Mammalianembryogenesis is the process of cell division and cellular differentiation during early prenatal development which leads to the development of a mammal ian embryo . Difference from human embryogenesis Main Human embryogenesis Most mammal s develop similarly to Homo sapiens during the earliest stages of development, the embryo is largely indistinguishable from another mammal. However, there are phenomena found in human beings not found in all other mammals, as well as phenomena occurring in other mammals, but not in humans. Humans Mammals do not necessarily have the same human chorionic gonadotropin released from their embryo. Non human mammals The anatomy of the area surrounding an embryo or fetus, however, is different in litter bearing animals compared to humans each unborn animal is surrounded by placental tissue and is lodged along one of two long uterine horns rather than in the center of the pear shaped uterus found in a human female.

Embryogenesis starts with the fertilization of the ovum or egg by sperm . The fertilized ovum is referred to as a zygote . The zygote undergoes rapid mitosis mitotic cell division division s with no significant growth a process known as cleavage embryo cleavage and cellular differentiation , leading to development of an embryo. Although embryogenesis occurs in both animal and plant embryogenesis plant development , this article addresses the common features among different animals, with some emphasis on the embryonic development of vertebrates and Mammalianembryogenesis mammals .

It is also covered with different protective envelopes, with different layers.

Refimprove date July 2008 Plant embryogenesis is the process that produces a plant embryo from a fertilised ovule by asymmetric cell division and the differentiation of undifferentiated cells into tissues and organs. It occurs during seed development, when the single celled zygote undergoes a programmed pattern of cell division resulting in a mature embryo. ref Su rez, Mar a F., and Peter V. Bozhkov. 2008. Plant embryogenesis. Totowa, NJ Humana Press. p 3. ref A similar process continues during the plant s life within the meristems of the Plant stem stems and root s. Seeds Embryogenesis occurs naturally as a result of sexual fertilization and the formation of the Zygote zygotic embryo s. The embryo along with other cells from the motherplant develops into the seed or the next generation, which, after germination , grows into a new plant. Embryogenesis may be divided up into two phases, the first involves morphogenesis morphogenetic events which form the basic cellular pattern for the development of the shoot root body and the primary tissue layers it also programs the regions of meristem meristematic tissue formation. The second phase, or postembryonic development, involves the maturation of cells, which involves cell growth and the storage of macromolecules such as oils, starches and proteins required as a food and energy supply during germination and seedling growth. Embryogenesis involves cell growth and division, cell differentiation and apoptosis programmed cellular death . ref Current topics in developmental biology v. 67. 2005. S.l.

Unreferenced date October 2006 File Oocyte Poles.jpg thumb An oocyte with poles depicted In developmental biology , a blastula embryo is divided into two hemispheres the animal pole and the vegetal pole . The animal pole consists of small cells that divide rapidly, in contrast with the vegetal pole below it. The animal pole draws its name from its liveliness relative to the slowly developing vegetal pole. In some cases, the animal pole is thought to differentiate into the later embryo itself, forming the three primary germ layers and participating in gastrulation . The vegetal pole contains large yolky cells that divide very slowly, in contrast with the animal pole above it. The vegetal pole draws its name from its inactivity relative to the lively animal pole. In some cases, the vegetal pole is thought to differentiate into the extraembryonic membranes that protect and nourish the developing embryo, such as the placenta in mammals and the chorion in birds. In frog, Xenopus laevis pigment pattern provides the oocyte with features of radially symmetrical body with a distinct polarity. The animal hemisphere is dark brown, and the vegetal hemisphere is only weakly pigmented. The axis of symmetry passes through on one side the animal pole, and on the other side the vegetal pole. The two hemispheres are separated by an unpigmented equatorial belt. Polarity has a major influence on the mergence of the embryonic structures. In fact, the axis polarity serves as one coordinate of geometrical system in which early embryogenesis is organised. ref P. Hausen, M.

The small size, short generation time, and large brood size make it ideal for genetic studies. Transparent embryos facilitate developmental studies. Drosophila melanogaster was introduced into the field of genetic experiments by Thomas Hunt Morgan in 1909. Life cycle Drosophila display a holometabolous method of development, meaning that they have three distinct stages of their post embryonic life cycle, each with radically different body plans larva, pupa and finally, adult. The machinery necessary for the function and smooth transition between these three phases develops during embryogenesis. During embryogenesis , the larval stage fly will develop and hatch at a stage of its life known as the first larval instar. Cells that will produce adult structures are put aside in imaginal disc s. During the pupal stage, the larval body breaks down as the imaginal disks grow and produce the adult body. This process is called complete metamorphosis biology metamorphosis . The mother fly produces oocyte s that already have anterior posterior and dorsal ventral axes defined by maternal activities. Embryogenesis in Drosophila is unique among model organisms in that cleavage occurs in a syncytium strictly a coenocyte . About 5,000 nuclei accumulate in the unseparated cytoplasm of the oocyte before they migrate to the surface and are encompassed by plasma membranes to form cells surrounding the yolk ... zygote zygotically produced mRNA.

During the rut also known as the rutting period, and in sheep sometimes as Glossary of sheep husbandry tupping , males often rub their antler s or horn anatomy horn s on trees or shrubs, fight with each other, wallow in mud or dust, and herd estrus females together. The rut in many species is triggered by a shortening of the length of daylight hours each day. The timing of the rut for different species depends on the length of their gestation period length of pregnancy , usually occurring so the young are born in the spring, shortly after new green growth has appeared which provides food for the females, allowing them to provide milk for the young , and when the temperatures are warm enough that the young will not die of hypothermia . White tailed deer The rut for white tailed deer Odocoileus virginianus usually lasts from 1 3 months in the Northern Hemisphere and may occur most of the year in tropical zones. The rut is the time when white tailed deer, especially bucks, are more active and less cautious than usual. This makes them easier to hunt, as well as more susceptible to being hit by motor vehicles. ref http www.gameandfishmag.com hunting whitetail deer hunting gf aa106102a Understanding the Rut , Game and Fish ref Some people believe that the white tailed deer rut is also controlled by the lunar phase and that the rut peaks seven days after the second full moon the rutting moon after the autumnal equinox on 21 September.

It lies above the hypoblast . Mammals In mammalian embryogenesis , the columnar cells of the epiblast are adjacent to the trophoblast , while the cuboidal cells of the hypoblast are closer to the blastocoele . The epiblast, whilst referred to as the primary ectoderm, differentiates to form all three layers of the trilaminar germ disc in a process called gastrulation . Epiblast diversity Human epiblast is disc shaped as opposed to the mouse epiblast which is cup shaped.
