The phrase "av star" is not correct in English and does not convey a clear meaning.
It appears to be a misspelling or a mix of languages, and without context, it cannot be used appropriately in written English.
Example: "I am not sure what you mean by 'av star'."
Alternatives: "of star" or "a star.".
By investigating gene expression in the AV axis of an indirectly developing sea star, Yankura et al. [ 2] provide further evidence for the modularity of GRNs and for their evolvability and differential deployment in related animals with different developmental modes.
Taken together, the spatial expression of these regulatory genes demonstrates that the ectoderm of the sea star blastula is patterned along the AV axis in at least five nested concentric domains (summarized in Figure 2K).
One of the best, Aguila y Sol (Av Moliere 42, 0052 55 5281 8354), would probably have a Michelin star if it were in Europe.
Shooting Stars (1928, directed by Asquith along with AV Bramble) is a takedown of the film world as cheap and unoriginal, with overprivileged stars whose misbehaviour makes a mockery of their fans' devotion.
Sea star late blastulae have a morphologically distinct animal-vegetal (AV) axis that is first readily observed when elongation of cells at the vegetal pole results in a noticeable thickening of epithelium termed the vegetal plate [ 18].
It is divided into a right canal with a tricuspid AV valve (circle) separating the right atrium and the right ventricle and a left canal with a bicuspid (mitral) AV valve (star) separating the left atrium and the left ventricle.
Av de José Fernández López, +34 (0) 924 304512 More beautifully simple Spanish cooking, but the real star of the show here is the wine list – you'll find more than 150 wines from all over the country.
Transcripts of sea star regulatory genes are localized throughout the animal ectoderm in overlapping concentric domains along the AV axis.
