Superovulation of female mice delays embryonic and fetal development [PDF]
Human Reproduction, 2001 Mouse and human embryos, cultured in vitro, undergo a delay in development compared with those grown in vivo. This delay can be caused by suboptimal culture conditions, but possible influences of ovarian stimulation cannot be excluded. The objective of this study was to test the hypothesis that both in vitro and in vivo, preimplantation embryonic ...

The Transitional Heart: From Early Embryonic and Fetal Development to Neonatal Life. [PDF]
Fetal Diagn Ther, 2020 Formation of the human heart involves complex biological signals, interactions, specification of myocardial progenitor cells, and heart tube looping. To facilitate survival in the hypoxemic intrauterine environment, the fetus possesses structural, physiological, and functional cardiovascular adaptations that are fundamentally different from the neonate.

Inhibin and activin in embryonic and fetal development in ruminants [PDF]
Bioscientifica Proceedings, 2019 Inhibin, activin and follistatin are protein hormones with diverse physiological roles. The involvement of inhibin in the regulation of pituitary FSH production and secretion in adult males and non-pregnant females is well established. However, it is unlikely that inhibin plays a similar role in pregnancy in ruminants.

Expression of cellular oncogenes during embryonic and fetal development of the mouse. [PDF]
Proceedings of the National Academy of Sciences, 1984 Cellular oncogenes are conserved with great fidelity across a broad span of evolution. This avid conservation suggests possible roles in critical physiologic functions. Little, however, is known about their activity in normal cellular processes. In this study, we examined the expression pattern of eight cellular oncogenes during embryonic and fetal ...

Embryonic and Early Fetal Development of the Human Neocortex [PDF]
The Journal of Neuroscience, 2000 Early corticogenesis was studied in human embryos and early fetuses from Carnegie stages 16 to 22 (5–8 gestational weeks) by using immunohistochemistry for Reelin (Reln), calretinin (CR), and glutamic acid decarboxylase (GAD). A first population of Reln-positive cells appears in the neocortical anlage at stage 16 and increases in number at stages 17–18.

Embryonic and fetal development in different genotypes in pigs [PDF]
Bioscientifica Proceedings, 2020 It is widely accepted that uterine capacity, not ovulation rate, is the greatest restraint on litter size in pigs. Recently, the reproductive strategy(s) of the Chinese Meishan pig, a breed which farrows three to five more piglets per litter than US or European pig breeds, has come under intense scrutiny.

Fertilization and normal embryonic and early fetal development
, 2021 The anatomy and physiology of placental and embryonic development is a field where medicine exerts its greatest impact on early pregnancy at present time, and it opens fascinating aspects of embryonic differentiation. Clinical assessment of those stages of growth relies heavily on three-dimensional (3D) and four-dimensional (4D) sonography, one of the ...

Shoulder girdle formation and positioning during embryonic and early fetal human development.
PLoS ONE, 2020 Positional information on the shoulder girdle (the clavicle and scapula) is important for a better understanding of the function of the upper limb in the locomotive system as well as its associated disease pathogenesis.

Generation of naive-like porcine-induced pluripotent stem cells capable of contributing to embryonic and fetal development. [PDF]
Stem Cells and Development, 2013 In pluripotent stem cells (PSCs), there are 2 types: naive and primed. Only the naive type has the capacity for producing chimeric offspring. Mouse PSCs are naive, but human PSCs are in the primed state.
