(wikipedia.org)
  • The term somatic refers to embryos developing asexually from vegetative (or somatic) tissue. (unja.ac.id)
  • Tissue-specific stem cells (also known as Somatic Stem Cells) that appear during fetal development and remain in the body throughout life. (bvsalud.org)
  • In humans, the multiple differentiated cell states are normally stable and inherited through cell division. (lu.se)
  • Utilization of iPSCs in science and medicine in place of ESCs BMP2 eliminates the controversy of embryo utilization to derive stem cells, overcoming the challenges of PF-4136309 using non-ethical sources thereby. (bibf1120.com)

  • Phenotypic correlations of somatic cells and yield were negative. (umn.edu)
  • Also, the transfected host cell undergoes a phenotypic conversion and expresses the changed cell phenotype [41] steadily. (bibf1120.com)
  • Aim: to catalyse our study of the field by discovering somatic variants, developing tools and resources to study them, and improving our ability to analyse, interpret, and organise them in different biological and clinical contexts. (chinmayaias.com)
  • A series of marsupial-eutherian somatic cell hybrids was produced by fusion between lymphocytes from the red kangaroo (Macropus rufus) and HPRT-deficient mouse cells. (edu.au)
  • Stem cells reside in niches that provide signals to maintain self-renewal, and differentiation is viewed as a passive process that depends on loss of access to these signals. (ucl.ac.uk)
  • Here, we demonstrate that the differentiation of somatic cyst stem cells (CySCs) in the Drosophila testis is actively promoted by PI3K/Tor signaling, as CySCs lacking PI3K/Tor activity cannot differentiate properly. (ucl.ac.uk)
  • Thus, we show that somatic cell differentiation is controlled by PI3K/Tor signaling downstream of InR and that the local production of positive and negative InR signals regulates the differentiation niche. (ucl.ac.uk)
  • Furthermore, we showed that Sirt6-null iPS-like cell line has intrinsically a differentiation defect even though the establishment of normal self-renewal. (biomedcentral.com)
  • During the preparation of our manuscript, another group reported that Sirt6 knockout ES cells skewed towards neuroectoderm differentiation [ 20 ]. (biomedcentral.com)
  • However, once cells are committed to a specific fate, it is critical to restrict the activity of such factors to enable differentiation. (bvsalud.org)
  • The U.S. government has for now invested $140 million in a SMaHT-led effort to characterise somatic variants in 10-15 tissues from 150 post-mortem samples obtained from deceased individuals. (chinmayaias.com)
  • Somatic gene therapy represents mainstream basic and clinical research, in which therapeutic DNA (either integrated in the genome or as an external episome or plasmid) is used to treat disease. (omicsonline.org)
  • Therefore, repeat interruptions have clinical importance for disease course in DM1 patients due to stabilizing effect on DMPK expansions in somatic cells. (figshare.com)
  • Somatic plant cells are terminally differentiated and can regain totipotency and initiate embryo development under appropriate conditions. (unja.ac.id)
  • Somatic cells can be inefficiently and stochastically reprogrammed into induced pluripotent stem (iPS) cells by exogenous expression of Oct4 (also called Pou5f1), Sox2, Klf4 and Myc (hereafter referred to as OSKM). (umn.edu)
  • Cells are collected from donor (a) and cultured in vitro (b). (biomedcentral.com)
  • While apoptosis in GBM cells was successfully induced in vitro, the effect of the SPION-TWEAK complex on normal somatic cells and the effect of external environments on the SPION biopolymer is currently being evaluated. (umwrcd.net)
  • Specifically, in vitro endothelial cells, a common somatic cell type used in the lining of blood and lymph vessels, were subjected to the SPION-TWEAK complex in the presence and absence of a magnetic field. (umwrcd.net)

  • Recently, superparamagnetic iron-oxide nanoparticles (SPIONs) bound to a TWEAK ligand have been proposed to specifically target glioblastoma cells at their Fn-14 receptor by inducing cellular death of the cancerous cells through the disruption of the membrane when exposed to a magnetic field. (umwrcd.net)
  • This is great news if the spions are non-toxic to non-cancerous cells. (umwrcd.net)
  • Those species with a separation between sterile somatic cells and a germline are called Weismannists. (wikipedia.org)
  • However, somatic cloning has been inefficient in all species in which live clones have been produced. (biomedcentral.com)
  • The NADPH produced from isocitrate dehydrogenase 1 is involved in the breakdown of fats for energy, and it also protects cells from potentially harmful molecules called reactive oxygen species. (medlineplus.gov)
  • We also molecularly defined the development of Sertoli, Leydig and peritubular myoid cells during the perinatal period, allowing us to identify candidate signaling pathways acting between somatic and germ cells in a stage-specific manner during the perinatal period. (biologists.com)
