2LMP Xenograft Model Service for Breast Cancer

The 2LMP xenograft model serves as a vital tool for evaluating the efficacy of novel therapeutics against aggressive basal-like breast cancer subtypes. Alfa Cytology provides comprehensive, high-quality 2LMP xenograft model services, leveraging our extensive expertise in in vivo oncology research to accelerate your preclinical drug development programs.

Overview of 2LMP Xenograft Model for Breast Cancer

The 2LMP cell line is a specialized subclone of the human breast cancer cell line MDA-MB-231, particularly recognized for its application in studying basal-like breast cancer (BLBC). These tumors are characterized by their aggressive clinical behavior, high metastatic potential, and poor differentiation, often lacking estrogen receptor (ER), progesterone receptor (PR), and HER-2 amplification.

In research settings, the 2LMP xenograft model is frequently employed to study the role of cancer stem cells (CSCs) and resistance mechanisms to cytotoxic agents. By orthotopically implanting these cells into immunocompromised mice, researchers can create a physiologically relevant model to evaluate targeted therapies.

Cell Line Information: 2LMP

The 2LMP cell line is a key model in the study of triple-negative breast cancer (TNBC) and basal-like phenotypes. The following table provides the essential biological characteristics of this cell line.

Our Services

Alfa Cytology provides a fully integrated, turnkey solution for the 2LMP Xenograft Model Service. Our dedication to quality begins with rigorous cell line authentication and mycoplasma testing. We manage every critical step of the preclinical journey—from standardized orthotopic implantation protocols, in-life monitoring, tumor measurement, to comprehensive endpoint analyses. Leveraging our oncology expertise, we deliver robust data packages tailored to accelerate your breast cancer drug discovery programs.

Workflow of 2LMP Xenograft Model Construction

At Alfa Cytology, we follow a rigorous and standardized protocol to ensure high success rates and reproducibility of 2LMP xenograft models. Our typical workflow includes the following six key steps:

1. Cell Culture and Preparation: 2LMP cells are cultured in vitro in optimized media to ensure they are in the log phase of growth. Prior to implantation, cells are harvested, and viability is confirmed (typically >95%) using automated cell counters.
2. Animal Selection and Acclimatization: We select appropriate immunocompromised mouse strains (e.g., BALB/c Nude or NSG) based on study objectives. All animals undergo a 1-week acclimatization period in our SPF-grade animal facility to minimize stress.
3. Formulation of Cell Suspension: The 2LMP cells are resuspended in a mixture of phosphate-buffered saline (PBS) and a basement membrane matrix (such as Matrigel) at a specific ratio. This ensures optimal cell attachment and promotes efficient in vivo tumor formation.
4. Orthotopic Implantation: Under anesthesia, a precise volume of the cell suspension is injected orthotopically into the mammary fat pad of the mice. This localized implantation mimics the natural tumor microenvironment of breast cancer, allowing for more clinically relevant results.
5. Monitoring & Measurement: Once tumors become palpable, their growth is monitored 2-3 times per week. We use digital calipers to measure the length and width of the tumors to track volume and progression. Animal body weight is also recorded regularly to assess overall health and treatment tolerability.
6. Data Analysis and Reporting: Upon study completion, we perform comprehensive data analysis, including tumor growth curves, inhibition rates (TGI%), and survival analysis. Detailed reports with high-resolution images and statistical validation are then delivered to our clients.
