概要：MC38 cells are a murine cell line extensively utilized as a model for colorectal carcinoma research.
Originating from a colon adenocarcinoma in a C57BL/6 mouse, these cells exhibit a high mutational burden, making them particularly sensitive to immune checkpoint immunotherapy.
Notably, they have shown responsiveness to endogenous CD8+ T cell attacks against neoantigens, highlighting their value in studying immune interactions within tumor environments.
MC38 cells are characterized by their adherence and fibroblast-like morphology, enabling them to form tumors and metastases in syngeneic C57BL/6 or immunocompromised mice, providing a dynamic system for in vivo studies.
The MC38 murine colon carcinoma model is recognized for its immunological responsiveness, rendering it an effective platform for evaluating immunotherapies, including radiation, checkpoint inhibitors, and other novel treatments.
This models relevance is further underscored by its expression of specific colon markers such as claudin-1 and SATB, which are critical for investigating the genomic and epigenomic underpinnings of colorectal adenocarcinoma and for identifying potential treatment avenues.
Comparatively, MC38 and another murine colorectal cancer cell line, CT26, contain clinically significant mutations but differ in their engraftment fidelity in orthotopic implantation studies.
MC38s doubling time is approximately 20 hours, indicating rapid growth, which, coupled with its immunological characteristics, makes it a versatile tool for cancer research, especially in the context of colorectal adenocarcinoma.
