STELLA subpopulations identified by gene product localization

XPS/ACD	STELLA/OCT/PRDM1¹ STELLA/(OCT)/(PRDM1)/T²
aPVE	STELLA/OCT/PRDM1¹ STELLA/OCT
Hindgut Lip/ Hindgut	STELLA/OCT/PRDM1¹ STELLA/OCT STELLA/OCT/FOXa2³ STELLA/OCT/Runx1
Other possible, but not yet proven, combinations⁴	STELLA/OCT/PRDM1/Runx1 STELLA/OCT/FOXa2/PRDM1 STELLA/OCT-3/4/FOXa2/Runx1 STELLA/OCT-3/4/FOXa2/PRDM1/Runx1

Together with data in this study, we conclude that a STELLA/OCT/PRDM1 population is found in all putative PGC tissues (Mikedis and Downs, 2017).

STELLA invariably co-localized with PRDM1 in the allantoic component of the primitive streak (Mikedis and Downs, 2017) and co-localized in this study with T in just 3 cells in one late headfold-stage specimen.

STELLA/OCT/Foxa2 were found only in the hindgut lip, and not within the hindgut itself in this study.

These possible combinations are based on results here combined with those of previous studies (Mikedis and Downs, 2012, 2017).
