Parthenogenetic activation of mammalian oocytes with artificial stimuli is commonly applied in various reproductive biotechniques, e.g. cloning using nuclear transfer. For this reason, many studies fo...
Porcine oocytes matured in vitro were activated for parthenogenetic development using either calcium ionophore (50μM for 10 min) or nitric oxide donor SNAP (2mM for 23.5 hours). Protein kinase C (PKC)...
Social groups balance flexibility and robustness in their collective response to environmental changes using feedback between behavioural processes that operate at different timescales. Here we...
The intracytoplasmic sperm injection (ICSI) procedure has recently been utilized to produce transgenic animals and may serve as an alternative to the conventional pronuclear microinjection in species ...
These experiments were carried out to optimize the parameters of electrical activation, methods of parthenogenetic activation and embryo culture in vitro and meanwhile to isolate embryonic stem cells-...
This study was conducted to improve efficiency of a follicle culture system without reducing developmental competence of intrafollicular oocytes. Preantral follicles (100 to 125 m in diameter)...
Considerable attention has been focused on the cloning of mammalian embryos, as a consequence of poor development, in order to enhance the application of genetic engineering. Experiments were conducte...
