Controlled Freezing and Open-Pulled Straw (OPS) Vitrification of In vitro Produced Bovine Blastocysts Following Analysis of ATP Content and Reactive Oxygen Species (ROS) Level

Journal of Integrative Agriculture, 2012
To our knowledge, no single study has systemically compared cryopreservation efficiencies of bovine blastocysts derived from in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI) and somatic cell nuclear transfer (SCNT) by controlled ...

Vitrification of Heart Valve Tissues

, 2014
Application of the original vitrification protocol used for pieces of heart valves to intact heart valves has evolved over time. Ice-free cryopreservation by Protocol 1 using VS55 is limited to small samples where relatively rapid cooling and warming rates are possible.

Factors affecting the incidence of vitrification of in vitro propagated fruit trees

, 1996
In vitro Clonal propagation of fruit trees to produce large number of plants, often leads with the problem of vitrification or hyperhydric transformation. This physiological disorder was observed in pear, quince, grape and date palm.

Use of Eco-friendly recipients for vitrification of Hyphessobrycon boulengery Spermatogonial cells [PDF]

Anais da Academia Brasileira de Ciências
The aim of the study was to evaluate the efficiency of the gelatin and Hypromellose capsules as recipients to vitrification of lambari spermatogonial cells. In experiment 1, four protocols to vitrification (P1, P2, P3 and P4) were tested. The protocol P3

Homologous membrane wrapped ZIF‐8 nanoparticles accelerate differentiation of neural stem cell for spinal cord injury therapy

BMEMat, EarlyView.
Homologous membrane wrapped ZIF‐8 nanoparticles were proposed to improve biocompatibility and targeting ability to neural stem cells (NSCs). ZIF‐8‐SCM NPs exhibit pH responsiveness, thereby generating an intracellular Zn2+ storm to accelerate neural differentiation through calcium and MAPK signaling pathways. Moreover, they promote function recovery in
