[The marker histochemical detection of glucose-6-phosphate residues in the human placenta]. 1992

A L Glazyrin, and S I Kolesnikov

Glucose-6-phosphate residues were revealed by fine structural analysis using glucose-6-phosphate dehydrogenase-gold conjugate. In human mature placenta specific staining was detected over the stroma of placental villi. Colloidal gold particles were found over the collagen fibrils and reticular lamina of basal membrane. Syncytiotrophoblast cells, fibroblasts, endothelial cells of fetal capillaries avoided labelling. Nucleated blood cells and thrombocytes inside the lumen of fetal capillaries demonstrated intense staining. The present investigation demonstrates histochemically the process of extracellular glycosylation. Glycated collagen fibrils formed channels inside the stroma of placental villi.

UI	MeSH Term	Description	Entries
D010920	Placenta	A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES).	Placentoma, Normal,Placentome,Placentas,Placentomes
