Embryonic Development: Putting on the finishing touches
Insect (Drosophila) and frog (Xenopus) development (and probably that of animals in general) passes through three rather different (although often overlapping) phases: ...

THE TERM Embryology, in its widest sense, is applied to the various changes which take place during the growth of an animal from the egg to the adult condition: it is, however, ...

An embryonic cell that can replicate indefinitely, transform into other types of cells, and serve as a continuous source of new cells.

Embryos and mouse strains
Wild-type embryos were from ICR outbred mice (Harlan-Sprague-Dawley, Indianapolis, USA). The TOPGAL mouse line was kindly provided by Elaine Fuchs [19].

embryo Term applied to the zygote after the beginning of mitosis that produces a multicellular structure.
embryo sac Alternate term applied to the angiosperm female gametophyte contained within a megaspore. PICTURE ...

Embryonic stem (ES) cells: Cell lines derived from early embryos that have the potential to differentiate into all types of somatic cells as well as to form germ line cells, and hence whole animals, when injected into early embryos.

Embryology is the study of the early development of organisms.

embryo The earliest of stage of development of a plant or animal. In humans, embryo is used up to the third month of pregnancy. Thereafter, once the basic body shape has formed, the term fetus is employed. PICTURE OF CHICK EMBRYO ...

Embryology: blastula, ectoderm, endoderm, fertilization, gestation period.

embryo [Gr. embryon]. The stage in a developing organism after cleavage has occurred and before hatching or birth.

embryo. The small plantlet within the seeds in almond, the embryo develops into the kernel.
endoparasite. A parasite that lives inside its host.

embryo forms when all the organs of the body have taken shape.
embryology the study of embryonic development.
endergonic reaction chemical reactions in which energy is obtained and trapped from the environment.

Embryonic stem cell ethical debate
A blastocyst is a stage of development of an embryo when it is around five days old and made up of about 100 cells.

embryology - study of embryogenesis, the development of animals and plants from fertilization to birth/hatching.

Embryonic development of the vertebrate brain reflects its evolution from three anterior bulges of the neural tube.

Embryo: A developing offspring during the period when most of its internal organs are forming. It is called fetus in the next stage of development.

Embryo and Seed Development
Embryogenesis, the formation of a multicellular embryo from a single-celled zygote, is one of the most dramatic and best-characterized aspects of plant development.

Another difficulty in comparing traits between species rests on the fact that homologous structures not present in the adult organism often do appear in some stage of embryonic development.

Embryonic stem (ES) cells
An embryonic cell that can replicate indefinitely, transform into other types of cells, and serve as a continuous source of new cells.

Embryonic germ layers begin to be committed toward distinct developmental fates
Cell migrations are a prominent feature of this developmental stage ...

Embryonic stem cells can be cultured in vitro; under certain conditions they can be induced to differentiate into various cell types.

Embryologists select which embryos will be placed into the uterus. Therefore they decide the fate of new individuals as they choose which ones will survive and which ones will die.

Embryonic stem cells have the other advantage that they are multipotent and can turn into many different types of tissue in culture and therefore it's possible to learn from studying embryonic stem cells how differentiation occurs.

embryo The early developmental stage that, through embryological development, ultimately becomes an adult individual.

Embryological development reveals a unity of plan. During development, all vertebrates have a notochord and paired pharyngeal pouches. In fishes and amphibian larvae, the pouches become gills.
