U87MG Cells
















Insights on the U87MG cell line
Description | The U87MG cell line, established from a human glioblastoma, is one of the most widely utilized cellular models in neurobiological and cancer research. Originating from a malignant tumor of the central nervous system, these cells exhibit many of the hallmark features of glioblastoma multiforme (GBM), including rapid proliferation, high invasiveness, and significant genetic and phenotypic heterogeneity. This makes the U87MG cell line, also referred to as U87 cells, an invaluable tool for exploring the molecular and cellular mechanisms underlying brain tumors, as well as for testing potential therapeutic strategies. In neuroscience and immuno-oncology research, U87MG cells serve as a model to elucidate the cell function and cytotoxicity mechanisms in glioblastoma, including the exploration of NK cell cytotoxicity. The expression of NKG2D ligands on U87 cells and the use of NKG2D antibodies in studies highlight the intricate dynamics between cancer cells and the immune system, particularly NK cells, in the tumor microenvironment. The stemness features of U87 glioblastoma cells, alongside their genetic and phenotypic attributes, are subjects of intense study, aiming to unravel the mechanisms that confer these cells a high degree of plasticity and resistance to conventional therapies. The U87 cell line's exact origin remains somewhat enigmatic, with genetic analyses revealing differences from the original tumor. In summary, the U87 cell line remains a fundamental tool in glioblastoma research, facilitating a deeper understanding of the disease's biology and the quest for more effective treatments. |

Subculturing | Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium. |

- A Gentle Alternative to Trypsin
Accutase is a cell detachment solution that is revolutionizing the cell culture industry. It is a mix of proteolytic and collagenolytic enzymes that mimics the action of trypsin and collagenase. Unlike trypsin, Accutase does not contain any mammalian or bacterial components and is much gentler on cells, making it an ideal solution for the routine detachment of cells from standard tissue culture plasticware and adhesion coated plasticware. In this blog post, we will explore the benefits and uses of Accutase and how it is changing the game in cell culture.
Advantages of Accutase
Accutase has several advantages over traditional trypsin solutions. Firstly, it can be used whenever gentle and efficient detachment of any adherent cell line is needed, making it a direct replacement for trypsin. Secondly, Accutase works extremely well on embryonic and neuronal stem cells, and it has been shown to maintain the viability of these cells after passaging. Thirdly, Accutase preserves most epitopes for subsequent flow cytometry analysis, making it ideal for cell surface marker analysis.
Additionally, Accutase does not need to be neutralized when passaging adherent cells. The addition of more media after the cells are split dilutes Accutase so it is no longer able to detach cells. This eliminates the need for an inactivation step and saves time for cell culture technicians. Finally, Accutase does not need to be aliquoted, and a bottle is stable in the refrigerator for 2 months.
Applications of Accutase
Accutase is a direct replacement for trypsin solution and can be used for the passaging of cell lines. Additionally, Accutase performs well when detaching cells for the analysis of many cell surface markers using flow cytometry and for cell sorting. Other downstream applications of Accutase treatment include analysis of cell surface markers, virus growth assay, cell proliferation, tumor cell migration assays, routine cell passage, production scale-up (bioreactor), and flow cytometry.
Composition of Accutase
Accutase contains no mammalian or bacterial components and is a natural enzyme mixture with proteolytic and collagenolytic enzyme activity. It is formulated at a much lower concentration than trypsin and collagenase, making it less toxic and gentler, but just as effective.
Efficiency of Accutase
Accutase has been shown to be efficient in detaching primary and stem cells and maintaining high cell viability compared to animal origin enzymes such as trypsin. 100% of cells are recovered after 10 minutes, and there is no harm in leaving cells in Accutase for up to 45 minutes, thanks to autodigestion of Accutase.
In summary
In conclusion, Accutase is a powerful solution that is changing the game in cell culture. With its gentle nature, efficiency, and versatility, Accutase is the ideal alternative to trypsin. If you are looking for a reliable and efficient solution for cell detachment, Accutase is the solution for you.
