These blastomere volume measurements were used in conjunction with visual inspection of the image data when making lineage assignments of dividing blastomeres, using the reasoning that the sum of volumes of daughter cells would be approximately equal to the volume of the mother cell.
You aren't sure whether to sigh at his vanity -- while Whitman's example isn't out of place in considerations of Dylan as a media-age bard, it's fatuous for the man himself to make the lineage so explicit -- or to admire how craftily he's embedded the constellation of allusions in the text that leads up to this payoff.
Miles Marshall Lewis commented that 1990s neo soul "owed its raison d'être to '70s soul superstars like Marvin Gaye and Stevie Wonder", adding that "in concert, Erykah Badu and D'Angelo regularly covered Chaka Khan, the Ohio Players, and Al Green, to make the lineage crystal clear".
The distributions of these two genera, with one endemic to the islands of Southeast Asia and the other restricted to the Laurasian mainland, make this lineage particularly interesting for addressing temporal and spatial patterns of diversification in Southeast Asia.
These will include, in addition to those mentioned, lineages of mobile acellular genetic elements such as viruses and plasmids, and lineages of symbiotic communities of interacting organisms, though the complexity of the processes that sustain the latter may make their lineage formation less central to the analysis.
In the liver, the opportunity to label cells in vivo makes lineage study feasible in the absence of any ex vivo manipulation of the cells that will be studied.
Embryonic stem cells (ESCs) are derived from mammalian embryos during the transition from totipotency, when individual blastomeres can make all lineages, to pluripotency, when they are competent to make only embryonic lineages.
This coexpression of pluripotency genes and trophoblast determinants is reminiscent of the stages of preimplantation development when blastomeres are competent to make all lineages.
However, the samples of north-eastern France and southern Germany show an intermediate genetic structure between this lineage and the south-western Alps lineage, making hybrid origin of these populations rather likely and thus expansion of the southern Alps lineage over the chains of the Alps.
