Following fertilization the embryonic stage of development continues until the end of the 10th week (gestational age) (8th week fertilization age). The first two weeks from fertilization is also referred to as the germinal stage or preembryonic stage.[6] The zygote spends the next few days traveling down the fallopian tube dividing several times to form a ball of cells called a morula. Further cellular division is accompanied by the formation of a small cavity between the cells. This stage is called a blastocyst. Up to this point there is no growth in the overall size of the embryo, as it is confined within a glycoprotein shell, known as the zona pellucida. Instead, each division produces successively smaller cells. The blastocyst reaches the uterus at roughly the fifth day after fertilization. It is here that lysis of the zona pellucida occurs. This process is analogous to zona hatching, a term that refers to the emergence of the blastocyst from the zona pellucida, when incubated in vitro. This ...

The respiratory system does not carry out its physiological function (of gas exchange) until after birth. The respiratory tract, diaphragm and lungs do form early in embryonic development. The respiratory tract is divided anatomically into 2 main parts: 1. upper respiratory tract, consisting of the nose, nasal cavity and the pharynx; 2. lower respiratory tract consisting of the larynx, trachea, bronchi and the lungs. In the head/neck region, the pharynx forms a major arched cavity within the phrayngeal arches. The lungs go through 4 distinct histological phases of development and in late fetal development thyroid hormone, respiratory motions and amniotic fliud are thought to have a role in lung maturation. Development of this system is not completed until the last weeks of Fetal development, just before birth. Therefore premature babies have difficulties associated with insufficient surfactant (end month 6 alveolar cells type 2 appear and begin to secrete surfactant). ...

In the article, Lab-Grown Mouse Embryos Form Limbs and Organs scientists had managed to develop a method that would allow them to grow a mouse embryo outside its mothers uterus. Traditionally when studying the embryonic development of a species; which had allowed scientists to understand how a single cell would develop into a body with specific cell types. To see how fetal development occurs and what important features are present during different stages surgical images were taken from cutting into the womb of the mouse. This time however scientists were able to artificially create a womb which allowed them to analyze the gestation of the embryo in real time without having to cut into the womb.. Having the right conditions to grow the embryo was important to maintain proper functionality and development. Conditions such as the right amount of pressure, oxygen, and nutrients were vital to sustain the embryos genetic material and even managed to get the embryo to develop functioning systems ...

The previous study of Abeliovich et al. (2000) and the results presented here are the only two studies performed to date describing the phenotypic consequences of a homozygous null mutation in the gene encoding α-synuclein. Both studies are consistent in the finding that normal mouse development, life span, and behavior are not affected by the lack of α-synuclein. Abeliovich et al. (2000) found that levels of DA in the striatum were reduced by ∼18% in the mutant compared with the wild-type animals. We found similar modest reductions in striatal levels of DA, but the wide variance in the measurements between different mice precluded drawing any conclusions about the significance of the reductions seen.. However, our study differs from that of Abeliovich et al. (2000) in two important ways. First, ultrastructural examination of synapses fromSnca−/− mice showed a reduction in the reserve-resting pool of synaptic vesicles in the hippocampus of mice lacking α-synuclein and in hippocampal ...

1. The general course of prenatal growth in the mouse, the guinea pig, and the chick can be expressed by straight line relations between the logarithms of the weight and age only when age is counted from the beginning of the embryo proper.. 2. This is interpreted as showing that the manner of growth before the beginning of the embryo proper is essentially different from that after this time.. 3. The velocity constants for the animals mentioned are similar; the major differences in their curves depend on the amount of tissue involved in the first organization of the embryo proper and in the length of prenatal life.. 4. Growth of different animals may be compared more accurately if, instead of either birth age or conception age, embryo age is used.. ...

N2 - A novel family of genes, characterized by the presence of a region of homology to the DNA-binding domain of the Brachyury (T) locus product, has recently been identified. The region of homology has been named the T-box, and the new mouse genes that contain the T-box domain have been named T-box 1-6 (Tbx1 through Tbx6). As the basis for further study of the function and evolution of these genes, we have examined the expression of 5 of these genes, Tbx1-Tbx5, across a wide range of embryonic stages from blastocyst through gastrulation and early organogenesis by in situ hybridization of wholemounts and tissue sections. Tbx3 is ...

TY - JOUR. T1 - Differential patterns of expression of Eps15 and Eps15R during mouse embryogenesis. AU - Offenhäuser, Nina. AU - Santolini, Elisa. AU - Simeone, Antonio. AU - Di Fiore, Pier Paolo. PY - 2000/7/1. Y1 - 2000/7/1. N2 - Eps15 and Eps15R are related tyrosine kinase substrates, which have been implicated in endocytosis and synaptic vesicle recycling. Through the protein:protein interaction abilities of their EH domains, they establish a complex network of interactions with several proteins, including Numb, a protein necessary for neuronal cell fate specification. We analyzed the expression of Eps15 and Eps15R during murine development, at the time of active neurogenesis. The most striking difference was at the level of subcellular localization, with Eps15 present in the cytosol and on the plasma membrane, while Eps15R exhibited mainly a nuclear localization. Interesting topographical differences also emerged. In the 12.5 days post coitum neuroepithelium, Eps15 was expressed in the ...
