Cytogenetic Analysis: The stemline chromosome number is triploid with the 2S component occurring at 4.2%. Fifteen markers (M1 and M(15)) occurred in nearly all S metaphases. Spontaneous non-specific dicentrics occurred, but rarely. Unstable markers were also rarely seen. The X was disomic, and N9 was nullisomic.

Comments: The continuous cell line K-562 was established by Lozzio and Lozzio from the pleural effusion of a 53-year-old female with chronic myelogenous leukemia in terminal blast crises. [22609]
The cell population has been characterized as highly undifferentiated and of the granulocytic series. [26059]
Studies conducted by Anderson, et al., on the surface membrane properties led to the conclusion that the K-562 was a human erythroleukemia line. [26060]
The K-562 cell line has attained widespread use as a highly sensitive in vitro target for the natural killer assay. [48829] [1101] [48830]
See Pross, et al. for a detailed analysis of the in vitro assay of NK cells including the mathematics of quantitation of NK cell activity. [48833]
K-562 blasts are multipotential, hematopoietic malignant cells that spontaneously differentiate into recognizable progenitors of the erythrocytic, granulocytic and monocytic series. [26061]
The effect of inducers on sublines derived from the original K-562 cell line have been reviewed by Koeffler and Golde. [867]
Cultures from the ATCC stock have been shown to exhibit this sensitivity for assessing human natural killer activity.
Karyological studies on various K-562 sublines have been classified into three groups (A,B,C) by Dimery, et al. [26063]
The strain obtained by the ATCC most closely resembles the B population. Occurrence of the Philadelphia chromosome, however, was of much lower frequency; none detected in 15 metaphases examined.
The line is EBNA negative.
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Iscove's Modified Dulbecco's Medium, Catalog No. 30-2005. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
