簡單介紹

RW.4細胞應如何避免細胞污染,細胞污染的種類可分成**、酵母菌、霉菌、病毒和霉漿菌。主要的污染原因為無菌操作技術不當、操作室環境不佳、污染之血清和污染之細胞等。嚴格之無菌操作技術、清潔的環境、與品質良好之細胞來源和培養基配制是減低污染之*好方法。RW.4細胞何時須更換培養基?視細胞生長密度而定,或遵照細胞株基本數據上之更換時間,按時更換培養基即可。

Applications: Gene knock-out - RW.4 cells have been used to create a number of different gene knock-out mice. [90419] [16173329]

Gene knock-in - RW.4 ES cells were used to create a knock-in mouse subline for use as a model of acute promyelocytic leukemia (APL). [16173330]

Differentiation - RW.4 ES cells can be induced by staurosporine (STS) to differentiate into neurons and astrocytes from embryoid bodies. [16173319] [16173331]

RW.4細胞ESC Proliferation - RW.4 cells have been used to study the effects of statins, cholesterol-lowering drugs, on ESC self-renewal, proliferation and differentiation.

Age: embryo, blastocyst

Gender: male

Comments: The cells stain positive for pluripotency markers and alkaline phosphatase activity and RW.4 has been shown to be germline competent.

Propagation: ATCC complete growth medium: Mouse ES Cell Basal Medium

Atmosphere: air, 95%; carbon dioxide (CO2), 5%

Temperature: 37.0°C

Subculturing: ATCC recommends culturing RW.4 on mouse embryonic fibroblasts (MEFs) that have been mitotically arrested by either irradiation or treatment with mitomycin-C. RW.4 cells have been cultured on irradiated or mitomycin-C treated MEF (CF-1) (ATCC SCRC-1040.1 or SCRC-1040.2a).Feeder cells should be initiated 24-48 hours prior to inoculating with embryonic stem (ES) cells layer at approximately 5.5 X10(4) feeder cells/cm2.

Protocol: Volumes used in this protocol are for 75 sq cm flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. Subculture the cells every 1 to 2 days. If the colonies are close to or touching each other the culture is overgrown. Overgrowth will result in differentiation. RW.4細胞Make sure that sufficient number of flasks pre-plated with MEF feeder layers are prepared in advance to support frequent passage of the ES cells.Pre-warm media and Trypsin/EDTA to 37°C before adding to cells.

Remove and discard culture medium.

Briefly rinse the cell layer with Ca++/Mg++ free Phosphate Buffered Saline (ATCC SCRR-2201 to remove all traces of serum which contains trypsin inhibitor.

Add 2.0 to 3.0 ml of 0.25% (w/v) Trypsin-0.53 mM EDTA (ATCC ? 30-2101) solution to flask and observe cells under an inverted microscope . After about one minute the ES colonies will dissociate and all cells will detach.

Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting several times with a 10 ml pipette in order to dissociate the cells into a single-cell suspension.

Transfer cell suspension to a centrifuge tube and spin at approximately 125 X g for 5 to 10 minutes.

Discard supernatantand resuspend the cell pellet in fresh growth medium. Add appropriate aliquots of the cell suspension to culture vessels with feeder layer. An inoculum of 3 X 104 to 5 X 104 viable cells/cm2 is recommended.

Incubate cultures at 37°C.
