INQUIRY
1 vial
J1 is an embryonic stem cell that was isolated from the inner cell mass of a mouse. This cell can be used as a biomarker: Included in microarray studies aimed at developing methods for detecting novel marker ES genes, as well as biomarker signature patterns expressed during differentiation. The cell can be used in embryonic development and cancer research.

| Handling procedure | Complete Medium for Feeder Cells Feeder cells may be grown in medium containing fewer growth factors than those required by the ES cells. Consult the product sheet provided for the feeder cells you wish to use for medium requirements. Feeder cells should be initiated 24-48 hours prior to inoculating with embryonic stem (ES) cells. Feeder Cells recommends culturing J1 on mouse embryonic fibroblasts (MEFs) that have been mitotically arrested by either irradiation or treatment with Mitomycin-C. J1 cells have been cultured on mitotically arrested MEF (CF-1) . At least one day before plating the ES cells, prepare the desired combination of flasks with feeder cells to accommodate an initial ES cell seeding density of 30,000 cells/cm2 to 50,000 cells/cm2. Refer to the batch specific information provided on the last page of the product information sheet for the total number of viable cells recovered from this product. Plate mitotically arrested mouse embryonic fibroblasts (MEFs) as a feeder layer at approximately 55,000 feeder cells/cm2 in complete medium for feeder cells. Refer to the product sheet for mitotically arrested MEF for detailed handling instructions. Feeder cells should be used within one week of plating. It is best to use feeder cells within 24-48 hours of initiation. Embryonic Stem (ES) Cells 30 Minutes Prior to Handling Cells – Pre-warm complete growth medium for ES cells at 37°C for at least 30 minutes before adding to cells. One Hour Prior to Thawing the ES Cells – Perform a 100% medium change for the MEFs using complete growth medium for ES cells. Thaw the vial of ES cells 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. Thawing should be rapid (approximately 90 seconds). Remove the vial from the water bath before the contents are completely thawed, and decontaminate by dipping in or spraying with 70% ethanol. 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 growth medium for ES cells to a 15 mL centrifuge tube. Use an additional 1 mL of media to rinse the vial and transfer the liquid to the 15 mL tube. Add 4 ml of complete growth medium for ES cells to bring the total volume to 10 mL. Spin the cells at 270 x g for 5 min. Aspirate the supernatant and resuspend the pellet in 2 mL of complete growth medium for ES cells. Add the 2 mL of cell suspension to the appropriate size flask containing feeder cells and fresh compelte growth medium for ES cells (see batch specific information). ES cells should be plated at a density of 30,000 – 50,000 cells/cm2. Incubate the culture at 37°C in a humidified 5% CO2/95% air incubator. Routine Handling Perform a 100% medium change every day. Passage 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. Make sure that you have prepared a sufficient number of flasks pre-plated with MEF feeder layers to support frequent passage of the ES cells. |
