M14 Cells

The M14 cell line is a human melanoma cell line derived from a metastatic skin lesion of an adult patient with melanoma. This cell line is widely used in cancer research, particularly in the study of melanoma biology, tumor progression, and the evaluation of potential therapeutic agents. M14 cells exhibit characteristics typical of malignant melanoma, including the ability to form tumors in immunocompromised mice, making them a valuable tool for in vivo studies in addition to in vitro experiments.
In terms of molecular features, M14 cells have been reported to carry mutations in genes that are frequently altered in melanoma, including the BRAF gene. Specifically, M14 cells harbor the BRAF V600E mutation, which leads to constitutive activation of the MAPK/ERK signaling pathway, promoting cell proliferation and survival. This makes M14 an important model for studying targeted therapies, such as BRAF inhibitors, that are designed to exploit this mutation. Additionally, M14 cells have been utilized in immunotherapy research due to their expression of various melanoma-associated antigens and susceptibility to immune system modulation.
Researchers using the M14 cell line should note that these cells are not suitable for therapeutic applications and are intended solely for research purposes, particularly those focusing on melanoma pathophysiology, drug screening, and the development of new therapeutic strategies. The M14 cell line remains a key resource for advancing our understanding of melanoma and exploring new avenues for treatment.
