From: Embryogenesis and early larval development in bocachico (Prochilodus magdalenae) in Colombia
A Prochilodus magdalenae, developmental blastula period from (A) 128C:128- cell; (B) 256C: 256-cell; (C) 512:512-cell; (D) > 1 K: High; to (E) 30% e.b.: 30% epiboly. B Prochilodus magdalenae, developmental blastula period. The cells are organized in more than 10 rows. A 10% epiboly stage is recognized, and a layer of elongated cells appears with slightly basophilic oval nuclei yolk syncytial layer (YSL) as part of the vitellus and support the animal pole, H&E 10X. Abbreviations: AP: animal pole; SC: syncytial cells; YG: yolk granules
