Homotypic Adhesion

An improved assay for measuring intercellular adhesive selectivity of embryonic chick liver cells is described. Three major improvements over earlier procedures are noted: (a) enhanced reproducibility of liver cell-liver cell aggregate adhesion (homotypic adhesion) was achieved; (b) 25-70% of the input cells adhered to the collecting aggregates during the course of routine experiments as compared to the 0.25% in earlier assays. This increase in cellular adhesion suggests that the observed cell pick-up is a characteristic of the majority of the dissociated liver cell population; (c) the rate of intercellular adhesion was increased 1,000-fold. The main feature of the assay is that it measures the tissue adhesive selectivities of the dissociated cell population. Studies were undertaken on three embryonic chick tissues (liver, neural retina, and mesencephalon) to determine the tissue selectivity of intercellular adhesion of these dissociated cell types. Some general properties of liver cell homotypic adhesion have been studied and are reported.

Nuclear DNA-dependent RNA polymerases were isolated from Ehrlich ascites carcinoma, TA3 ascites adenocarcinoma, and mouse liver and tested for inhibition by glycerol. The results confirm the finding of Smith and Duerksen ((1975) Biochem. Biophys. Res. Commun. 67, 916–923) that glycerol may inhibit nuclear RNA polymerase II, but because different grades of glycerol inhibited mouse liver RNA polymerase IIa to different extents, it is suggested that an inhibitory contaminant is present. RNA polymerases IIa and IIb from the two tumors and mouse liver were proportionately inhibited by A.C.S. reagent-grade glycerol at concentrations above 10%. RNA polymerase Ia from liver and the TA3 tumor was not inhibited by any concentration of glycerol tested (2–32.3%), but RNA polymerase Ia from Ehrlich carcinoma was inhibited by glycerol concentrations above 16%.
