  • ventral
  • Precursors of inhibitory interneurons transplanted from the medial ganglionic eminence of the ventral embryonic forebrain into the juvenile or adult rodent cortex migrate from the graft site and become dispersed throughout the recipient tissue (shown as small red dots in the transplanted hemisphere in a cross section of the rodent brain, upper left). (sciencemag.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)
  • germ
  • 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. (medicalxpress.com)
  • To pinpoint which-if any-microRNAs influence germ layer formation in early embryonic development, Mercola and his team individually studied most (about 900) of the microRNAs from the human genome. (medicalxpress.com)
  • humans
  • The let-7 RNA was found to be conserved in many species, leading to the suggestion that let-7 RNA and additional "small temporal RNAs" might regulate the timing of development in diverse animals, including humans. (wikipedia.org)
  • larval
  • These groups published back-to-back papers on the lin-4 gene, which was known to control the timing of C. elegans larval development by repressing the lin-14 gene. (wikipedia.org)
  • prenatal development
  • The early appearance of serotonin and its receptors during prenatal development, together with the many effects serotonin exerts during CNS morphogenesis, strongly suggest that serotonin influences the development and maturation of the mammalian brain before it becomes a neuromodulator/neurotransmitter. (pnas.org)
  • cancer
  • MAPK signaling pathways, or chemical networks that involve the enzyme, are critical for normal development, and defects in these pathways can lead to severe developmental disorders and cancer. (princeton.edu)
  • cells
  • They often can be found to have features of embryonic cells. (ucsd.edu)
  • Results published March 9 in the journal Current Biology, however, suggest that competition for the MAPK enzyme among proteins in different pathways influences which signals are sent to cells, establishing a biochemical mode of signal integration that adds a previously unrecognized layer of complexity and control to embryonic development. (princeton.edu)
  • Development takes place in the fallopian tube, as the cells travel towards the uterus. (sciencephoto.com)
  • When the cells fail to associate in a manner that is not part of the normal course of development, severe diseases can occur. (wikipedia.org)
  • control
  • Our findings provide a new window through which to look at epigenetic control," Yeh said, "and how epigenetics and development are unexpectedly tied together by the SUMO/SENP2 system. (redorbit.com)
  • Regulation
  • Accumulating in vitro evidence also indicates that serotonin signaling participates in the regulation of development in many animal phyla before the onset of neurogenesis. (pnas.org)
