positive staining for this protein was seen in cells and fibres of all layers as they differentiated and could still be identified in some mature neurons at 120 days . alpha-fetoprotein and albumin had a limited distribution , appearing in cells in the developing cortical plate for a short period early in gestation ( 35-40 days ) , but mainly confined to the ventricular zones later and barely detectable by 80 days gestation .
