CellMatrix Basement Membrane Gel


Volume: 5 mL
Storage: -80°C

CellMatrix Basement Membrane Gel is a soluble, growth factor reduced basement membrane extract that does not contain phenol red. CellMatrix Gel is purified from murine Engelbreth-Holm-Swarm (EHS) tumor. Major components include laminin, collagen IV, entactin and heparin sulfate proteoglycan.

Product category
Each lot of CellMatrix Gel is shown to promote the attachment of hESCs/hiPSCs and to maintain hESCs/hiPSCs in a pluripotent state as determined by the expression of Oct-4 and Nanog pluripotent markers.
Store at -80°C in aliquots. Avoid repeated freezing and thawing.

Biosafety Icon BSL 1

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

Handling information

Handling procedure

Preparation and storage

Critical: CellMatrix Membrane Gel must remain frozen at all times during storage. Once thawed, keep CellMatrix on ice at all times. Do not allow it to warm above 4°C or premature gelation will occur.


  1. Thaw stock CellMatrix Membrane Gel vial on ice in a 4°C refrigerator overnight.
  2. Determine the appropriate volume per aliquot based on concentration and application. Please refer to the certificate of analysis for the lot­specific concentration.
  3. Dispense appropriately­sized aliquots using pre­cooled tips into pre­cooled tubes on ice and re-freeze immediately.
  4. Thaw aliquots on ice. Once thawed, do not re-freeze. Once thawed, use within 7 days.
A. Three-dimensional culture of organoids in CellMatrix
  1. Thaw an aliquot of CellMatrix on ice and keep on ice.
  2. Resuspend dissociated organoids (fragments or single cells) in undiluted CellMatrix. Do introduce bubbles when pipetting. Work quickly to ensure the suspension remains cold.
  3. Dispense as small droplets in a pre-warmed (in a 37°C cell culture incubator) tissue culture treated vessel (e.g., 50 µL per well in a 24-well plate). Work quickly to prevent premature gelation.
  4. Place the plate in a 37°C cell culture incubator for 15-30 minutes to induce gelation.
  5. Add an appropriate volume of organoid culture media.

Harvesting organoids from CellMatrix

  1. Aspirate the media from the well completely
  2. Using a cell lifter scrape the well surface to release the gelled domes
  3. Transfer the domes to a 15 conical tube.
  4. Pipet up and down 20-30 times to break up the domes and release the organoids from the CellMatrix gel.
  5. Wash the organoids in cold DMEM:F12 (ATCC 30-2006) by centrifugation.
  6. Aspirate the supernatant leaving behind the pellet of organoids.
  7. Proceed with downstream assays using the organoids or resuspend in fresh CellMatrix to continue culture.
B. Sandwich culture of human hepatocytes
  1. Thaw hepatocytes and seed on collagen type-1 coated plates.
  2. After 6-24 hours, perform a complete media change with cold hepatocyte maintenance media that has been supplemented with 0.25 mg/mL CellMatrix. Refer to the certificate of analysis for the lot­specific concentration. For example, if the lot-specific concentration of CellMatrix is 15 mg/mL, add 16 uL CellMatrix per mL of hepatocyte culture media.
  3. Return plate to the incubator.
  4. After 24 hours perform a complete media change with hepatocyte maintenance media (not supplemented with CellMatrix).
C. Angiogenesis modeling via the tube formation assay
  1. Thaw CellMatrix Gel in the refrigerator (2°C to 8°C), in ice, overnight.
  2. Mix well by carefully pipetting CellMatrix Gel up and down, being careful not to introduce air bubbles.
  3. Do not dilute. Pipette 150 µL/cm2 onto the tissue culture vessel surface.  
  4. Swirl the vessel gently to ensure that the entire surface is evenly covered.
  5. Leave the coated dishes at 37°C for 30 minutes.
  6. The coated vessels are ready for use. 

D. Feeder-free culture of human embryonic stem cells (hESC) and induced pluripotent stem cells (hiPSC)

Refer to the ATCC Stem Cell Culture Guide for more information.

Important: CellMatrix Gel will solidify in 15 to 30 minutes if the temperature is above 15°C. Keep CellMatrix Gel and labware (pipette tips, serological pipettes, conical tubes) on ice at all times to prevent the matrix from gelling prematurely. If air bubbles form when coating the dishes, use a chilled pipette tip to break up the bubbles.

For stem cells, NPCs, NPCs-derived neurons:

  1. Thaw CellMatrix Gel in the refrigerator (2°C to 8°C), in ice, overnight.
  2. Dilute the thawed CellMatrix Gel to 150 µg/mL by directly adding CellMatrix in cold DMEM: F­12 Medium (ATCC 30­-2006) on ice and mix well. Immediately coat each 6 cm dish with 2 mL diluted CellMatrix Gel.
  3. Swirl dish gently to ensure that the entire dish is evenly covered.
  4. Leave the coated dishes at 37°C for one hour.
  5. Aspirate the coating solution and immediately plate the cells. It is critical that the coating does not dry out.
  6. If the dishes will not be used the same day they are prepared, do not aspirate the coating solution. Seal the coated dishes with parafilm and store at 2°C to 8°C for up to one week. Note that stored dishes should be warmed to room temperature in a biological safety cabinet for at least one hour before use.
