Comments: Studies since 1979 have shown that U-937 cells can be induced to terminal monocytic differentiation by supernatants from human mixed lymphocyte cultures,
The cells are negative for immunoglobulin production and Epstein-Barr virus expression.
The cells express the Fas antigen, and are sensitive to TNF and anti-Fas antibodies.
In 1994, PCR and cytogenetic analyses showed that a number of stocks of U-937 were contaminated with the human myeloid leukemia cell line, K-562.
In the earliest stocks available, the level of contamination was 0.6%.
Distribution was discontinued in March 1994, except if required for patent purposes.
Anyone who wishes to receive a sample of this original material should contact the Head of the ATCC Patent Depository.
A stock of CRL-1593 found to be free of K-562 was propagated continuously for 8 weeks and tested weekly by PCR.
Distribution and seed stocks give DNA profiles characteristic of U-937 only.
Such preparations are now offered as authentic U-937 (ATCC CRL-1593.2) and are believed to be free of second subpopulations.
