TitlePaper, 'On the formation of the mesoblast, and the persistence of the blastopore in the lamprey' by Arthur E [Everett] Shipley
Date1885
DescriptionShipley writes: 'At the close of segmentation the egg of the lamprey (Petromyzon planeri) forms a blastosphere. Owing to the way in which the yolk is distributed, the segmentation cavity is rather eccentrically placed. It is roofed in by several rows of small cells, while its floor is composed of a few very large cells much crowded with food yolk.'
