Embryonic Development of the Orbit
Klinische Monatsblätter für Augenheilkunde, 2022AbstractThe embryonic and fetal development of the orbit comprises a series of sequential events, starting with the fertilization of the ovum and extending until birth. Most of the publications dealing with orbital morphogenesis describe the sequential development of each germinal layer, the ectoderm with its neuroectoderm ...

Waves in Embryonic Development
Annual Review of Biophysics, 2022Embryonic development hinges on effective coordination of molecular events across space and time. Waves have recently emerged as constituting an ubiquitous mechanism that ensures rapid spreading of regulatory signals across embryos, as well as reliable control of their patterning, namely, for the emergence of body plan structures.

Signaling oscillations in embryonic development
2022Tight spatiotemporal control of cellular behavior and cell fate decisions is paramount to the formation of multicellular organisms during embryonic development. Intercellular communication via signaling pathways mediates this control. Interestingly, these signaling pathways are not static, but dynamic and change in activity over time.

Embryonic development of endothermy
Respiratory Physiology & Neurobiology, 2011During embryonic development of homeothermic animals like birds and mammals transition from ectothermy to endothermy occurs especially in precocial species of both taxa. Based on some evolutionary aspects of the development of endothermy the review focuses on the prenatal development of endothermy and of the thermoregulatory system using the precocial ...

Asbestos and embryonic development
Teratology, 1977AbstractChrysotile asbestos was administered to pregnant CD‐I mice in their drinking water and to Day 4 blastocysts during culture. Administration to pregnant mice did not affect embryo survival. In vitro administration of asbestos did not interfere with embryo implantation upon transfer of blastocysts to recipient females but did result in a decrease ...

Autotaxin in embryonic development
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2013Autotaxin (ATX) is a secreted lysophospholipase D that generates the multifunctional lipid mediator lysophosphatidic acid (LPA). LPA signals through six distinct G protein-coupled receptors, acting alone or in concert to activate multiple effector pathways.

Embryonic and post-embryonic development
1981The modern era of insect developmental study began almost a century ago with the outstanding descriptive work of Wheeler (1889, 1893) in the United States and Heymons (1895) in Germany. It is ironic that the developmental analysis of cockroaches, among the most studied insects, has advanced so little since.

Ammonoid Embryonic Development
1996A great number of new studies have been carried out on ammonoid embryonic development in the last two decades. We focus here on novel developments and interpretations in the description of the embryonic shell (including terminology, shape, size, ornamentation, microstructure, septa, siphuncle and muscle scars), the sequence of embryonic development ...

Early mammalian embryonic development
American Journal of Industrial Medicine, 1983This report examines the major events occurring during the first month of development in the human embryo. Developmental events are detailed, beginning with cleavage of the zygote and ending with the formation of the three primary germ layers. Certain aspects of early human development are compared with that in lower forms of vertebrates to emphasize ...

Publisher Summary Embryonic development has fascinated scientists and philosophers from ancient culture to the present day. This chapter explores embryonic development. In attempts to unravel the mysteries of embryonic development, a few specific animal species have been used repeatedly, most often for straightforward practical reasons such as whether
