The coelom (body cavity) forms from a split in the embryonic mesoderm (middle tissue).
Most of the potential colonies were picked up and split onto mouse embryonic fibroblast (MEF) feeder cells to derive hiPSC lines.
Together, our findings of consistent spawning times, split-spawning, rapid embryonic development, and remarkable robustness of larvae and settlers now enable expanded research on the early life history and settlement ecology of D. cylindrus.
His work is split 50/50 between human embryonic cells and those taken from adult animals.
Three microliters of embryonic DNA was split between wild-type and mutant allele genotyping reactions (45 cycles of PCR), followed by agarose gel electrophoresis.
The anteriormost structure of the germband, homologous to the appendage-bearing domain of the lower-stem taxa's anterior appendage, retreats posteriorly, thus splitting the anterior of the embryonic axis.
To assess the influence of moisture on anomalies during the embryonic development, every clutch was split into two boxes with different substrate water potentials: −150 kPa (wet) and −600 kPa (dry) [46], [47].
The hairy/enhancer-of-split (HES) group of transcription factors controls embryonic development, often by acting downstream of the Notch signaling pathway; however, little is known about postembryonic roles of these proteins.
Senator Lincoln Chafee, Republican of Rhode Island, and Representative Deborah Pryce, Republican of Ohio, boast that they split with Mr. Bush and voted for research using embryonic stem cells.
First, the mouse is evolutionarily very close to humans (the split occurred 70 million years ago) and its embryonic development recapitulates many aspects of human development in terms of body structure formation and gene activation.
