They also found that
embryonic growth appears to be more sensitive to temperature at earlier stages of development and to moisture at later stages.
How do you visualise the extremely small forces connected to processes in our body, such
as embryonic growth and development?
Lee and McPherron discovered the gene about five years ago while examining genes known to
regulate embryonic growth and development.
In that sense, while it does to some degree
recapitulate embryonic growth, it does not match the process as faithfully as the optic cup recently reported by another Japanese researcher.
The next steps in cloning would be to 1) insert a donor nucleus of a new bird into the enucleated egg cell, 2)
stimulate embryonic growth, and 3) implant the embryo into a mother bird or egg.
Birds have benefited from millions of years of evolution to make the perfect eggshell, a thin, protective biomineralized chamber
for embryonic growth that contains all the nutrients required for the growth of a baby chick.
During embryonic growth, a gene that is similar in both flies and mice (and, by implication, humans) triggers the brain to divide into front, middle, and rear segments.
«If
the embryonic growth rate extends to hatchlings and juveniles, these [dinosaurs] grew very, very fast,» says Reisz.
Tracing the pedigree of nerve cells in
the embryonic growth of dwarf and giant leeches yields preliminary clues to the functioning of the adult nervous system
Vitamin A is an essential nutrient for a baby's
embryonic growth, and it also helps with tissue repair after labor and delivery.
