Research Progress in the Immortalization of Animal Cells

Abstract

Abstract:

Cell immortalization refers to breaking through the limitations of primary cell aging, extending cell lifespan, and achieving unlimited cell replication and proliferation through various means and methods, which is a hot and difficult research topic in the current biomedical field. Immortalized cell lines can be used for the development of biological products, exploration of aging mechanisms to extend life, etc. However, due to the limited variety of immortalized cells, relatively difficult immortalization technology, tumor risk, and animal welfare ethics, it still cannot meet the research and developing needs. The purpose of immortalizing cells is not only to permanently preserve the genetic resources of animal cells, but also to provide support for the diagnosis and treatment of various diseases, as well as to develop cell matrix for vaccines. This article reviews the latest progresses in the principles, mechanisms, and methods of immortaling animal cells, providing reference for future biomedical research and applications.

Key words: animal cells, cell immortalizing, immortalization mechanism, immortalization method
