  • these primary liquid cultures (100 mL) were incubated for approximately three days in an orbital incubator under continuous illumination at nominal temperatures in the range 21 to 25 °C. These primary cultures provided an inoculum for use in the test (see protocol deviations) in the log phase of growth, characterised by a cell density of 2.19 x 106 cells/mL. (europa.eu)
  • What are the challenges of culturing primary cells compared to established cell lines? (coleparmer.com)
  • Culturing primary cells presents unique challenges compared to established cell lines. (coleparmer.com)
  • Most freshly isolated, primary cell cultures undergo senescence, the process by which cells stop dividing after undergoing a certain number of cell divisions. (atcc.org)
  • These best practices form the basis of several cell culture guides , webinars , and video tutorials that detail the initiation, expansion, and cryopreservation of continuous cell lines, primary cells, hTERT-immortalized primary cells, and organoids. (atcc.org)
  • The present invention provides a simple and robust human liver cell-based system in which persistent hepatitis C infection, persistent hepatitis B infection or ethanol exposure induces a clinical Prognostic Liver Signature (PLS) high-risk gene signature. (sumobrain.com)
