• embryo
  • Human embryo development is a complex process. (springer.com)
  • The zygote undergoes rapid mitotic divisions with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of an embryo. (phys.org)
  • The marvelous development of the human embryo should make everyone a creationist, it seems to me, but evolutionists say that the so-called 'gill slits, yolk sac, and tail' are useless evolutionary leftovers (vestiges) that virtually 'prove' we evolved from fish, reptiles, and apes. (sounddoctrine.net)
  • Early on in development, the mass of undifferentiated cells that make up the embryo take the first steps in deciding how to arrange themselves into component parts to eventually go on to form a fully developed body. (thaindian.com)
  • 30 h -Amnion (embryonic membrane around embryo) begins. (backyardchickens.com)
  • The resulting combination of proteins will transform clusters of cells into early embryo tissues that will each develop into multiple fetal and adult tissues later in development (note: this happens after each nucleus becomes wrapped with its own cell membrane). (wikipedia.org)
  • As recently as the 18th century, the prevailing notion in western human embryology was preformation: the idea that semen contains an embryo - a preformed, miniature infant, or homunculus - that simply becomes larger during development. (wikipedia.org)
  • Growth
  • In recent years, Kipps and others have become increasingly interested in the role of ROR1 plays in the growth of cancer - and whether the protein might provide new options for stopping development of the disease. (ucsd.edu)

  • Segmentation is apparently specified by the same gene as in other groups of animals, and is activated in each case, during embryonic development, at the rear border of each segment and in the growth zone of the stub feet. (wikipedia.org)
  • mice
  • For mice, by embryonic day 7.5 (E7.5), MACF1 is expressed in the headfold and primitive streak, and by E8.5 the protein is expressed in neuronal tissues and the foregut. (wikipedia.org)
  • organs
  • One of the first, and arguably most important, steps in development is the allocation of cells into three germ layers-ectoderm, mesoderm , and endoderm-that give rise to all tissues and organs in the body," explains Mark Mercola, Ph.D., professor and director of Sanford-Burnham's Muscle Development and Regeneration Program in the Sanford Children's Health Research Center.

  • Versican is a chondroitin sulfate proteoglycan and a component of the extracellular matrix that has previously been shown to have an important role during the embryonic development of many organs. (washington.edu)
  • liver
  • In this study, versican expression in the head, heart, lung and liver was tracked during development in the mouse. (washington.edu)
  • Quantitative β-GAG immunohistochemistry and mRNA analysis of the embryonic head, liver, and lung had identical patterns of versican expression. (washington.edu)
  • During mouse organogenesis, Jarid2 is involved in the formation of the neural tube and development of the liver, spleen, thymus and cardiovascular system. (wikipedia.org)
