U2OS Cells: A Versatile Model for Cancer Research and Cellular Biology.

 U2OS cells, derived from human osteosarcoma, have become an essential cell line for cancer research, cell biology, and drug screening. Their rapid growth and adaptability make them a preferred choice for researchers studying cancer mechanisms, cell signaling, and therapeutic responses. This article explores the biological features, culturing methods, and applications of U2OS cells, with a special emphasis on the high-quality U2OS cells offered by Cytion.

The Origin and Key Features of U2OS Cells

U2OS cells were isolated from human osteosarcoma, a type of bone cancer. These cells are characterized by their rapid proliferation, high genetic instability, and epithelial-like morphology, which mirrors many features of cancer cells.

Key features of U2OS cells include:

• Species: Human

• Tissue of Origin: Osteosarcoma (bone cancer)

• Morphology: Epithelial-like, adherent, fibroblast-like

• Doubling Time: Approximately 24 hours

• Recommended Medium: DMEM or RPMI-1640 with 10% FBS

The U2OS cell line is a crucial model for investigating the biology of bone cancer and related cellular processes, including cell cycle regulation and DNA repair.

Culturing U2OS Cells

U2OS cells are easy to grow and maintain, making them ideal for use in both basic research and drug discovery.

Culturing guidelines:

• Seeding Density: 1–2 x 10^4 cells/cm²

• Subculture Ratio: 1:3 to 1:5 every 2–3 days

• Incubation Conditions: 37°C, 5% CO2

• Cryopreservation: 90% FBS + 10% DMSO

These cells are highly adaptable to gene editing protocols, making them an excellent choice for CRISPR/Cas9 applications and stable cell line generation.

Applications of U2OS Cells

1. Cancer Research

U2OS cells are primarily used to study the molecular mechanisms of osteosarcoma, tumor progression, and therapeutic strategies for bone cancer.

2. Cell Cycle and DNA Repair Studies

U2OS cells are ideal for studying cell cycle regulation, DNA damage response, and repair mechanisms, particularly in the context of cancer and genetic instability.

3. Drug Screening and Toxicity Testing

These cells are a valuable platform for evaluating the efficacy of anti-cancer drugs and therapeutic compounds. Their responsiveness to various treatments accelerates preclinical testing.

4. Gene Editing and Functional Genomics

Thanks to their ease of transfection and stable integration of genetic modifications, U2OS cells are widely used in functional genomics, gene expression studies, and CRISPR experiments.

5. Cellular Mechanisms and Signal Transduction

U2OS cells are used to investigate various cellular signaling pathways, such as those involved in apoptosis, cancer metastasis, and autophagy.
