Abstract

Immunocytochemical distribution of the fetal protein fetuin in the neocortex of developing rat brain and the presence of its mRNA, as detected by using reverse transcriptase-polymerase chain reaction analysis, was studied in fetuses at embryonic day 15 (E15) through E22, in neonates at postnatal day 0 (P0) through P20, and in adults. Quantitative estimates of fetuin in cerebrospinal fluid (CSF) and plasma were obtained over the same period. Exogenous (bovine) fetuin injected intraperitoneally into fetal and postnatal rats was used to study the uptake of fetuin into CSF and brain and its distribution compared with endogenous fetuin; bovine albumin was used as a control. Fetuin was identified ..
