Apoptosis in Mammalian Embryos
2002The preimplantation development of eutherian mammals is remarkably similar, spanning cleavage of the fertilized ovum; compaction and morula formation; and finally cavitation, with the formation of a blastocyst. Blastocyst formation marks the differentiation of the epithelial trophectoderm (TE), which is specialized for implantation, and the ...

Cryobiology: Preservation of Mammalian Embryos
1986The preservation of mammalian embryos has become a routine procedure. Thousands of live offspring have been produced from frozen-thawed embryos transferred into recipient foster mothers. Species whose embryos have been successfully preserved include mouse, rat, rabbit, sheep, goat, cattle, horse, antelope, baboon, and human.

Cryopreservation of Mammalian Embryos
1988Early investigations of the effects of cooling and rewarming cells employed both spermatozoa and ova as experimental material. Spermatozoa were selected because of the ease of collection, inherent motility, and small size. Oocytes were employed mainly for their large size which allowed direct morphological observations.

Calcium and neurulation in mammalian embryos
Development, 1985ABSTRACT The role of calcium in neurulation in rat embryos has been studied. Rat embryos at 10-4 days of gestation, when the cephalic neural folds have elevated but not fused, have been cultured in various media, and the effects of these media on the morphology of the cephalic neural folds have been observed by scanning and transmission ...

Erythropoiesis in the mammalian embryo
Experimental HematologyRed blood cells (RBCs) comprise a critical component of the cardiovascular network, which constitutes the first functional organ system of the developing mammalian embryo. Examination of circulating blood cells in mammalian embryos revealed two distinct types of erythroid cells: large, nucleated "primitive" erythroblasts followed by smaller, enucleated

Encapsulation of Mammalian Embryos
1999Encapsulation of mammalian preimplantation embryos has its origins in the work of Willadsen in the late 1970s and in the need to develop an artificial zona pellucida for denuded sheep, horse, and cattle embryos used in the production of monozygotic twins for the livestock industry.

The Regulative Nature of Mammalian Embryos
2018The striking developmental plasticity of early mammalian embryos has been known since the classical experiments performed in the 1950s and 1960s. There are many lines of evidence that the mammalian embryo is able to continue normal development even when exposed to severe experimental manipulations of the number and position of cells within the embryo ...

Symmetry Breaking in the Mammalian Embryo
Annual Review of Cell and Developmental Biology, 2018We present an overview of symmetry breaking in early mammalian development as a continuous process from compaction to specification of the body axes. While earlier studies have focused on individual symmetry-breaking events, recent advances enable us to explore progressive symmetry breaking during early mammalian development.

Redox Control in Mammalian Embryo Development
Antioxidants & Redox Signaling, 2010The development of an embryo constitutes a complex choreography of regulatory events that underlies precise temporal and spatial control. Throughout this process the embryo encounters ever changing environments, which challenge its metabolism. Oxygen is required for embryogenesis but it also poses a potential hazard via formation of reactive oxygen and

Pioneering Mammalian Embryo Culture
1987In the fast pace and competitiveness of modern science, there is less and less time to teach students the background on how the currently used scientific methods and ideas came about. This fact is unfprtunate, for it is salutary to realize that many so-called discoveries and inventions are not new and that the old literature is replete with ideas.
