Take a look at our Thought Leadership Q&A with Dr. Jelte van der Vaart discussing how to simplify and standardize your organoids cryopreservation, and the importance of GMP-approved cryopreservation for regenerative medicine applications!

CELLBANKER Freezing Media Series

As a cell freezing medium, CELLBANKER® does not require a gradual temperature decrease in a programmed freezer or storage in liquid nitrogen to guarantee efficient cell storage. This makes CELLBANKER® more affordable and accessible than other cell freezing media. CELLBANKER® solutions are simple to use and allow you to achieve the highest cell viability while maintaining your organoids function.

  • Ready-to-use serum-containing cell cryopreservation medium
  • Suitable for a range of mammalian cell cultured, organoids, & tissues
  • High viability after freeze-thaw cycles, even for sensitive cells


  • Chemically defined, animal-free, GMP-compliant stem cell cryopreservation solution, for basic research and in the clinical application of cell therapy
  • Manufactured in compliance with JPN, EU, US and PIC/S GMP guidelines.
  • Validated for cryopreservation of organoids and tissues with high viability.
  • Optimized for stem cells and iPS cells storage.
  • Available in DMSO-containing and DMSO-free formulations.


  • Ready-to-use serum-free cell cryopreservation medium.
  • Optimized for serum-free cultured cells and peptide/protein expressing cells.
  • No risk of contamination from serum.


  • Chemically defined, xeno-free, GMP-compliant cryopreservation media.
  • Suitable for cell, organoid, and tissue cryopreservation.
  • All components are approved for intravenous application, streamlining your
    clinical translation.
  • Optimized for applications in regenerative medicine: no requirement for
    washing of the cryopreservation solution upon delivery of the cell therapy
Drug Master Files have been registered with the FDA for both STEM-CELLBANKER® and STEM-CELLBANKER® EX, for streamlined clinical translation!

Human Airway Organoids Cryopreserved in CELLBANKER® 1

Dr. Jelte van der Vaart, whilst a PhD student in the world famous Clevers lab*, utilized CELLBANKER® 1 to simply and safely cryopreserve his organoids as we were entering the first COVID-19 lockdown. They found that the procedure was "a lot easier and faster since they could simply transfer the organoids in CELLBANKER to the freezer immediately".

The presence of KRT5+ cells shows that the lung airway organoids are still consistent of stem cells which can be propagated into more organoids, in short the culture is still able to expand. This is an important message as well for the thawing that basal cells survive the freezing.

Human Bronchial Organoids Cryopreserved in STEM-CELLBANKER®

STEM-CELLBANKER® is GMP compliant, for applications of organoids in regenerative medicine, disease modelling and drug discovery. For example, Dr. Kazuo Takayama at the Center for iPS Cell Research and Application (CiRA) in Japan used STEM-CELLBANKER® to cryopreserve human bronchial organoids, as shown in Fig. 2 below.

“STEM-CELLBANKER® is an essential resource for freezing our bronchial organoids.

Motor Neurons Cryopreserved in STEM-CELLBANKER®

Chia-Yu Chang, et al. developed a robust protocol to convert hPSCs into Motor neurons (MN). Near-mature MNs were cryopreserved in STEM-CELLBANKER GMP grade and had a high thawing survival rate and 89% MN marker expression on day 32.
