Observation of Cell Division in a Fertilized Egg of a Zebrafish by Using a Multimodal Nonlinear Optical Microscope

Abstract

© 2019, The Korean Physical Society.We have developed a high-speed and high-resolution multimodal nonlinear optical microscope, which can acquire in vivo label and label-free 3D images. Using this microscope, we could successfully observe dynamic images of the zebrafish heartbeat with 33-millisecond intervals without staining process, indicating 1.68 beats per second. In addition, we show that the label-free, high-speed, real-time images can be obtained during somatic cell divisions in the zebrafish’s embryo
