prenatal developmenthuman fetusThe aortic isthmus is a specific feature of fetal circulation. It undergoes regression by becoming wider postpartum. Developmental abnormalities of an isthmus may lead to congenital defects. The aim of this work was a morphometric study of the aortic isthmus in human ...
In our study, the development of the fetal human hypothalamus is presented in stages designated according to the major morphological changes observed in the hypothalamus. 5. Stages of hypothalamic differentiation 5.1. Weeks 9–10 of gestation (first trimester, early post-embryonic period, n=2, CRL...
Haematopoiesis first emerges in human BM at 11–12 weeks after conception1,2, yet almost nothing is known about how fetal BM (FBM) evolves to meet the highly specialized needs of the fetus and newborn. Here we detail the development of FBM, including stroma, using multi-omic assessment of...
However, very little is known about the regulation of IgE production by the fetus and neonate. The lower production of IgE by neonatal B cells has cata- lyzed numerous analyses of B- and T-cell phenotype. Neonatal B-cell expression of CD40 is similar to the adult (12), and responses ...
Development of the glomerulus Specimens of kidney from 20 humanfetuses, ages 1 1/2 to 5 months' gestation, have been studied by light and electron microscopy. Glomeruli of all stages of maturity from the most primitive glomerular anlage to the mature, adult type of g... RL Vernier,A BIRCH...
During this period the cochlear ganglion is separated from the vestibular ganglion, and it is adjacent to the cochlear duct. In embryos of investigated stages fibers of the cochlear ganglion enter the nuclei in the brain.关键词: Spiral Ganglion Humans Embryonic and Fetal Development Pregnancy ...

In human pregnancy, prenatal development, also known asantenatal development, is the development of the embryo following fertilization, and continued as fetal development. By the end of the tenth week of gestational age the embryo has acquired its basic form and is referred to as a fetus. The ...
pregnancy, PHTs derived from distinct pregnancy stages need to be selected based on the specific demands of their experiments. It is crucial to acknowledge that the PHT model remains an in vitro cell model, and it may deviate from actual placental development because the placental structure and ...
The normal development of the basilar part of the occipital bone was divided into five maturity stages (OB-I to OB-V). Microscopic investigation confirmed the macroscopic findings described. For each stage the ventro-dorsal dimension of the occipital bone component was measured (LEN). The stages...
