Zygote Question

Post by Condraz23 » Wed Dec 20, 2006 10:20 am

Why do animal zygotes always clump together while dividing?

Maybe clumping together is the only way in order for the animal zygotes to divide themselves.

I have checked wikipedia, not much info though...

Some kind of cell adhesion proteins, E-CAM.

i think morphogenesis in animal cells involve the cytoskeleton, and this process call convergent extension, where a sheet of dividing cells tend to become narrower and longer.

the other part involves glycoproteins in the extracellular matrix that help cells migrate along certain routs (e.g. fibronectin maybe?)

the CAMs are on the surfaces of cells, and they bind to each other. One example is cadherin, i think.

Some chemical messengers are found on surface of these cells those will let them be together.....
