U-87 MG Cell Line

General Information
Organism Homo sapiens, human
Cell Line Description U-87 MG (Uppsala 87 malignant glioma) is one of the most widely used human cell lines in brain cancer research. Originally established at Uppsala University in 1966, it originated from a malignant glioma in a 44-year-old male patient. These cells exhibit an epithelial-like morphology, growing in an adherent monolayer and often forming loose cell clusters. Although genomic analysis indicates differences between the widely distributed ATCC/ECACC commercial strains and the original Uppsala tumor, this cell line remains the gold standard model for studying the molecular mechanisms of glioblastoma multiforme (GBM) due to its well-defined growth pattern and high invasiveness.

Mutations Homozygous PTEN mutation/deletion; NF1 heterozygous mutation; TERT promoter mutation; typically IDH1 wild-type.
Markers Expressed NKG2D ligands; ICAM-1 (enhanced by retinoic acid); GFAP expression (variable, often decreased in late passages).
Mycoplasma Test Negative
Culture Conditions and Handling
Subculturing 1. Remove and discard the culture medium.
2. Gently rinse the cell layer with calcium- and magnesium-free PBS buffer to remove residual serum.
3. Add 2.0 to 3.0 mL of 0.25% (w/v) trypsin-0.53 mM EDTA solution (for T75 culture flasks).
4. Observe under an inverted microscope until the cell layer disperses (usually 5 to 15 minutes). Do not tap or shake the culture flask to avoid cell clumping.
5. Add 6.0 to 8.0 mL of complete culture medium and gently aspirate the cells using a pipette.
6. Centrifuge the cell suspension at 125 x g for 5 to 10 minutes.
7. Resuspend the cell pellet in fresh complete culture medium and aliquot into new culture containers.
Medium Renewal 2 to 3 times per week.
Subcultivation Ratio A split ratio of 1:2 to 1:5 is recommended.
Culture Medium EMEM (Eagle's Minimum Essential Medium) + 10% Fetal Bovine Serum (FBS) + 1 mM Sodium Pyruvate + 1% Non-Essential Amino Acids (NEAA).
Culture Conditions Atmosphere: Air, 95%; CO2, 5%; Temperature: 37℃
Cryopreservation 90% to 95% complete growth medium supplemented with 5% to 10% (v/v) DMSO.
