prlo | LeX+, Glast+, Prom1-low | PAX6, SOX2, VIM, NES, BLBP | non-apical radial glial cells, including ORG |
| LG−Pr− | LeX−, Glast−, Prom1− | TUJ1, DCX, MEF2C, NEUN | intermediate progenitors, neurons |
