Now,
with more ways to monitor gene activity during
development — and fully sequenced genomes of various snakes and other reptiles for comparison — Cohn and graduate student Francisca Leal have tracked the genetic activity

Embryonic development in mammals begins
with the division of the fertilized egg, which is then followed by several further rounds of division to form the blastocyst, a sphere of cells made up of two layers of cells surrounding a fluid - filled cavity.
However, malformation of skeletal bones during embryogenesis also occurs
in FOP patients and illustrates that the underlying genetic mutation occurs
in a gene
with functional importance
in regulating chondro - osseous differentiation during
embryonic skeletal
development as well as
in adult musculoskeletal tissues.
Although we agree that greater investments are needed
in the clinical
development of these therapies, we disagree
with the authors» suggestion that, relative to
embryonic stem cells, adult stem cells provide a superior vehicle for cell - based therapies because they lack tumorigenic activity, can be prepared by methods approved by the Food and Drug Administration (FDA), and have been free of ethical controversy.
CARS microscopy also confirmed the gradual increase of the size of lipid containing structures during oogenesis (Figs. 5A and 5B), the sudden re-localization of these structures to the periphery of the dividing nucleus
in the first
embryonic division (Fig. 5E), and the propagation of this phenotype, although
with gradually diminishing appearance, throughout
embryonic development (Figs. 5F and 5H).
In the new research, Pollen and co-first author Tomasz Nowakowski, PhD, also a postdoctoral researcher in the Kriegstein lab, partnered with Fluidigm Corp. to develop a microfluidic approach to map out the transcriptional profile — the set of genes that are actively producing RNA — of cells collected from the VZ and SVZ during embryonic developmen

Correspondingly, endothelial - specific deletion of Tie2 using Ve - cad - Cre driver mice, pursued
in validating the Tie2fl / fl mice used
in this study, essentially phenocopied the global Tie2 KO phenotype
with embryonic lethality around E10.5 (Supplementary Fig. 13), confirming the key role of endothelial Tie2 during
embryonic development.
Because NF - kB is also involved
in embryonic development, Verma and his team got together
with Juan Carlos Belmonte «s laboratory at Salk and turned to zebra fish to determine what would happen if IKK1 was deleted.
Eight HARs showed differences
in their enhancer activity when the human mutations were present.4 These differences modify how genes were expressed
in the developing limb (HAR2, 2xHAR114), eye (HAR25), and central nervous system (2xHAR142, 2xHAR238, 2xHAR164, 2xHAR170, ANC516 / HARE5).4, 10 Because relatively few time points have been examined, it is likely that an even higher percentage of the tested HARs are active enhancers at some point during
embryonic development or
in adult tissues, possibly
with human - chimp differences.
In view of the different timing of meiotic initiation in female and male mammals, we determined the developmental expression profile of mouse Boule during both male and female embryonic gonadal development (embryonic day 10.5, E12.5, E16.5 and E17.5) in comparison with adult gonad
