• embryos
  • The aorta-gonad-mesonephros (AGM) is a region of embryonic mesoderm that develops during embryonic development from the para-aortic splanchnopleura in chick, mouse and human embryos. (wikipedia.org)
  • This is the same case in human embryos, where they are first detected at day 27 in the aorta gonad mesonephros region, expand rapidly at day 35, then disappear at day 40. (wikipedia.org)
  • Hanley appears to be the originator of this theory, that half the time when human embryos merge the brain will be one sex, and gonads and body form will be the opposite sex. (wikipedia.org)
  • gonadal
  • A review of the literature establishes that children with intersex disorders who possess a Y chromosome and undescended gonads stand a particularly high risk of having this type of gonadal neoplasm and should be explored. (biomedsearch.com)
  • The gonadal ridge, in turn, develops into a gonad. (wikipedia.org)
  • gland
  • The gonads are controlled by luteinizing hormone and follicle-stimulating hormone, produced and secreted by gonadotropes in the anterior pituitary gland. (wikipedia.org)
  • cortex
  • We illustrate how Pitx2 activity directs asymmetrical gonad morphogenesis by controlling mitotic spindle orientation of the developing gonad cortex and how, by modulating cyclinD1 expression during asymmetric ovarian development, Pitx2 appears to control gonad organ size. (biomedsearch.com)
  • cells
  • The aorta gonad mesonephros region has been shown to harbour multipotent hematopoietic colony-forming unit-spleen (CFU-S) progenitor cells and pluripotential long-term repopulating hematopoietic stem cells (LTR-HSCs). (wikipedia.org)
  • form
  • This means that typically, the brain will form from one embryo, and the gonads from a different one. (wikipedia.org)
  • Role
  • The most significant function of the aorta gonad mesonephros region is its role in definitive haematopoiesis. (wikipedia.org)
  • found
  • LTR-HSC activity was also found in the aorta gonad mesonephros region at a slightly earlier time than in the yolk sac and foetal liver. (wikipedia.org)
  • region
  • The aorta-gonad-mesonephros (AGM) region is an area derived from splanchnopleura mesoderm identified in embryonic humans, mice, and non-mammalian vertebrates such as birds and zebrafish. (wikipedia.org)
  • In contrast to the yolk sac, the extra-embryonic haematopoietic site, the number of CFU-S was much greater in the aorta gonad mesonephros region. (wikipedia.org)
  • At 10 days post coitus (d.p.c.) the aorta gonad mesonephros region was able to initiate and expand definitive haematopoietic stem cell activity, whereas no haematopoietic activity was seen in the yolk sac until 11 d.p.c. (wikipedia.org)
  • Gonads in the abdominal region. (wikipedia.org)
  • human
  • 11-Ketotestosterone Is a Major Androgen Produced in Human Gonads. (sigmaaldrich.com)
  • Design, Participants, and Methods: Expression of cytochrome P450 and 11β-hydroxysteroid dehydrogenase types 1 and 2 (key enzymes involved in the synthesis of 11-KT) were investigated in human gonads. (sigmaaldrich.com)
  • The current study indicates that 11-KT is produced in the gonads and represents a major androgen in human. (sigmaaldrich.com)
