Top left: A chick dosal root ganglion growth cone visualized with YFP‐fascin (see Ohashi). Center: Clathrin‐coated pits visualized by EGFP‐clathrin in the growth cone (see Tojima & Kamiguchi). Right: The sequence of invagination of the Drosophila tracheal placode (from left to right). Green: Crumbs (apical marker), Magenta: tracheal cells (see Kondo & Hayashi). Middle left: Human dermal fibroblast cells that incorporate lactic acid bacteria (Magenta) gain multipotency (See Ohta). Right: Maximum‐intensity projection of lightsheet Z stacks from the 34 hpf transgenic zebrafish embryos. Red/orange: endoderm, Cyan: cardiomyocyte, Violet/white: blood vessel, Grey: yolk. Cardiac precursor cells (CPCs) migrate to the midline beneath the endoderm to form heart. (See Fukuhara et al.). Bottom left: Regenerated tail of the Xenopus tadpole at 7 days post amputation, tail stuructures being emphasized. Tadpoles can regenerate all the component of the tail; the spinal cord, notochord, muscles, vessels and skin (See Hayashi et al.). Right: An ascidian tailbud stage embryo with the germline of the B7.6 blastomere descendants labeled by DiI (see Kumano)
