title: Ethylnitrosourea treatment increases lectin binding to mouse germ cells.
abstract: Germ cell toxicity was assessed by investigating the binding of FITC-labeled lectins to mouse testis cells before and 18 days after treatment with ethylnitrosourea (ENU). Flow cytometry of testis cells dual-labeled with FITC-lectin plus the DNA stain, propidium iodide, allowed analysis of haploid (1C), diploid (2C), and dividing (4C) cell populations. Soybean agglutinin, wheat germ agglutinin, concanavalin A and Limax flavus agglutinin bound to normal mouse testis cells containing 1C, 2C or 4C DNA. Asparagus pea lectin and Bandeireae simplicifolia I isolectin B4 did not. ENU treatment reduced the number of testis cells and increased lectin binding, particularly of those lectins which bound to untreated cells.
