The subclavian arteries normally supply blood to embryonic tissues that give rise to the chest wall and hand.
13.
The extra-embryonic tissue of these developing mice also showed increased rates of apoptosis and a decrease in cell proliferation.
14.
The tetraploid cells can form the extra-embryonic tissue ( placenta etc . ), however a proper fetus will rarely develop.
15.
As it penetrates the lining, the embryonic tissue grows aggressively till it forms sheets of tissue beneath the uterine epithelium.
16.
A modification of the original grid method is widely used to study the growth and differentiation of adult and embryonic tissues.
17.
The embryo, meanwhile, proliferates and develops both into embryonic and extra-embryonic tissue, the latter forming the fetal membranes and the placenta.
18.
Reproductive sex organs for both male and female are derived from the same embryonic tissues and are considered homologous tissues or organs.
19.
It would inject the eggs with embryonic tissue from birds bred to maximize meat production, at the expense of egg laying ability.
20.
Newman's work in developmental biology includes a proposed mechanism for patterning of the vertebrate limb skeleton based on the self-organization of embryonic tissues.
