IHC 12th gw

No ALDH1L1  and GFAP immunoreactivity was detected at 12 weeks of gestational age.

Olig2
The pattern of the Olig-2-immunoreactive cell distribution (for more information see Kharlamova et al., 2024). 





S100
The S100- immunoreactive cell distribution was restricted by the ventral telencephalon. First S100-immunoreactivity within the developing cortex  was demonstrated in the dorsal proliferative zone as early as 10–11 gestational week strictly in the ventral-lateral intermediate zone (and partly subventricular zone). All S100-cells were arranged properly interior in the intermediate zone and localized just under the cortical plate of the neocortex.  The dorsal part of the hemisphere wall was immunonegative .  Ventricular zone of both main proliferative zones—ventral ganglionic eminence and dorsal ventricular zone — demonstrated no S100-immunoreactivity  (Kharlamova et al., 2024). 


Sox9
The pattern of the Sox9-immunoreactive cell distribution (for more information see Kharlamova et al., 2024).
