Preparation of BME-coated Plates
- Thaw Cultrex BME on ice at 2 °C to 8 °C overnight.
- Aliquot thawed Cultrex BME into pre-cooled tubes and store at -20° C.
- Thaw the aliquot on ice at 2 °C to 8 °C.
- Dilute Cultrex BME 1:40 in DMEM/F12. This can be stored at 4 °C for up to 2 weeks.
- Coat the desired number of plates with diluted Cultrex BME (approximately 2.5 mL/60 mm plate) and incubate for 1-2 hours at room temperature.
- Remove the Cultrex BME solution immediately prior to plating the cells.
I. Preparation and plating of BG01V Human Embryonic Stem Cells
Gently transfer thawed BG01V human embryonic stem cells to a 15 mL centrifuge tube containing pre-warmed MEF Conditioned Media.
Centrifuge at 200 x g for 4 minutes.

Resuspend the cell pellet in MEF Conditioned Media supplemented with 4 ng/mL FGF basic.

Add the BG01V human embryonic stem cells to the Cultrex BME- or StemXVivo-Culture Matrix-coated plates.

Culture the cells at 37 °C and 5% CO2 and change the media daily.

II. Passaging BG01V Human Embryonic Stem Cells
Coat plates with Cultrex BME or StemXVivo Culture Matrix as described.
Remove the media from cells and add 1 mL of Accutase solution to each 60 mm plate.
Pipette gently over the plate until all of the cells have detached.

Transfer the cell suspension to a 15 mL centrifuge tube containing < 5 mL of MEF Conditioned Media.
Centrifuge at 200 x g for 4 minutes.

Resuspend the cell pellet in MEF Conditioned Media.
Perform a cell count.

Plate the desired number of cells (approximately 1.0 x 106 cells/60 mm plate) on Culture BME- or StemXVivo Culture Matrix-coated plates in MEF Conditioned Media containing 4 ng/mL FGF basic.

Culture the cells at 37 °C and 5% CO2 and change the media daily.

Verified Customer | Posted 09/13/2019We used to make are own, however the quality would often vary. This commercial media enables us to standardise the protocol and we have used a number of lots with equal results. We usually use the media for 24 hours before starting a iPSC differentiation in order to 'prime' the cells. I would recommend for those who wish to increase the efficiency of iPSC differentiation.

FAQs for Mouse Embryonic Fibroblast (MEF) Conditioned Media

Have you tried the StemXVivo® Cardiomyocyte Differentiation Kit with other human ES cell lines or human iPS cell lines?
This kit has been tested both in-house and by outside groups in multiple iPS cell lines. This kit is expected to work with most cell lines as long as the starting stem cell population is of high quality and has pluripotency. For optimal performance using this kit, it is recommended that pluripotent stem cells are grown in Mouse Embryonic Fibroblast (MEF) Conditioned Media (Catalog # AR005), however successful differentiation has been observed in cells grown with mTeSR™ medium. We have had difficulties with cells grown in TeSR™-E8 media. An anti-human Cardiac Troponin T antibody is provided in the kit to help determine the efficiency of differentiation.
