This study was conducted to evaluate the effect of plant growth regulators on in vitro shoot multiplication, vitrification and rooting of two carnation cultivars (Eskimo Mogr and Innove Orange Bogr). Isolated axillary buds were cultured on MS medium supplemented with different levels of Benzyl amino purine (BAP) or kinetin (Kin) in combination with 0.2 mg/l NAA and shoot multiplication and vitr...

In the past decade, assisted reproductive technologies (ART) such as oocyte transfer, intracytoplasmic sperm injection (ICSI), and nuclear transfer (cloning) have become effective enough for clinical use. ART such as oocyte transfer and ICSI allow production of foals from mares that cannot provide an embryo by standard embryo-transfer procedures. For the equine practitioner, application of ART ...

background: the objective of this study was to investigate the effect of vitrification and in vitro maturation on the mitochondrial distribution and atp content of oocytes. methods: the oocytes at germinal vesicle (gv) and metaphase ii (mii) stages were recovered from 6-8 week old nmri strain female mice. the oocytes were divided into vitrified and non-vitrified groups. vitrification was done b...

Vitrification is a powerful tool for the efficient production of offspring derived from cryopreserved oocytes or embryos in mammalian species including domestic animals. Genome editing technologies such as transcription activator-like effector nucleases (TALENs) and clustered regularly interspaced short palindromic repeats (CRISPR)/ CRISPR-associated (Cas)9 are now available even for domestic s...

Both sperm and embryo cryopreservation have become routine procedures in human assisted reproduction and oocyte cryopreservation is being introduced into clinical practice and is getting more and more widely used. Embryo cryopreservation has decreased the number of fresh embryo transfers and maximized the effectiveness of the IVF cycle. The data shows that women who had transfers of fresh and f...

This paper reports studies on the effects of re-vitrification by the CPS (Closed Pulled Straw) method on the development of 4-cell stage mouse embryos. The procedure involved culturing 2-cell mouse embryos in G-1 medium until the 4-cell stage followed by the division of the normal 4-cell stage embryos into a control group (non-vitrified) and two experimental subgroups (vitrified and re-vitrifie...

Sufficient generation of adenosine triphosphate (ATP) by oocytes is critical for fertilization and embryo development. The objective of this study was to determine the effects of supplementing media with L-carnitine, a co-factor required for the metabolism of fatty acids, during the peri-fertilization period on embryo development and energy generation. Firstly, in vitro matured (IVM) porcine oo...
