In contrast with previous results, they observed the expressions of both miRNAs and piRNAs are firstly increased and then decreased, with a peak expression at sphere stage for miRNAs and shield stage for piRNAs, respectively [ 19].
A tin trough was later added to reflect the lights onto the stage and to shield them from the view of the audience.
As shown in Figure 1a, its maternal transcript existed from one-cell stage and held to shield stage until the zygote expression was initiated from this stage.
As shown in Figure 1b, the maternal zNoxa protein also existed from one-cell stage and held to shield stage until the zygote zNoxa protein was expressed from 75% epiboly stage.
A common trend in the expression-levels of the selected genes was observed upon ERK2 depletion, as most genes showed stabilization in their expression levels between 30% epiboly and shield stage, and even recovery between 6 to 8 hpf.
Geochemical evidence from Lōihi lavas indicates that Lōihi is in transition between the preshield and shield volcano stage, providing valuable clues to the early development of Hawaiian volcanoes.
Chp transcripts accumulated significantly at 50% epiboly (shield stage) and were maintained up to 48 hpf.
At the shield stage and the tail bud stage the staining focuses at the area where the somites will develop.
Total RNA was extracted from ~60 zebrafish embryos at shield stage, and from the whole body of a 4-month adult, using the Chomczynski and Sacchi method [ 19].
Expression pattern analysis indicates that zNoxa transcript is of maternal origin, which displays a uniform distribution in early embryonic development until shield stage, and the zygote zNoxa transcription is initiated from this stage and mainly localized in YSL of the embryos.
