The immediate astroglial cell destruction caused by the expanding hematoma is assumed to be responsible for the rapid GFAP release into the intravasal blood in acute ICH (8).
This ependymal loss appears much earlier than the increase of intracranial pressure and the ventriculomegaly and is therefore the first recognizable event in hydrocephalus pathology, and this is accompanied by a microglial and astroglial cell reaction; the subependymal astroglial cells respond by proliferation in such a way that they form a glial scar-like covering of the ventricular surface to replace the ependymal epithelium [12, 13].
Several researchers have reported the production of members of the neurotrophin family such as NGF, BDNF, and neurotrophin-3 in the cultured astroglial cell lines (Moretto et al.
