Permits/Forms: In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material. Anyone purchasing ATCC material is ultimay responsible for obtaining the permits. Please click here for information regarding the specific requirements for shipment to your location.
Restrictions: The original U-937 cell line was established by Dr. K. Nilsson's laboratory in 1974 and he has requested the following: （1） In all papers reporting any use of this cell line or any derivatives thereof a direct reference should be made to Sundstrom and Nilsson （Int. J. Cancer 17: 565-577, 1976）. （2） Any proposed commercial use of the cells should be negotiated with Professor Kenneth Nilsson, Rudbeck Laboratory, SE-751 85 Uppsala, Sweden. （3） No distribution of any of the cells or sublines derived therefrom should be made to third parties; （4） The cells should be used for non-clinical, non-commercial research only.

Comments: The U-937 cell line was derived by Sundstrom and Nilsson in 1974 from malignant cells obtained from the pleural effusion of a patient with histiocytic lymphoma.
Studies since 1979 have shown that U-937 cells can be induced to terminal monocytic differentiation by supernatants from human mixed lymphocyte cultures,
phorbol esters, vitamin D3, gamma interferon, tumor necrosis factor （TNF） and, retinoic acid.
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%. [40484]
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.
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Atmosphere: air, 95%; carbon dioxide （CO2）, 5%
Temperature: 37.0°C
Subculturing: Protocol: Cultures can be maintained by the addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 1 to 2 X 10（5） viable cells/ml.
Interval: Maintain cell density between 1 X 10（5） and 2 X 10（6） viable cells/ml.
Medium Renewal: Add fresh medium every 3 to 4 days （depending on cell density）
Preservation: Freeze medium: Complete growth medium supplemented with 5% （v/v） DMSO
Storage temperature: liquid nitrogen vapor phase
Related Products: Recommended medium （without the additional supplements or serum described under ATCC Medium）:ATCC 30-2001
recommended serum:ATCC 30-2020
