While utilized, in numerous settings, the functionality of frozen PBMCs is often limited, and a disconnect exists between measured viability and outcome. In this study we investigated parameters affecting outcome including storage protocol, freeze media, and assessment assay. PBMCs were isolated from seven healthy donors and cryopreserved in: (1) a media-based cocktail (SAIC), (2) CryoStor 7.5 (CS7.5), and (3) CryoStor 7.5 plus caspase inhibitors (CS7.5 ± Inh). All samples were stored in vapor phase liquid nitrogen (static) with replicates exposed to a thermal cycling regime, which mimicked typical sample handling (cycle). Viability was assessed immediately postthaw by trypan blue.

These peptides, produced from the activity of one or more protease(s), by themselves may not reflect a disease-associated biomarker(s), but in fact, show the downstream effect of disease specific protease(s). The ability to select “true” biomarkers of disease is mired by the inter- and intrapatient variability typically observed in a proteomics approach to serum biomarker discovery. As an example, serum from an individual was collected with three types of serum separator tubes (SST) and stored at 4°C for prolonged periods of time. The postcollection integrity of the serum was examined using microcapillary nanoflow reversed-phase liquid chromatography (nano-RPLC) tandem mass spectrometry (MS/MS) of the trypsin-digested, low molecular weight protein fraction.

Although the term “preservation” is used by all these fields and refers to the maintenance of chemical and physical integrity of the DNA molecule, it should not be surprising that the perspectives of scientists from these distinct fields differ significantly. Most notably, the time frame for stability of a pharmaceutical product is approximately 2 years, whereas meaningful stability for an evolutionary biologist is measured in the hundreds of millions of years. Such divergent viewpoints not only have a significant effect on the time span of preservation, but also on what criteria are used to assess “stability.” This review discusses the literature addressing the maintenance of DNA integrity from the perspective of developing methods that offer improved preservation. Specifically, studies on the stability of DNA in solution, frozen, and dried are discussed.

Recent focus on delayed-onset cell death (DOCD) is providing an explanation for this observed failure. One potential avenue for the activation of DOCD involves the intrinsic mitochondrial-apoptotic pathway. Specifically, stressors can disrupt the pro-/anti-apoptotic protein balance associated with the mitochondria and the related Bcl-2 protein family. We hypothesized that CP-dependent disruption of the pro-/anti-apoptotic ratio (specifically, Bax: Bcl-XL) contributes to the activation and progression of DOCD. In this study, human dermal fibroblasts were cryopreserved in various freeze media (media +5% DMSO or CryoStor™ CS5), frozen at 1°C · min−1to −80°C and stored in LN2. Following storage, cells were rapidly thawed and plated in culture media. Viability was assessed daily using a metabolic indicator (alamarBlue) and a nucleic acid probe (SytoDye).

The cell volume change was also measured after the cells were exposed and equilibrated to different anisosmotic conditions. It was found that the cell volume was a linear function of the reciprocal of the extracellular osmolality (Boyle–van't Hoff plot).

Very little is known about the extent of oxidative damage that occurs during the desiccation of mammalian cells. The objective of this study was to modify and validate a method for the determination of lipid peroxidation in desiccated red blood cells (RBCs). The measurement of malondialdehydes (MDAs), the decomposition products of oxidized polyunsaturated fatty acids, is commonly used as a method for the quantification of lipid peroxidation. The method is based on the reaction of MDAs with thiobarbituric acid, which forms a thiobarbituric acid reactive substances (TBARS) chromophore. Validation of the method to dried RBC specimens included the optimization of an MDA standard curve, spiking studies, measurement of TBARS in lyophilized RBCs, and reexamination of the reagents and processes that are associated with this assay.

Animals were sacrificed at either 2 or 4 weeks after implantation, and the vein grafts were harvested for study.

Cryotherapy utilizes reversible moderate ultra-hypothermic temperatures to transiently halt electrophysiological activity to identify target areas for ablation with minimal damage to the nonarrhythmogenic tissue. This represents a potential advantage over heat-based therapies. Subsequent application of subfreezing temperatures to the targeted cells results in cellular ablation and ultimately correction of the arrhythmia. An in vitro study was performed to characterize and investigate the efficacy of cryotherapy procedures in mammalian cardiac systems. Mammalian cardiomyocytes were isolated from neonatal rats and seeded in tissue culture plates.
