Can we use less DMSO?

Define better first

Reducing exposure to DMSO may address some toxicity concerns, but an alternative must also provide enough protection during cooling and warming. The useful comparison is biological performance across the full process.

Avoid transferring claims too far

Results in one cell type are indirect evidence for another. A convincing study needs matched controls, a clearly reported formulation, appropriate time points, and functional endpoints. No universal DMSO-free recipe is claimed here.

Read with these questions in mind

• What biological material was studied?
• What comparison group and recovery measurements were used?
• What would need to be tested before applying this elsewhere?
