Abstract: | A rapid and sensitive assay for measuring myoblast fusion in suspension cultures of embryonic chick pectoral myoblasts is described. Fusion-competent cells are generated by growth in suspension using a low calcium medium. Fusion-promoting levels of calcium are added, and the suspensions incubated for 1–6 h. The cells are then trypsinized to disperse cellular aggregates and sized in a Coulter particle counter. This assay minimizes many of the artifacts inherent in measurements of fusion in monolayer cultures, and is designed for the rapid screening of agents for their effects on fusion. |
