pubmed:abstractText |
SEM reveals that the subgerminal yolk surface of the chick and quail embryo during stages X to XIV possesses microvilli and small pits. Threadlike extensions and globular structures are found on the subgerminal yolk surface mainly in the central area. The cellular nature of the subgerminal yolk was confirmed with TEM that showed the presence of a plasma membrane, mitochondria, micro-invaginations and microfilaments. The ventral cells of the germ wall are yolky and can be attached to the subgerminal yolk surface with filopodial extensions during stages X to XII. From stage XIII, the shape of these cells is usually more flattened and they protrude lamellae and filopodia.
