Abstract
Cryopreservation of red blood cells (RBCs) is imperative for transfusion therapy, while cryoprotectants are essential to protect RBCs from cryoinjury under freezing temperatures. Trehalose has been considered as a biocompatible cryoprotectant that naturally accumulates in organisms to tolerate anhydrobiosis and cryobiosis. Herein, we report a feasible protocol that enables glycerol-free cryopreservation of human RBCs by integration of the synthesized trehalose lipids and dissociative trehalose through ice tuning and membrane stabilization. Typically, in comparison with sucrose monolaurate or trehalose only, trehalose monolaurate was able to protect cell membranes against freeze stress, achieving 96.9 ± 2.0% cryosurvival after incubation and cryopreservation of human RBCs with 0.8 M trehalose. Moreover, there were slight changes in cell morphology and cell functions. It was further confirmed by isothermal titration calorimetry and osmotic fragility tests that the moderate membrane-binding activity of trehalose lipids exerted cell stabilization for high cryosurvival. The aforementioned study is likely to provide an alternative way for glycerol-free cryopreservation of human RBCs and other types of cells.

Abstract
Currently, glycerol is a conventional cryoprotectant of human red blood cells (hRBCs), but the time-consuming thawing and deglycerolization processes are essential before transfusion. Much of the research up to now has been conducted on the delivery of impermeable trehalose to hRBCs at 37 °C, but the cryoprotective effect of trehalose and deterioration of cells still remain challenging. Encouraged by the interaction of hydrophobic or cationic groups on cell membranes and osmotic stabilization, herein, we propose a novel cryopreservation system to facilitate trehalose entry into hRBCs at 4 °C and pH 7.4. High intracellular trehalose contents and cryosurvival of hRBCs were achieved with small function variations via the assistance of self-assembled nanoparticles of alkylated ε-poly(L-lysine) (ε-PL) along with poly(vinyl pyrrolidone) (PVP). The effect of amphipathic alkylated ε-PL with various alkyl chains and grafting ratios on membrane perturbation with protection of PVP was systematically investigated. Overall, by the combination of alkylated ε-PL and PVP, the intracellular trehalose could be enhanced to 109.7 ± 6.1 mM and subsequently hRBC cryosurvival reached 91.7 ± 5.5%, significantly higher than those containing trehalose only, 11.9 ± 1.1 mM and 50.0 ± 2.1%, respectively. It was observed that the biocompatible trehalose-loading system could benefit glycerol-free cryopreservation of hRBCs and also provide a feasible way for impermeable biomacromolecule delivery.

Abstract
Ice formation and recrystallization exert severe impairments to cellular cryopreservation. In light of cell-damaging washing procedures in the current glycerol approach, many researches have been devoted to the development of biocompatible cryoprotectants for optimal bioprotection of human erythrocytes. Herein, we develop a novel ACTIVE glycopeptide of saccharide-grafted ε-poly(L-lysine), that can be credited with adsorption on membrane surfaces, cryopreservation with trehalose, and icephilicity for validity of human erythrocytes. Then, by Borch reductive amination or amidation, glucose, lactose, maltose, maltotriose, or trehalose was tethered to ε-polylysine. The synthesized ACTIVE glycopeptides with intrinsic icephilicity could localize on the membrane surface of human erythrocytes and improve cryopreservation with trehalose, so that remarkable post-thaw cryosurvival of human erythrocytes was achieved with a slight variation in cell morphology and functions. Human erythrocytes (∼50% hematocrit) in cryostores could maintain high cryosurvival above 74%, even after plunged in liquid nitrogen for 6 months. Analyses of differential scanning calorimetry, Raman spectroscopy, and dynamic ice shaping suggested that this cryopreservation protocol combined with the ACTIVE glycopeptide and trehalose could enhance the hydrogen bond network in nonfrozen solutions, resulting in inhibition of recrystallization and growth of ice. Therefore, the ACTIVE glycopeptide can be applied as a trehalose-associated "chaperone", providing a new way to serve as a candidate in glycerol-free human erythrocyte cryopreservation.

Abstract
![]()
From trauma wards
to chemotherapy, red blood cells are essential
in modern medicine. Current methods to bank red blood cells typically
use glycerol (40 wt %) as a cryoprotective agent. Although highly
effective, the deglycerolization process, post-thaw, is time-consuming
and results in some loss of red blood cells during the washing procedures.
Here, we demonstrate that a polyampholyte, a macromolecular cryoprotectant,
synergistically enhances ovine red blood cell cryopreservation in
a mixed cryoprotectant system. Screening of DMSO and trehalose mixtures
identified optimized conditions, where cytotoxicity was minimized
but cryoprotective benefit maximized. Supplementation with polyampholyte
allowed 97% post-thaw recovery (3% hemolysis), even under extremely
challenging slow-freezing and -thawing conditions. Post-thaw washing
of the cryoprotectants was tolerated by the cells, which is crucial
for any application, and the optimized mixture could be applied directly
to cells, causing no hemolysis after 1 h of exposure. The procedure
was also scaled to use blood bags, showing utility on a scale relevant
for application. Flow cytometry and adenosine triphosphate assays
confirmed the integrity of the blood cells post-thaw. Microscopy confirmed
intact red blood cells were recovered but with some shrinkage, suggesting
that optimization of post-thaw washing could further improve this
method. These results show that macromolecular cryoprotectants can
provide synergistic benefit, alongside small molecule cryoprotectants,
for the storage of essential cell types, as well as potential practical
benefits in terms of processing/handling.

Abstract
BACKGROUND Yta is a high frequency red blood cell (RBC) antigen, present in 99.7% of studied populations. It is extremely immunogenic, and when anti-Yta is present, provision of Yt(a-) blood is often challenging. The objectives of our study were to assess the incidence and severity of acute hemolytic transfusion reactions to Yt(a+) donor RBCs in recipients with preformed anti-Yta and to identify any patient factors associated with severe hemolytic reactions. STUDY DESIGN AND METHODS Patients with anti-Yta identified by the Red Cell Reference Laboratories of the Australian Red Cross Lifeblood over the past 20 years were included. Their transfusion records were collected via the referring laboratory to ascertain if any patients received RBC transfusion and if there was any evidence of transfusion reactions. RESULTS Fifty-two patients with anti-Yta were identified; only 12 were confirmed to have received a RBC transfusion. Nine received Yt(a+) or untyped allogeneic RBCs, including four patients who received a total of 16 indirect antiglobulin test (IAT) crossmatch incompatible, likely Yt(a+) RBCs. None of the nine patients had documented acute hemolytic reactions. CONCLUSION There are limited published data describing the clinical significance of anti-Yta . Based on our data, it appears that transfusing patients with anti-Yta using incompatible crossmatched RBCs does not pose a significant risk of an acute hemolytic transfusion reaction when the antibody reaction strength is weak ≤2+ (0-4) by IAT crossmatch. For strong examples of the antibody, in the absence of other assay data, such as the monocyte monolayer assay, Yt(a-) blood should continue to be sourced where possible.
