abstract：:We have investigated the origin of rapidly adhering (RA) cells in three cases of neural tube defects (two anencephali, one encephalocele). We were able to demonstrate the presence of glial fibrillary acidic (GFA) protein in variable percentages (4--80%) of RA cells cultured for 4--6 days by use of indirect immunofluor...
