Melatonin Restores the Developmental Competence of Heat Stressed Porcine Oocytes, and Alters the Expression of Genes Related to Oocyte Maturation

Animals, 2021
Melatonin enhances the quality and in vitro maturation (IVM) of oocytes under heat stress (HS), but the mechanism of melatonin in reducing HS injury on oocytes is not fully understood.

Progesterone Promotes In Vitro Maturation of Domestic Dog Oocytes Leading to Successful Live Births

Life, 2022
Gene-edited dogs are promising models for biomedical research because they have hundreds of genetic diseases that are similar to humans. A common method for producing gene-edited dogs is assisted reproductive technology (ART) using in vivo oocytes or ...

In vitro developmental competence of prepubertal goat oocytes cultured with recombinant activin-A

Animal, 2014
The present study was designed to evaluate the effect of activin-A during the in vitro oocyte maturation (IVM) and in vitro embryo culture (IVC) on nuclear maturation, blastocyst yield and blastocyst quality of prepubertal goat oocytes.

Meiotic Development of Canine Oocytes from Poly-Ovular and Mono-Ovular Follicles after In Vitro Maturation

Animals, 2023
Poly-ovular follicles are defined as those with more than one oocyte present in single follicles. The occurrence frequency of this follicle type is higher in canines than that in other species. This study aimed to evaluate the in vitro meiotic maturation

Human natural killer cell committed thymocytes and their relation to the T cell lineage. [PDF]

, 1993
Recent studies have demonstrated that mature natural killer (NK) cells can be grown from human triple negative (TN; CD3-, CD4-, CD8-) thymocytes, suggesting that a common NK/T cell precursor exists within the thymus that can give rise to both NK cells ...

Altered cytoplasmic maturation in rescued in vitro matured oocytes

Human Reproduction, 2019
Do culture conditions affect cytoplasmic maturation in denuded immature non-GV oocytes?The maturation rate of denuded non-GV oocytes is not affected by culture media, but in vitro maturation seems to alter the mitochondrial membrane potential, endoplasmic reticulum (ER) and actin cytoskeleton compared with in vivo maturation.In vitro maturation of ...

In vitro production of bovine embryos derived from individual donors in the Corral® dish [PDF]

, 2017
Background: Since the identity of the embryo is of outmost importance during commercial in vitro embryo production, bovine oocytes and embryos have to be cultured strictly per donor.

Interleukin-2 induces the in vitro maturation of human pluripotent stem cell-derived intestinal organoids

Nature Communications, 2018
Human pluripotent stem cell (hPSC)-derived intestinal organoids (hIOs) form 3D structures organized into crypt and villus domains, making them an excellent in vitro model system for studying human intestinal development and disease. However, hPSC-derived
