Note the extensive arborisations of the indicated ( red arrowhead) astrocyte ( I assume). The cytoplasm is not positive. Sure, many of the top R and L processes are most likely other cells’.
Also note the intimacy with the neurone ( blue cytoplasm, unstained nucleus, excepting the nucleolus).
Lateral ventricle: intense positivity in svz cells ( appears to be nuclear and cytoplasmic: ependymal cells most obviously show the nuclear positivity)
