Rapidly adhering cells in two cases of anencephaly.

We report the successful use of a new method described by Gosden and Brock (1977) in two cases of anencephaly; according to this method 'rapidly adhering cells' are identified as neural cells of a specific morphology. Although the original method described adherence of cells during the first 20 h, we were able to identify a considerable number of such cells after a delay of three days due to mailing of the amniotic fluid.
