Embryonic to adult conversion of neural cell adhesion molecules in normal and staggerer mice.

The neural cell adhesion molecule (N-CAM) has an unusually high amount of sialic acid (28-35 g/100 g of polypeptide) and shows microheterogeneity in electrophoretic gels in its embryonic or E form. During development, the molecule undergoes conversion to several adult or A forms, which resemble the E form but which on the average have only 10% sialic acid and do not appear to be microheterogene...

Differences in the carbohydrate structures of neural cell-adhesion molecules from adult and embryonic chicken brains.

Adult chicken brain membranes were found to contain an antigen that is immunologically related to the neural cell adhesion molecule (N-CAM) previously isolated from embryonic tissue (1). Adult N-CAM was purified from Nonidet P-40 extracts of brain membranes by affinity chromatography using a monoclonal antibody to embryonic N-CAM with a yield (9 mg/250 g of tissue) comparable to that from embry...

Expression of cell-adhesion molecules in embryonic induction. II. Morphogenesis of adult feathers

The developmental appearance of cell-adhesion molecules (CAMs) was mapped during the morphogenesis of the adult chicken feather. Neural CAM (N-CAM), liver CAM (L-CAM), and neuron-glia CAM (Ng-CAM), as well as substrate molecules (laminin and fibronectin), were compared in newborn chicken skin by immunohistochemical means. N-CAM was found to be enriched in the dermal papilla, which was closely a...

Neural cell adhesion molecules during embryonic induction and development of the kidney.

The neural cell adhesion molecules (N-CAM) are a family of related glycoproteins with Mr of 180, 140 and 120 x 10(3) (180K etc.). In the embryo, they are often highly sialylated and migrate as a diffuse band of 170-250K. N-CAM are found in non-neural tissues and we have now studied the expression of N-CAM in the developing mouse kidney. During kidney development, a unique conversion of a mesenc...

Neural GPI-anchored cell adhesion molecules.

When first identified, neural cell adhesion molecules (neural CAMs) were thought to act simply by providing cell surfaces with differential adhesion properties. In the decades following the identification of the first neural CAMs, it has been realized that these proteins are actually involved in very complex processes such as axon guidance, neuronal migration, neurite outgrowth and fasciculatio...
