Following the Sugar Right From the Start: Berkeley Researchers Image Glycans on Embryonic Cells Hours After Fertilization

Researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC), Berkeley, have successfully attached imaging probes to glycans – the sugar molecules that are abundant on the surfaces of living cells – in the embryos of zebrafish less than seven hours after fertilization. Glycans are key regulators of the processes that guide cell development, and zebrafish are a top vertebrate model organism of embryogenesis. This new technique enables scientists to study the physiological changes cells undergo during embryogenesis without invading and doing damage to the embryos. More>
