Heat shock during in vitro maturation of bovine oocytes disturbs bta-miR-19b and DROSHA transcripts abundance after in vitro fertilization.

Reproduction in domestic animals = Zuchthygiene, 2021
While microRNAs (miRNAs) are a class of non-coding RNAs important for embryo development, the relationship between them and heat stress during oocyte maturation has not yet been established.

Granulosa cells affect in vitro maturation and subsequent parthenogenetic development of buffalo (Bubalus bubalis) oocytes.

Reproduction in domestic animals = Zuchthygiene, 2021
Granulosa cells (GCs) play a crucial role in follicular development and atresia. Previous studies have showed that GCs in the form of monolayer influenced in vitro maturation (IVM) of oocytes. However, the effects of GCs in the form of conditioned medium

Effects of individual or in-combination antioxidant supplementation during in vitro maturation culture on the developmental competence and quality of porcine embryos.

Reproduction in domestic animals = Zuchthygiene, 2021
The oocyte maturation process requires a high supply of energy, which generates reactive oxygen species (ROS), adversely affecting oocyte and embryo development.

Ovum pick-up and in vitro maturation in spotted paca (Cuniculus paca - Linnaeus, 1766).

Reproduction in domestic animals = Zuchthygiene, 2020
We tested FSHp, eCG and FSHp+eCG to establish ovum pick-up (OPU) and in vitro maturation method in spotted paca. Eight healthy adult females were subjected to each of four treatments to stimulate ovarian follicular growth. All females were subjected to a

Biphasic in-vitro maturation: an advancement over traditional in-vitro maturation

Y hoc Thanh pho Ho Chi Minh
Culture conditions for standard in-vitro maturation (IVM) have remained largely unchanged for more than 50 years and are non-physiological, limiting the success of this form of assisted reproductive technology (ART).

Reactive Oxygen Species Generation and Use of Antioxidants during In Vitro Maturation of Oocytes

International Journal of Fertility and Sterility, 2017
In vitro maturation (IVM) is emerging as a popular technology at the forefront of fertility treatment and preservation. However, standard in vitro culture (IVC) conditions usually increase reactive oxygen species (ROS), which have been implicated as one ...

Effects of Resveratrol on In Vitro Maturation of Porcine Oocytes and Subsequent Early Embryonic Development following Somatic Cell Nuclear Transfer.

Reproduction in domestic animals = Zuchthygiene, 2019
As a natural plant-derived antitoxin, resveratrol possesses several pharmacological activities. This study aimed to evaluate the effects of resveratrol addition on nuclear maturation, oocyte quality during in vitro maturation (IVM) of porcine oocytes ...

A new three-dimensional glass scaffold increases the in vitro maturation efficiency of buffalo (Bubalus bubalis) oocyte via remodeling the extracellular matrix and cell connection of cumulus cells.

Reproduction in domestic animals = Zuchthygiene, 2019
At present, many three-dimensional (3D) culture systems have been reported improving the oocyte quality of in vitro maturation (IVM), yet the mechanism still needs to be further explored.

Influence of growth differentiation factor 9 and bone morphogenetic protein 15 on in vitro maturation of canine oocytes

Reproduction in domestic animals = Zuchthygiene, 2018
Growth differentiation factor 9 (GDF-9) and bone morphogenetic protein 15 (BMP-15) have pivotal roles in oocyte development in many species, therefore the aim was to investigate these factors during in vitro maturation (IVM) of canine oocytes.
