		Isolation:	Isolation date: 2004
	
	
		Applications:	Irradiated cells for use as feeder layer
	
	
		Age:	14 days gestation embryo
	
	
		Gender:	male and female mixed
	
	
		Comments:	These cells are provided to be used as feeder cells to support the growth of stem cells in the undifferentiated state. They have been irradiated with 10,000 rads and will not replicate. MEF (CF-1) IRR細胞The cells will begin to deteriorate in 7 to 10 days after plating. Once the feeder cells have attached, the culture medium can be changed to accommodate the cells to be supported. It is recommended that the feeder cells be plated 24 hours before use at 4 to 5 X 10(6) cells per T75 flask in order to obtain a 100% confluent monolayer for stem cells growth.
	
	
		Propagation:	ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium:
	
	
		fetal bovine serum to a final concentration of 15%
	
	
		
	
	
		Atmosphere: air, 95%; carbon dioxide (CO2), 5%
	
	
		Temperature: 37.0°C
	
	
		Subculturing:	Protocol: Establishing and maintaining your culture: To insure the highest level of viability, be sure to warm media to 37?C before using it on the cells. Flasks do not need to be coated before plating MEFs.
	
	
		Thaw the vial by gentle agitation in a 37?C water bath. To reduce the possibility of contamination, keep the O-ring and cap out of the water.
	
	
		Remove the vial from the water bath as soon as the contents are half way thawed (approximately 90 seconds), and decontaminate by dipping in or spraying with 70% ethanol.MEF (CF-1) IRR細胞 All of the operations from this point on should be carried out under strict aseptic conditions.
	
	
		Transfer the vial s contents plus 5 ml of complete medium (see below for recipe) to a 15 ml centrifuge tube. Use an additional 1 ml of medium to rinse the vial and transfer the liquid to the 15 ml tube. Add 4 ml of complete medium to bring the total volume to 10 ml.
	
	
		Gently mix and pellet the cells by centrifugation @ 270 xg for 5 minutes.
	
	
		Discard the supernatant and resuspend the cells with 10ml fresh growth medium (warm) and transfer to one T75 flask.
	
	
		Add 5 ml more fresh growth medium (warm) to flask.
	
	
		Incubate 37?C in a 5% CO2 in air atmosphere.
	
	
		Fluid change twice a week or when pH decreases. It is important to avoid excessive alkalinity of the medium during recovery of the cells. It is suggested that, prior to the addition of the vial contents, the culture vessel containing the growth medium be placed into the incubator for at least 15 minutes to allow the medium to reach its normal pH (7.0 to 7.6).
	
	
		Cells should be plated 24 hours before use as a feeder layer for ES cells and kept for no more than 7 days.
	
	
		Medium Renewal: Twice a week or when pH decreases
	
	
		Preservation: MEF (CF-1) IRR細胞Storage temperature: liquid nitrogen vapor phase
