Tumor Model Construction Service for Exosome Functional Research

As small extracellular vesicles containing a variety of biologically active substances, exosomes are almost involved in the entire process of tumor development and are closely related to tumor progression. However, exogenous exosomes can be used as carriers of tumor therapeutic drugs to target anti-tumor components such as loaded nucleic acids, proteins, lipids, and small molecular compounds to tumor cells to achieve tumor cell killing. A large number of studies have shown that natural exosomes or engineered exosomes can treat tumors by inhibiting tumor cell proliferation and metastasis, regulating tumor microenvironment, inhibiting tumor angiogenesis, regulating tumor drug resistance, and activating immune cells. Therefore, exosome therapy is expected to become a new and efficient way of tumor treatment. Experimental animal models have long been used as an important tool for studying human diseases and developing new drugs. Animal models currently available for tumor research mainly include induced tumor animal models, transplanted tumor animal models, and genetically engineered mouse models. These models can be used for screening and efficacy studies of new exosome drugs. Creative Biolabs can provide various tumor animal model construction services and in vivo efficacy evaluation services to help customers study the efficacy and safety of therapeutic exosomes.

Creative Biolabs Tumor Disease Model Library for Exosome Functional Research

We can provide including but not limited to the following tumor disease animal models for exosome functional research.

Tumor Animal Models	Induction Mechanism	Applicable Animals	Model Features
Induced tumor animal models	Under experimental conditions, tumors are induced in animals by using physical, chemical, and biological carcinogens. The most common chemical carcinogens mainly include benzopyrene, methylcholanthracene, benzidine, nitrosamines, and aflatoxins.	Mouse, Rat	The inducing factors and conditions of this model can be controlled artificially, and the inducing rate is much higher than the natural incidence rate.
Cell-line-derived tumor xenograft animal models	Tumor cell lines are transplanted into allogeneic or xenogeneic animals to form tumors. The transplantation site is generally subcutaneous, orthotopic, or systemic injection.	Mouse	This model is often used for anticancer drug screening and efficacy evaluation.
Human tumor tissue xenograft animal models	Fresh tumor tissue from patients is directly inoculated Immunodeficient mic. The site of inoculation is usually subcutaneous, in situ, or systemic injection.	Mouse	This model retains the stromal heterogeneity and histological characteristics of the patient's tumor, can provide an in vivo simulation environment for tumor research, and can more objectively and comprehensively reflect the tumor's response to drug effects.
animal models	Specific genes are knocked out or inserted by using techniques such as transgenic, gene targeting, and conditional gene targeting, resulting in the spontaneous formation of tumors in vivo.	Mouse	This model has great advantages for studying the mechanism of tumorigenesis and tumor immune evasion.
