Applications: ATCC SCRC-1040.2 or ATCC SCRC-1040.1) exhibit uniform morphology, a predictable growth rate, and are easy to maintain in culture.

BG01V cells are pluripotent and can differentiate to representatives of the three primary germ layers.

BG01V was derived from the wild-type, parental hESC line BG01 [PMID 12968106, PMID 15153607].

The cells stain positive for pluripotency markers and alkaline phosphatase activity.

Cytogenetic Analysis: 49, XXY, +12, +17

Age: embryo, blastocyst

Comments: hESC BG01V細胞BG01V is a human embryonic stem cell line with an abnormal karyotype. BG01V was derived from the wild-type, parental hESC line BG01 [PMID 12968106, PMID 15153607]. Despite the abnormal karyotype, BG01V cell colonies grown on irradiated or Mitomycin C-treated Mouse embrynic fibroblast (MEFs - e.g. ATCC SCRC-1040.2 or ATCC SCRC-1040.1) exhibit uniform morphology, a predictable growth rate, and are easy to maintain in culture. BG01V cells are pluripotent and can differentiate to representatives of the three primary germ layers. The cells stain positive for pluripotency markers and alkaline phosphatase activity.

Propagation: ATCC complete growth medium: 1:1 Mixture of Dulbecco's Modified Eagles Medium and Ham's F-12 medium containing 1.2 g/L sodium bicarbonate, 2.5 mM L-glutamine, 15 mM HEPES and 0.5 mM sodium pyruvate (ATCC 30-2006) supplemented with 2.0 mM L-Alanyl-L-Glutamine (ATCC 30-2115), 0.1 mM Non-essential amino acids (ATCC 30-2116), 0.1 mM 2-mercaptoethanol (Sigma Catalog No. M-7522) and 4 ng/ml bFGF (R& D Systems Catalog No. 233-FB), 80%; Knockout serum replacement (Invitrogen Catalog No. 10828), 5%; fetal bovine serum (ATCC SCRR-30-2020), 15%

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

Temperature: 37.0°C

Subculturing: Protocol: To insure the highest level of viability, be sure to warm media to 37C before using it on the cells. The passaging ratio depends on the density/confluency of the colonies. It ranges between 1:3 and 1:6. Note: If the colonies are close to or touching each other the culture is overgrown (refer to images on the SCC website - stemcells.atcc.org). Overgrowth will result in differentiation.

1. At least 24 hours prior to each passage, plate treated MEFs onto the culture vessels to be used. Base the number of dishs/flasks to be used on the passaging ratio hESC BG01V細胞(see product sheet).

2. Prepare 0.5 mg/ml or approximately 200 units/ml Collagenase IV solution (Invitrogen 17104-019) in DMEM/F12 and sterile filter using 0.22 micrometer low-protein binding filter. Check the units/mg for each lot of powder.

3. Remove medium from cells. Add appropriate volume (see product sheet) of Collagenase IV solution.

4. Incubate at 37C for up to 2 hours.

5. Check the cells after the first 30 minutes and then every 15 minutes. When the majority of the hESC colonies have completely detached or the edges of the colonies have rounded up, add appropriate amount (see product sheet) of DMEM/F12 and wash gently using a pipette. Under optimal conditions, all the colonies can be washed off with feeder cells left behind. If some colonies are still attached, gently scrape the surface area with the tip of a 5 ml pipette if necessary.

6. Collect cell suspensions into a 50 ml conical tube.

7. Centrifuge for 5 minutes at 200 x g at 25C.

8. Remove the supernatant and resuspend in complete growth medium. Pipette up and down to break the colonies to smaller clumps and evenly distribute cells to feeder-covered dishes/flasks.

9. Add complete growth medium to each tissue culture vessel to achieve the appropriate final volume. Please consult the product sheet for details.

Medium Renewal: Every day after the first 48 hours

Preservation: Freeze medium: culture medium, 70%; fetal bovine serum, 20%; DMSO, 10%

Storage temperature: liquid nitrogen vapor phase
