blastocoel การใช้

• The endoderm of the archenteron will fuse with the ectoderm of the blastocoel wall.
• The vegetal mass is composed of the blastocoel floor and primarily develops into endodermal tissue.
• Once in the blastocoel, the mesenchyme cells extend and contract long, thin processes called filopodia.
• The equatorial or marginal zone, which compose the walls of the blastocoel differentiate primarily into mesodermal tissue.
• The blastocoel fluid cavity contains amino acids, growth factors, and other necessary molecules for cellular differentiation.
• The filopodia thin fibers formed by the mesenchyme cells found in a late gastrula contract to drag the tip of the archenteron across the blastocoel.
• At this point, the filopodia appear to move randomly along the surface of the inner blastocoel, making and breaking filopodial connections to the blastocoel wall.
• At this point, the filopodia appear to move randomly along the surface of the inner blastocoel, making and breaking filopodial connections to the blastocoel wall.
• Their principal body cavity is the " hemocoel " or " haeomocoel " of an open circulatory system, often derived from the blastocoel.
• During the gastrula stage, once the blastopore has formed, the PMCs are localized within the prospective ventrolateral ( from front to side ) region of the blastocoel.
• Unlike nectonematiodeans, gordioideans lack lateral rows of setae, have a single, ventral epidermal cord and their blastocoels are filled with mesenchyme in young animals but become spacious in older individuals.
• Lastly, these cells will modify their mode of motility and presumably gain affinity for the basal lamina which composes the lining of the blastocoel, the future migration substrate of the PMCs,.
• In the blastula, these cadherin mediated cell interactions are essential to development of epithelium which are most important to paracellular transport, maintenance of cell polarity and the creation of a permeability seal to regulate blastocoel formation.
• The outer cells, called the trophoblast cells, pump sodium in from the outside, which automatically brings water in with it to the basal ( inner ) surface to form a blastocoel cavity in a process called compaction.
