  • occurs
  • Myogenesis is the formation of muscle that occurs throughout an animal's development, from embryo to the end of life. (asu.edu)
  • Rh incompatibility occurs when a pregnant woman whose blood type is Rh-negative is exposed to Rh-positive blood from her fetus, leading to the mother s development of Rh antibodies. (asu.edu)
  • genetic
  • Sydney Brenner, H. Robert Horvitz, John E. Sulston, 'for their discoveries concerning 'genetic regulation of organ development and programmed cell death. (livescience.com)
  • In the 1970s, Nusslein-Volhard focused her career on studying the genetic control of development in the fruit fly Drosophila melanogaster. (asu.edu)
  • neural
  • An NTD originates from and is characterized by incomplete closure of the neural tube, which is an organizer and precursor of the central nervous system. (asu.edu)
  • embryology
  • In 1828, while working at the University of Konigsberg in Konigsberg, Germany Karl Ernst von Baer proposed four laws of animal development, which came to be called von Baer's laws of embryology. (asu.edu)
  • These groundbreaking illustrations of the fetus reveal his advanced understanding of human development and demonstrate his role in the vanguard of embryology during the Renaissance. (asu.edu)
  • crucial
  • Wolpert's model has provided crucial theoretical framework for investigating universal mechanisms of pattern formation during development. (asu.edu)
  • demonstrate
  • By systematic knockdown of all putative Smed Wnts in regenerating planarians, we identify Smed-WntP-1 and Smed-Wnt11-2 as the putative posterior organizers, and demonstrate that Smed-Wnt5 is a regulator of neuronal organization and growth. (biologists.org)
  • mammals
  • The Sex-determining Region Y (Sry in mammals but SRY in humans) is a gene found on Y chromosomes that leads to the development of male phenotypes, such as testes. (asu.edu)
  • Driesch
  • These questions, various answers to which constitute the theories of preformation or epigenesis, were lifted out of the realm of speculation up into that of an exact science when first Wilhelm Roux and then Hans Driesch used experimental methods in their research into development. (nobelprize.org)
  • functions
  • Nerve growth factor (NGF) is a signaling protein and growth factor implicated in a wide range of development and maintenance functions. (asu.edu)
  • studies
  • However, although these studies suggest that Wnt proteins might be essential organizers of regeneration in planarians, direct evidence is missing. (biologists.org)
  • period
  • The embryonic period or critical period is when most organ systems form, whereas the fetal period, week eight to birth, involves the growth and modeling of the organ systems. (asu.edu)
  • series
  • In 1951 Viktor Hamburger and Howard Hamilton created an embryonic staging series from a combination of photographs and drawings from other researchers. (asu.edu)
  • Work
  • Indeed, Bonner's work on morphogenesis highlighted synergies between development and evolution long before "evo-devo" became a part of the scientific lingua franca. (asu.edu)
  • study
  • The paper described the results of a study initiated in 1979 on the development of twins raised in different environments. (asu.edu)
