Fuentes, Ricardo; Fernández, Juan (WILEY-LISS, DIV JOHN WILEY & SONS INC, 2010-05-24)Patterns of cytoplasmic movements and organization of transport pathways were examined in live or fixed zygotes and early zebrafish embryos using a variety of techniques. The zygote blastodisc grows by accumulation of ...
