title: Studies on intercellular adhesion. III. Adhesion of cells to isotypic or heterotypic collecting particles and monolayers.
abstract: Adhesion between cells of different tissues from chick embryos was studied by the modified collecting particle (Pessac et al., '77a) and stationary monolayer assays. These assays measure the number of 3H labeled cells that adhere to the surface of cell aggregates and tissue fragments or on top of cell monolayers. The numbers of cells from a given suspension that adhere to identical or different cells can be compared. Intercellular adhesion may be considered as tissue specific if, in identical conditions, more cells adhere to identical cells than to cells from different tissues. Neural retina, cerebrum, optic tectum, liver and kidney cells from 9-day-old chick embryos showed no tissue specificity of adhesion, while heart cells adhered preferentially to collecting heart fragments.
