  • Some evidence shows that Myf5 and MyoD are responsible for the development of separate muscle lineages, and are not expressed concurrently in the same cell. (wikipedia.org)
  • Still, the existence of these separate "MyoD-dependent" and "Myf5-dependent" subpopulations has been disputed, with some claiming that these MRFs are indeed coexpressed in muscle progenitor cells. (wikipedia.org)
  • Despite only being present for a few days during embryonic development, Myf5 is still expressed in certain adult cells. (wikipedia.org)
  • These findings highlight the continued public health risk of swine-origin A(H3N2) strains, especially in human populations with low cross-reactive immunity. (cdc.gov)
  • Enriched monolayer precursor cell cultures from micro-dissected adult mouse dentate gyrus yield functional granule cell-like neurons. (mdc-berlin.de)
  • If these structures are manipulated incorrectly, through processes known as chromosomal instability and translocation, the cell may undergo mitotic catastrophe . (wikipedia.org)
  • Semaphorins are a wide family of extracellular regulatory signals with a multifaceted role in cell-cell communication. (biomed.news)
  • Understanding the complete immune cell composition of human neuroblastoma (NB) is crucial for the development of immunotherapeutics. (pklab.org)
  • A significant proportion of clinical studies that are underway involve bone marrow and cord blood stem cells for blood and immune disorders [ 3 ] and cancers. (biomedcentral.com)
  • Together, these data suggest that CXCR4 plays an important role in donor cell engraftment. (biomedcentral.com)
  • We show that CXCR4 expressing cells are important for donor muscle cell engraftment, yet FACS sorted CXCR4-positive cells display decreased engraftment efficiency. (biomedcentral.com)
  • We used the xenotransplant model to show that CXCR4 expression on canine donor muscle cells is also important for cell engraftment, but FACS sorting for CXCR4-positive cells decreased their engraftment efficiency. (biomedcentral.com)
