Thirteen carp tissues (heart, liver, kidney, hindbrain, spleen, foregut, hindgut, muscle, gill, eye, scale, fin and gonad) were collected from six 2-year-old healthy adults (three females and three males), and five critical periods of embryonic development (blastula, gastrula, neurula, tail-bud and hatching) were obtained from embryos.
Nestin is a widely used NSC marker, and its expression initiates from the formation of neurula. With the differentiation and maturity of the neurons, the expression of nestin is gradually diminished and lost.
A recent study showed that expression of notochord-specific genes with multiple and single functional Brachyury binding sites begins around the early gastrula and neural plate stages, respectively, and expression of indirect targets of Brachyury begins around the early neurula stage.
The early neurula is finished with formation of the expressed nervous plate and a cavity of a primary gut.
In the current study, messenger RNA (mRNA) will be obtained from cardiac tissue of embryos that have been treated with 100nm of ATRA in the neurula stage of development.
Twenty-four hours after mating, embryos at the early-cleavage, blastula, gastrula, neurula, and tadpole stages were collected, preserved in Bouin's fixative, sputter coated with a mixture of platinum and gold, and observed using a scanning electron microscope (S-2460N, Hitachi).
To study the ontogenetic expression profiles, fertilized embryos and larvae from different developmental stages (fertilized, 2-cell, multicellular, midgastrula, neurula, muscular contraction, pre-hatching, post-hatching, seven days post-hatch) were collected following natural spawning of the brood stock.
In my experiment, when the egg became flattened, two neural tubes occurred in the neurula, and then a twin embryo was produced.
Their cell division is finished by the neurula stage (Miyamoto and Crowther, 1985; Munro and Odell, 2002a; Jiang et al., 2005).
