  • Biology
  • Here, we have investigated mitochondrial biology and energy metabolism in human embryonic stem cells (hESCs) and hESC-derived neural stem cells (NSCs). (biologists.org)
  • Taken together, our developmental model provides an understanding of the metabolic transition from hESCs to more quiescent somatic cell types, and supports important roles for mitochondria and secretion in hESC biology. (biologists.org)
  • Obtaining a more complete understanding of the biology of pluripotent cells is important for maximising the benefits from these areas. (biologists.org)
  • Due to its mitogenic activity, PDGF is useful as an important component of a defined medium for the growth of mammalian cells in culture, making it a valuable research reagent with multiple applications in the study of animal cell biology. (google.com.au)
  • species
  • Although stem cells collectively in vivo might be expected to rely primarily on anaerobic glycolysis for ATP supply, to minimise production of reactive oxygen species, we show that in vitro this is not so: hESCs generate an estimated 77% of their ATP through oxidative phosphorylation.

  • In avian species, however, the means by which germ cells are defined remain to be elucidated. (omicsonline.org)
  • Avian species are optimal vertebrates in which to examine germ cell development during embryogenesis , because of their oviparity. (omicsonline.org)
  • The amount of time that oogonia multiply by mitosis is not species specific. (wikipedia.org)
  • Cellular
  • Most of the cellular resources in a neuron are devoted to communicating and carrying electrochemical messages to other nerve cells. (scienceabc.com)
  • Cellular organization refers to the components of a cell and how these individual parts are arranged within the cell. (reference.com)
  • For example, typical skin cells are microscopic and oval in shape, while peripheral nerve cells can have long cellular processes that may stretch for long distances. (reference.com)
  • The proteins produced by a particular cell type also vary widely, though many proteins essential to cellular maintenance and reproduction are common to most cell types. (reference.com)
  • It contains the DNA-related functions of the large cell in a smaller enclosure to ensure close proximity of materials and increased efficiency for cellular communication and functions. (news-medical.net)
  • Due to the larger size of the eukaryotic cells, confining certain cellular process to a smaller area also increases the efficiency of functions by improving communication and movement within the cell. (news-medical.net)
  • Additionally, these cells might yield insights into the processes underlying cellular senescence, cancer and ageing ( Zeng, 2007 ). (biologists.org)
  • synthesis
  • Using antibodies to detect plant DNA synthesis requires cell wall digestion, and the enzymes used often contain impurities that can decrease the reliability of the assay. (thermofisher.com)
  • maturation
  • For several primary oocytes that complete meiosis I each month, only one or a few functional oocyte, the dominant follicles, completes maturation and undergoes ovulation. (wikipedia.org)
  • occur
  • If its wing were injured, MITOSIS would occur to repair the injury. (prezi.com)
  • We demonstrate that shoot meristematic activity can occur in the dark through the manipulation of auxin and cytokinin activity as well as through the activation of energy signaling, both targets of photomorphogenesis action, but the organ developmental outcomes differ: while TOR-dependent energy signals alone stimulate cell proliferation, the development of a normal leaf lamina requires photomorphogenesis-like hormonal responses.

  • Genetic
  • Which part of the cell contains genetic information? (reference.com)
  • This genetic material needed to regulate cell function and encodes the information which is passed onto progeny. (news-medical.net)
  • Changes in mitochondrial regulation might also be driven by genetic developmental programmes, reflecting the typical energy requirements of these cell types in vivo as opposed to the energy requirements in culture. (biologists.org)
  • vivo
  • Since heteroaromatic and aromatic carboxylic acids do not normally undergo decarboxylation in vivo (Caldwell, 1982), it can be assumed that oxidation of the furan ring system of furoic acid precedes the loss of carbon dioxide. (inchem.org)
  • Quiescent
  • Progenitor cells in the adult organism, such as multipotent neural stem cells (NSCs), must possess the unique properties of long-term viability and self-maintenance, while remaining in what is typically a quiescent state. (biologists.org)
