Wilms10M Cells
































General information
Description | The Wilms10M cell line was established from a metastatic lung nodule of a patient with Wilms tumor (nephroblastoma). Like its primary tumor counterpart, Wilms10T, the Wilms10M cell line is characterized by a homozygous deletion of the WT1 gene, resulting in the complete absence of WT1 protein. WT1 is essential for normal kidney development, and its deletion is associated with more aggressive tumor behavior, particularly in metastatic settings. Additionally, Wilms10M cells exhibit loss of heterozygosity (LOH) in the 11p15 chromosomal region, which includes the IGF2 gene, further contributing to the malignant properties of these cells. Wilms10M cells maintain a stable karyotype with no major chromosomal rearrangements apart from the specific deletion of the WT1 region. This cell line, derived from metastatic tissue, is particularly valuable for studying the molecular mechanisms that drive metastasis in Wilms tumor. The cells exhibit mesenchymal characteristics, expressing markers such as vimentin, while lacking epithelial markers like cytokeratin, which is indicative of their origin from the stromal component of the tumor. Research on Wilms10M has focused on the signaling pathways that are active in these metastatic cells. Proteomic analyses have demonstrated the activation of several receptor tyrosine kinases (RTKs), including IGF1R, PDGFRβ, and AXL, which are involved in promoting cell survival, proliferation, and metastatic potential. The downstream MAPK and PI3K/AKT signaling pathways are also activated, playing a key role in maintaining the invasive and metastatic phenotype of Wilms10M cells. Given its metastatic origin, Wilms10M is an essential model for understanding the molecular events underlying Wilms tumor metastasis and for developing targeted therapeutic strategies against metastatic disease. |

Handling
Culture Medium | MSCGM kit (from Lonza) |
---|---|
Passaging solution | Accutase |
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. |
Freeze medium | As a cryopreservation medium, use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress. |

- 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.
