Early embryonic vascular development
Cardiovascular Research, 1996Abstract Establishment of a functional vascular system is imperative for normal embryonic growth and development. Building on the excellent descriptive studies of endothelial cell position and behavior, it is now possible to begin to define the mechanisms directing endothelial cell differentiation, commitment, migration and organization ...

Gravity and Embryonic Development
1976The relationship between the developing embryo (both plant and animal) and a gravitational field has long been contemplated. The difficulty in designing critical experiments on the surface of the earth because of its background of 1 g, has been an obstacle to a resolution of the problem.

Hypoglycemia and embryonic heart development
Frontiers in Bioscience, 2002Abnormal embryonic development is a complication of the diabetic pregnancy, and heart defects are among the most common and detrimental congenital malformations of the diabetic embryopathy. Hypoglycemia is a common side effect of diabetes therapy and is a potential teratogen. An association between hypoglycemia and congenital defects has been difficult

Embryonic Development and Induction
Nature, 1939AT last we have the pleasure of welcoming the largest work so far written by one who is perhaps the greatest living master of experimental morphology. It has received admirable treatment by the Yale University Press; the clear printing aids the reader's eye, and the matt paper does justice to every nerve-cell in the numerous illustrations.

Physiology of Embryonic Development
2013Human embryo development is a complex process. The life of an embryo begins when a male’s spermatozoa makes contact with a woman’s egg. A zygote cell, the very first representation of the fetus, is the result of this fertilization process. Contained within this one cell is the DNA of both the male and female, as well as the blueprint from which the ...

Conception control and embryonic development
American Journal of Obstetrics and Gynecology, 1970Abstract This paper presents the results of a study of normal and abnormal fetuses delivered by women who had recently been employing a particular method of contraception. The incidence of abnormal development and the types of abnormality are presented and a comparison is made with abortions where no contraceptive technique has been used.

Collagen and Embryonic Development
1981The possible importance of the extracellular matrix (ECM) to the development of the vertebrate embryo has been recognized since the turn of the century, but it was not until the fine structure of the molecule was fully appreciated that the first serious thought was given to a role of collagen per se in morphogenesis (see Gross, 1956).

Analysis of Embryonic Development
1988A comprehensive review of mammalian embryo culture in vitro is presented in Chapter 18. Additionally, a discussion of embryo quality as it relates to embryo freeze-thaw survival can be found in Chapter 16. This chapter, along with Chapter 8, is designed to supplement Chapter 10.

Embryonic and Fetal Development
1974Many clinical studies have established the potential value of certain prostaglandins for the termination of pregnancy at all stages of gestation and for the induction of labor (Anderson and Speroff, 1973). Undoubtedly, the surge of interest in the clinical application of prostaglandins as therapeutic and antifertility agents will continue.
