  • In contrast, all the supporting and Schwann cells are derived from neural crest cells, possibly from the VIIth nerve ganglion to which the vestibulocochlear ganglion is initially attached. (medscape.com)
  • They are derived by a targeted mechanism from the cell endocytic compartment and are formed and stored within the intracellular multivesicular bodies (MVBs). (spandidos-publications.com)
  • Initially it was thought to be the only suicidal mechanism cells possess. (sciencedaily.com)
  • The researchers also found that AOH1996 made cancer cells more susceptible to cancer treatments that cause DNA or chromosomal damage, suggesting that it could be a useful tool in combination therapies. (newatlas.com)
  • Cell division is central to life of all cell and is essential for the perpetuation of the species. (studyinnovations.com)
  • however, processes aiding cell survival have not been well understood. (sciencedaily.com)
  • The survival of an organism whether single cell or multicellular, plant or animal, depends largely on its ability to receive and respond to stimuli such as chemicals, odours, light and sound, together with cell damaging agents and pathogens presented by the environment. (bscb.org)
  • Two processes take place during cell reproduction. (studyinnovations.com)
  • They are bipolar cells, because they have 2 sets of processes, or fibers, that extend from opposite ends of the cell bodies. (medscape.com)
  • In males, WBV resulted in a significant reduction in spermatids and circulating prolactin levels, elevation in number of males having higher circulating testosterone concentrations, and marked alterations in levels of transcripts associated with oxidative stress, inflammation, and factors involved in regulating the cell cycle. (cdc.gov)
  • But to Zhang's surprise, the loss of CRH in those cells affected not only hormone secretion, but also dramatically reduced anxiety behaviors (vigilance, suspicion, fear) in the mice. (neurosciencenews.com)
  • The fibers of the cochlear nerve originate from an aggregation of nerve cell bodies in the spiral ganglion, located in the modiolus of the cochlea. (medscape.com)
  • The longer central fibers, also called the primary auditory fibers, form the cochlear nerve, and the shorter, peripheral fibers extend to the bases of the inner and outer hair cells. (medscape.com)
  • Only about 30,000 of these fibers exist, and the greater number of them-about 95%-innervate the inner hair cells. (medscape.com)
  • It is one step forward in the fight with diseases associated with unnecessary cell death or long-lived abnormal cells. (sciencedaily.com)
