Human mantle cell lymphoma malignant clone cell strain and construction method and application thereof

Abstract

The invention belongs to the technical field of construction of tumor cell lines, and particularly relates to a tumor malignant clone cell line having important abnormal development disintegrating stage of mantle cell lymphoma, and a construction method and application of the tumor malignant clone cell line. The invention provides a human mantle cell lymphoma malignant clone cell strain containingearly malignant clone cells, is named as a human mantle cell lymphoma malignant clone cell strain JeKo-1-spheroid, and is preserved in China Center for Type Culture Collection (CCTCC), and the preservation number is C2018264. A mature JeKo-1-parental cell strain is used as an induction object, a continuous culture and natural purification methods are used, a malignant clone cell strain containinga mantle cell lymphoma main malignant disintegrating stage is obtained, and the obtained cell strain highly cooperates with primary cells of a patient.

Description

technical field [0001] The invention belongs to the technical field of establishment of tumor cell lines, and in particular relates to a tumor malignant clone cell line with an important abnormal development and differentiation stage of mantle cell lymphoma and an establishment method thereof. Background technique [0002] Tumors are composed of cell groups with malignant clonal proliferation at different stages. Among them, the evolution of malignant clones is the most important to the occurrence and evolution of tumors, especially the early stage clones, which is of great significance for us to further comprehensively and objectively study tumors. The hotspot of tumor research focuses on the evolution of malignant clones between cells in the abnormal stage of differentiation and development, which not only further deepens the understanding of tumor occurrence, but also has a profound impact on tumor diagnosis and treatment, prognosis judgment, and drug development.

AI Technical Summary

Problems solved by technology

The biggest problem in the above research is to establish a single cell component cell line as pure as possible in the early stage, while ignoring the fact that the early malignant clone tumor cells with stemness are also undergoing continuous differentiation, and the malignant clones of each stage of the tumor are mutually differentiated Treated in isolation, this kind of cell model research is somewhat one-sided, and objective research should use cell models that are consistent with malignant clones in vivo as research objects

Moreover, the above studies also show the following disadvantages: difficult to culture, poor cell viability, and difficult to obtain experimentally stable cell lines containing malignant clones in various stages of tumor differentiation, especially in the early stages
