Summary
Erythroblasts from marrows of chicks infected with RNA-virus (strain Rerythroblastosis virus) were found to possess a small but consistent increase in the number of concanavalin A binding sites per cell compared to erythroblasts derived from the marrows of phenylhydrazine-treated birds. Both types of erythroblast possessed more surface glycoproteins per cell accessible to concanavalin A (Con A) than marrow and peripheral blood erythrocytes. Employment of concanavalin A conjugated to ferritin showed marked differences in the spatial arrangement of the Con A receptors between phenylhydrazine and virus-induced erythroblasts but little difference was observed in the surface density of the Con A sites between erythrocytes and erythroblasts, a result which agrees with the amount of bound labeled Con A when this data is expressed in terms of the cell surface.
The amount of labeled Con A bound to erythrocytes derived from the marrow was greater than that derived from the peripheral circulation, a result which is substantiated by the ferritin Con A studies which show an increase in the density of Con A sites on the marrow blood cells. Trypsinization increases the number of sites and the agglutininability of the marrow cells.
The increase in the susceptibility of the cells to agglutinate with concanavalin A paralleled the observed increase in the number of binding sites per cell.
