About

Nothobranchius furzeri time lapse. A Nothobranchius furzeri embryo has been followed through bright-field time lapse imaging from the one-cell stage to the dispersed phase. Cells divide at the animal pole (top part, above the yolk) and then migrate over the yolk surface (sec 21) during epiboly. Macroblastomers (big cells) can be spotted moving randomly and following the epiboly migration layer. When epiboly is complete (sec 54) macroblastomers continue moving randomly during the dispersed phase, that will last for several days.
