The K562 cell line is a widely used model system in biomedical research, particularly in the fields of cancer biology, immunology, and cell signaling. This cell line was first established in the 1970s from the blood of a patient with chronic myeloid leukemia (CML) in blast crisis. Since then, K562 cells have been extensively characterized and have become a valuable tool for understanding the molecular mechanisms underlying various cellular processes. In this article, we will delve into the secrets of the K562 cell line, exploring its origins, characteristics, and applications in scientific research.
Origins and Characteristics of K562 Cells
K562 cells were derived from the peripheral blood of a 53-year-old female patient with CML in blast crisis. The cell line was established by Lozzio and Lozzio in 1975 using a modified Eagle’s medium supplemented with fetal bovine serum. Initially, the cells were thought to be of erythroid origin, but later studies revealed that they exhibit a more immature, blast-like phenotype. K562 cells are known for their ability to grow indefinitely in culture, making them an ideal model system for studying cellular processes. They are also highly sensitive to various stimuli, including cytokines, chemokines, and pharmacological agents, which has led to their widespread use in signaling studies.
Cellular Properties of K562 Cells
K562 cells exhibit several distinct cellular properties that make them useful for research purposes. They are capable of undergoing apoptosis, or programmed cell death, in response to various stimuli, including DNA damage and cytokine deprivation. Additionally, K562 cells can be induced to differentiate into more mature cellular phenotypes, such as megakaryocytes or erythrocytes, using specific chemical agents or growth factors. This property has led to the use of K562 cells in studies of cellular differentiation and development. Furthermore, K562 cells have been shown to express a range of cell surface receptors, including those for cytokines, chemokines, and growth factors, making them a valuable tool for studying cell signaling pathways.
| Cellular Property | Description |
|---|---|
| Apoptosis | Programmed cell death in response to DNA damage or cytokine deprivation |
| Cellular Differentiation | Ability to differentiate into more mature cellular phenotypes, such as megakaryocytes or erythrocytes |
| Cell Surface Receptors | Expression of receptors for cytokines, chemokines, and growth factors |
