简单介绍
TF-1a细胞应如何避免细胞污染,细胞污染的种类可分成**、酵母菌、霉菌、病毒和霉浆菌。主要的污染原因为无菌操作技术不当、操作室环境不佳、污染之血清和污染之细胞等。严格之无菌操作技术、清洁的环境、与品质良好之细胞来源和培养基配制是减低污染之*好方法。TF-1a细胞何时须更换培养基?视细胞生长密度而定,或遵照细胞株基本数据上之更换时间,按时更换培养基即可。

TF-1a细胞Comments: TF-1a is a factor-independent variant isolated from the factor-dependent TF-1 cell line (see CRL-2003). [51559]

The cells retain the ability to respond to a variety of cytokines, with a different response pattern from the parental cell line. [51559]

TF-1a, but not TF-1 cells, form colonies in soft agar culture in the absence of any added growth factors, and generate invasive tumors in nude mice. [51559]

There is a slight constitutive activation of the MAP kinase and MEK proteins in TF-1a but not in TF-1 cells. Phenotypically, TF-1 cells are CD34 positive and CD38 positive, whereas TF-1a cells are CD34 positive and CD38 negative. [51559]

TF1-a cells, but not TF-1 cells, are resistant to tumor necrosis factor alpha (TNF-alpha) induced apoptosis.

TF-1a is a model for studying human primitive myeloid progenitor cells and for studying the process of progressive malignant transformation of myeloid cells.

It can be used to study signal pathways involved in the spontaneous and factor-induced growth of the cells.

A culture submitted to the ATCC in April of 1999 was found to be contaminated with mycoplasma. Progeny were cured by a 21-day treatment with BM Cycline.

The cells were assayed for mycoplasma, by the Hoechst stain, PCR and the standard culture test, after a six-week period following treatment. All tests were negative.

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%.

Temperature: 37.0°C

Subculturing: Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density)

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 3 X 10 exp5 viable cells/ml.

TF-1a细胞Maintain cell density between 3 X 10 exp5 and 3 X 10 exp6 viable cells/ml.

Preservation: culture medium 95%; DMSO, 5%

Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2001

recommended serum:ATCC 30-2020

parental cell line:ATCC CRL-2003
