However, cryopreservation with DMSO (the current gold standard) can result in poor cell function post-thaw and adverse reactions upon infusion. We hypothesize that non-DMSO cryopreservative molecules, including sugars, sugar alcohols, amino acids, and other small molecule additives.

Hello, The quick and dirty answer is: As the suspension of cells freezes, ice crystals form. These ice crystals can puncture the plasma membrane, leading to cell death. DMSO protects the cells by 1) partially solublizing the membrane so that it is less prone to puncture, and 2) interrupting the lattice of the ice, so that fewer crystals form.
Nov 13, 2012 · Other authors have discussed the potential for DMSO replacements, or at least compounds that can be used alongside DMSO to reduce its use in the critical environment of stem cell freezing. It summation while there are alternative cryoprotectants, none are truly capable of replacing DMSO as the gold standard.

Synth-a-Freeze Cryopreservation Medium is a chemically defined, protein-free, sterile cryopreservation medium containing 10% DMSO that is suitable for the cryopreservation of many stem and primary cell types with the exception of melanocytes.
Although DMSO protects cells from ice crystals, it’s also toxic. There are alternatives, such as glycerol and proprietary formulations developed by vendors. For example, Irvine Scientific makes a DMSO-free version of FreezIS. But Newman says so far, no alternative cryoprotectant works as well as DMSO.
A typical cryopreservation protocol involves the slow cooling of a sample in the presence of a cryoprotectant. DMSO, a penetrating cryoprotectant, is widely used. The exact mechanism by which DMSO protects cells remains a source of debate but it has been suggested that DMSO replaces water in the cell (Notman et al. 2006; Gurtovenko and Anwar 2007).

A general observation in the cryopreservation of cells and other biological systems is that each system has a specific optimal cooling rate, with decreased survival at cooling rates that are too low (slow-cooling damage) or too high (fast-cooling damage) (Mazur et al., 1972).
Cryo-preservation or cryo-conservation is a process where organelles, cells, tissues, extracellular matrix, organs, or any other biological constructs susceptible to damage caused by unregulated.
Cryopreservation with DMSO Freezing of HPC products requires the addition of a cryoprotective agent to prevent cell injury during low storage temperatures. DMSO is the most commonly used cryoprotectant for HPC products at concentrations up to 10% to reduce intracellular ice.
using dmso is as they explained before, using fcs is importent too for 2 reasons one of them is for dilluting the dmso (dmso can hurt the envelope of the cells thats why u freez the cell with 10% dmso and the rest is fcs or fbs- it doesnt matter)- so when u thaw the cells they will be ok

DMSO – Cryopreservation Comes With a Cost. November 11, 2011 • Written by Brandy Sargent. Dimethyl sulfoxide (DMSO) is frequently used in cell banking.
0 0 1 Total: 1 Dimethyl sulfoxide (DMSO) is frequently used in cell banking applications as a cryoprotectant. When added to media, DMSO prevents intracellular and extracellular crystals from forming in cells during the freezing process. Without a cryoprotectant, these crystals cause cell death, thus rendering the cells useless for transplant.

Cryopreservation and storage of frozen platelets may significantly prolong their shelf life. Thus, frozen platelets provide long-term accessibility in situations where fresh products are not available. The most widely used method for the platelets cryopreservation is freezing at 5–6% DMSO at −80°C.
complete medium containing 10% DMSO (dimethylsulfoxide) 50% cell-conditioned medium with 50% fresh medium with 10% glycerol or 10% DMSO; Cryopreservation media generally consist of a base medium, cryopreservative, and a protein source. The crypreservative and protein protect the cells from the stress of the freeze-thaw process.
