Effect of Platelet Rich Plasma on Post Cryopreservation Viability, Morphology and Proliferation of Human Umbilical Cord Stem Cells [PDF]

open access: yes, 2015
: In most cryopreservation medium, Fetal Bovine Serum (FBS) is used as supplement, while it is well known that FBS contains xenoproteins that can be incorporated into the cells and may be harmfull, as they can elicit immune response.

Myo‐Inositol Mitigates Oxidative Stress in Bovine Mammary Epithelial Cells via Activation of the SIRT5/Nrf2 Signaling Axis

open access: yesAnimal Research and One Health, EarlyView.
Myo‐inositol alleviates oxidative stress in dairy cow mammary epithelial cells via the Sirt5/Nrf2 pathway to promote mitochondrial fusion. This graphical abstract was created with BioRender.com. ABSTRACT High‐yielding dairy cows are susceptible to mammary gland oxidative stress due to prolonged intensive lactation, leading to redox imbalance.

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

open access: yesAnimal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

Development of Islet Cryopreservation for Type 1 Diabetes Cell Therapy

open access: yesZhileng xuebao, 2021
In recent years, cell therapy technology for type 1 diabetes has advanced rapidly, but the lack of donor pancreatic islets and the time and space mismatch between donor and recipient limits its clinical application. Cryopreservation technology provides a

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Bottom‐Up Ice Growth Geometry Attenuates Shear Stress and Improves the Cryopreservation of Hematopoietic Stem/Progenitor Cells Under Low DMSO Concentrations

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Studies on cell cryopreservation have been limited by the complexity of the freezing process and challenges on controlling ice formation, managing cooling rates, and optimizing cryoprotectant concentrations. The objective of this study is to evaluate the impact of bottom‐up and conventional radial freezing on the viability of mammalian cells ...
