Vitrification of In vitro-matured Oocytes: Effects of meiotic spindle morphology on clinical outcome

Reproductive and Developmental Medicine, 2020
Objective: The meiotic spindle controls chromosome movement and mediates various functions essential for fertilization and early postfertilization events. This study aimed to examine whether vitrification causes meiotic damage in vitro- matured metaphase

Molecular design of polyampholytes for vitrification-induced preservation of three-dimensional cell constructs without using liquid nitrogen.

Biomacromolecules, 2020
Current slow-freezing methods are too inefficient for cryopreservation of three-dimensional (3D) tissue constructs. Additionally, conventional vitrification methods use liquid nitrogen, which is inconvenient and increases the chance of cross ...

The Anisotropic Adsorption of De Novo Allosteric Two‐Component Protein Fibers on Mica Surfaces

Advanced Functional Materials, EarlyView.
In this study, the interfacial behavior of de novo designed proteins that self‐assemble into tubular architectures with distinct morphologies — small (S), large (L), and helical (H) fibers — at the muscovite mica‐water interface is explored using in situ AFM. Abstract Protein adsorption at solid–liquid interfaces underlies many biomedical and materials

Research Progresses in Vitrification by Minimum Volume Method

Zhileng xuebao, 2018
Vitrification is an effective method in the field of cryopreservation since it can prevent the formation of ice crystals. Vitrification requires ultra-fast cooling rates and high concentrations of cryoprotective agents.

Controlling Intestinal Organoid Polarity using Synthetic Dynamic Hydrogels Decorated with Laminin‐Derived IKVAV Peptides

Advanced Healthcare Materials, EarlyView.
Design rules are presented to control intestinal organoid polarity in fully synthetic hydrogels. The laminin‐derived IKVAV sequence is crucial to obtain correct intestinal organoid polarity. Increasing hydrogel dynamics further supports the growth of correctly polarized intestinal organoids, while a bulk level of stiffness (G’ ≈ 0.7 kPa) is crucial to ...

Innovative multi-protectoral approach increases survival rate after vitrification of ovarian tissue and isolated follicles with improved results in comparison with conventional method

Journal of Ovarian Research, 2018
Background In recent years, autotransplantation of cryopreserved ovarian tissue became a promising approach to preserve female fertility. The slow freezing is the most effective technique which resulted in greater live birth incidence so far.

Fertility preservation in pig using ovarian tissues by vitrification method

Journal of Animal Reproduction and Biotechnology, 2022
Cryopreservation of porcine ovarian tissue by vitrification method is a promising approach to preserve genetic materials for future use. However, information is not enough and technology still remains in a challenge stage in pig. Therefore, the objective

Cryopreservation of Byrsonima intermedia embryos followed by room temperature thawing [PDF]

, 2015
Byrsonima intermedia is a shrub from the Brazilian Cerrado with medicinal properties. The storage of biological material at ultra-low temperatures (-196°C) is termed cryopreservation and represents a promising technique for preserving plant diversity ...

Triazine‐Trione Thermosets with High Processability for Scaffold Applications in Bone Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Novel photo‐clickable triazine‐trione thermosets can be shaped and cured under mild conditions, including room and physiological temperatures. These materials are biocompatible and support osteogenic differentiation of bone marrow–derived mesenchymal stem cells on their surface.
