Embryotoxic effects of heterologous antisera against rat Reichert's membrane. 1977

C C Leung

Parietal yolk-sacs of rat embryos at the fifteenth day of gestation were obtained by microdissection. A Reichert's membrane (RM) preparation was isolated by treating the parietal yolk-sacs with the chelating agent tetrasodium salt of ethylenediaminetetraacetic acid (EDTA) combined with mechanical shaking. Less than 1% of the membrane preparation was DNA and phosphorus contaminants. The membrane purity was also evaluated by electrom microscopic examination. Rabbit Ig G directed against the RM preparation when injected ip into ninth day pregnant rats produced malformations, fetal growth retardation and resorption. Fluorescent-labeled antibody localization studies demonstrated that the teratogenic antibodies localized in RM. It is postulated that RM antibodies induce teratogenesis by interfering with the function of RM.

D005327	Fetal Resorption	The disintegration and assimilation of the dead FETUS in the UTERUS at any stage after the completion of organogenesis which, in humans, is after the 9th week of GESTATION. It does not include embryo resorption (see EMBRYO LOSS).	Fetal Resorptions,Resorption, Fetal,Resorptions, Fetal
D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
