Changes in the electrophoretic mobility of cells from chick blastoderms during early development.
A change in cell surface charge density during early avian development is shown with a free-flow electrophoresis apparatus. The blastoderms of freshly laid eggs consist of two electrophoretically distinct cell populations. After the onset of gastrulation a third cell population with an intermediate electrophoretic mobility appears. With increasing time of incubation there is a shift in the proportion of these populations and an increase in the mobility of the fastest fraction.
