What the candidate has done here is told the big lie about embryonic stem cells. |
Other authors have proposed that such teratomas may originate from totipotential embryonic rests in the left genital ridge. |
They found two genes switched on in the amniotic epithelial cells that heretofore were believed to only be expressed in embryonic stem cells. |
Typically, altered gene dosage caused by karyotypic abnormalities results in embryonic lethality or birth defects. |
If you were to watch an embryonic starfish develop, you would see that it begins life bilaterally, but switches to radial symmetry as it matures. |
Early embryonic development in many plants is characterized by asymmetric cell division of the zygote, which specifies apical and basal regions. |
