Stable Cell Line Construction Services for Brain Tumors

Stable cell line construction is a crucial aspect of preclinical research, particularly in the study of brain tumors. These cell lines provide a reliable platform for understanding tumor biology, testing therapeutic agents, and developing novel treatment strategies. At Alfa Cytology, we specialize in creating high-quality stable cell lines tailored for brain tumor research.

Introduction to Stable Cell Line for Brain Tumor

Our Services

At Alfa Cytology, we specialize in the development of high-quality stable cell lines tailored for brain tumor research. Our comprehensive services include:

Hybrid clonal cell lines. Gene transfection followed by direct screening with resistance drugs. The screened cells express both the resistance gene and the target gene but contain a variety of different cell clones. The location of target gene integration and expression varies between clones. It has the advantage of relatively rapid screening and low cost.
Monoclonal cell lines. A cell line obtained from the amplification of a single cell containing a stably integrated exogenous fragment. The expression of the target gene at the site of integration is highly uniform for each cell, but some phenotypes may be lost. Monoclonal cell screens are often recommended for cell lines that require cell sublocalization experiments, are difficult to infect, and have low expression rates.

Some of the Stable Cell Lines that Have Been Constructed

Name	Stable cell lines
Human brain astrocytoma	U-87 MG-Luc-mNeonGreen-Puro
Human glioma cells	U251-CMV-EGFP-Puro
Human neuroblastoma cells	SK-N-SH-EGFP-Puro
Mouse brain neuroma cells	Neuro-2a-EGFP-Puro Neuro-2a-CMV-Puro

Technical Advantages

Excellent seed cells. Low generation and no contamination.
Stable production process. Strict screening and target gene expression verification system.
No loss of cell viability. Rigorous evaluation of cell proliferation viability for 5 consecutive generations after line establishment.
Cell line quality assurance. RT-qPCR validation to ensure expression level.

Applications

A long-term study of gene function in target cells, we can reduce the cost of frequent transfection or virus packaging by establishing stable cell lines to facilitate experimental studies.
Some proteins have extremely long half-lives, and transient RNA can only interfere with expression and cannot remove the already expressed target protein, we can achieve better gene interference effects by building stable cell lines.
Transient will introduce extremely high copy number expression, leading to inaccurate experimental results due to human factors, we build stable cell lines that can help to screen cells with appropriate copy numbers for experimental studies.
Those that require an inducible expression system are mainly some lethal genes or those that require spatiotemporal expression. Those that need to use cells for animal experiments, such as nude mice tumorigenesis, etc. We can establish stable cell lines for all of them.

Case Study - SF-295 Xenograft Model

Model Introduction

The SF-295 xenograft model offers a robust preclinical platform for investigating glioblastoma multiforme (GBM) biology and evaluating the efficacy of novel therapeutic agents. SF-295 is a human glioblastoma cell line originally derived from a malignant glioblastoma tumor. It is widely used in cancer research due to its characteristic GBM features, including aggressive growth, resistance to apoptosis, and invasive potential. This model is particularly valuable for studying the tumor microenvironment, hypoxia, and the efficacy of various therapies such as radiotherapies and novel DNA-targeting compounds.

Model Information

Model: SF-295 Xenograft Modell
Animals: NOD-Scid Mice
Age: 7-8 Weeks

Cancer Type: Glioblastoma Multiforme (GBM)
Weight: 18-22 g

Model Construction

The model is typically established by subcutaneously implanting human SF-295 glioblastoma cells into the flank of immunocompromised mice. Cell inoculum is 1×10⁶ cells/mouse in 100 µL injection volume with 50% matrigel solution. Tumor growth is monitored regularly by caliper measurements to track progression.

Model Data

Tumorigenicity: SF-295 cells exhibit high tumorigenic potential in immunocompromised mouse strains, leading to consistent and reproducible model establishment.
Growth Kinetics: Tumor growth is progressive and measurable. By day 5 post-inoculation, tumors reach volumes ranging from 100-250 mm³, which is suitable for initiating therapeutic dosing. Drug A exhibited tumor-inhibitory effects relative to the control.
