Cryopreservation plays a crucial role in cell biology research, bioprocessing, and biomanufacturing. Traditionally, DMSO (dimethyl sulfoxide) has been the cryoprotectant of choice for preserving cells. However, DMSO’s toxicity, especially for sensitive cell types, is pushing the field toward safer, more effective alternatives—DMSO-free cryosolutions. These innovations are changing the landscape of cell preservation, not just for stem cell and CAR-T cell therapies, but for a wide range of applications from basic research to drug discovery.
The promise of DMSO-free solutions in research and industry
While DMSO’s ability to prevent ice formation during freezing has made it the gold standard, its toxicity to cells can limit its use, especially for more delicate cell types. This is where DMSO-free cryosolutions step in, offering benefits that extend far beyond clinical settings. These alternatives are proving to be highly effective for preserving cell viability and functionality, while also simplifying workflows. DMSO-free solutions reduce the need for multiple post-thaw washing steps, saving time in high-throughput settings and improving reproducibility in research.
The benefits extend to a variety of disciplines, including drug discovery, toxicity testing, neuroscience research, and high-throughput screening. Studies have shown that DMSO-free cryomedia improve post-thaw viability and functionality, making them more reliable than traditional methods in many contexts. However, despite these advantages, challenges remain. Cost, accessibility, and regulatory hurdles have slowed their widespread adoption. Table 1 summarizes the difference between DMSO-free cryomedia and DMSO-based media.

Overcoming barriers to widespread adoption
One of the main obstacles to adopting DMSO-free cryopreservation media is cost. These solutions are typically more expensive to produce because they rely on specialized cryoprotectants. For labs with limited budgets or those accustomed to using inexpensive DMSO, this can be a significant challenge. Availability is another issue—DMSO-free formulations are not as widely distributed or standardized as their DMSO counterparts, which have been long established in the field. Furthermore, regulatory approval remains a key concern. While DMSO is FDA-approved for certain clinical applications, DMSO-free cryomedia are still under evaluation for broader use, particularly in clinical settings.
To address these barriers, key actions must be taken:
- Investment in Research & Development: Further funding is needed to optimize and validate these formulations for diverse cell types and applications.
- Scaling Production: Manufacturers need to focus on cost-effective production methods to make DMSO-free cryomedia more affordable and accessible.
- Educational Outreach: Raising awareness about the benefits and versatility of DMSO-free cryomedia can help overcome skepticism.
- Cross-Sector Collaboration: Academia, industry, and regulatory bodies should work together to streamline approval processes and standardize DMSO-free formulations.
- Pilot Programs: Offering subsidized trials could incentivize labs to adopt these solutions and demonstrate their effectiveness.
Enhancing compatibility with automation
With the increasing trend toward automating lab workflows, DMSO-free cryosolutions are well-suited to modern cryopreservation systems. These solutions simplify the handling process, reducing human error and enhancing reproducibility. As automation in cell biology labs becomes more prevalent, DMSO-free solutions can help labs integrate more seamlessly into automated cryostorage and recovery systems, improving efficiency and accuracy.
The future of cryopreservation: a shift toward customization and safety
Looking ahead, DMSO-free cryomedia are set to become a cornerstone of next-generation cryopreservation. New research is exploring alternative cryoprotectants that can match or exceed DMSO’s performance while being less toxic to cells. Glycerol-based formulations, ethylene glycol, and proprietary solutions are all being investigated as potential alternatives to DMSO, offering safer cryopreservation methods without compromising cell integrity.
Additionally, as the demand for personalized medicine and cell therapies grows, there will be a greater need for specialized cryopreservation media. These formulations will be tailored to specific cell types, ensuring better preservation and post-thaw functionality. From stem cells to immune cells, the future of cryopreservation is shifting toward custom, application-specific solutions that minimize damage during freezing and thawing.
Finally, regulatory pathways are evolving. While DMSO has already been approved for clinical use, DMSO-free alternatives are undergoing rigorous testing to meet safety and efficacy standards. Collaborative efforts between industry and regulatory bodies will be key to speeding up the approval process, making these solutions accessible for clinical and therapeutic applications.
