Embryogenesis

Post by tnnn » Mon May 23, 2011 1:18 pm

I was working through a bunch of questions. But one of them I could not seem to get my mind across.

Of the main processes in embryogenesis, which begins first?
a)Programmed Cell Death
b)Cell differentiation.
c)Cell proliferation.
d)Cell migration.

I don't think it is programmed cell death, nor cell migration. I am thinking between differentiation and proliferation. I know that zygotes undergo cleavage, and that increases the amount of cells, but does not effect the size overall. So perhaps differentiation?

I am not very sure. I anxiously await for your responses, it's getting on my nerves. :D Thanks.

I think that proliferation is the division, not necessarily related to growth in volume, isn't it? The differentiation will be one of last.

Cis or trans? That's what matters.

Although, any further replies explaining why its proliferation first would be appreciated. Is it because cells need to proliferate before they start to differentiate? (Just by logic)
