In-vitro maturation of human oocytes

Reproductive BioMedicine Online, 2004
Immature human oocytes can be matured and fertilized in vitro. However, subsequent embryonic development is different when the immature oocytes are retrieved in different situations. Exposure to the LH surge in vivo may be important for the oocytes to acquire the competence for maturation and subsequent embryonic development.

Studies on erythropoiesis II. In vitro studies on red cell proliferation under varied oxygen tension [PDF]

, 1964
For the purpose to reveal the mechanism of the stimulated erythropoiesis in anemic condition, the author observed the numerical changes of the erythroblasts from normal rabbit bone marrow cultured under the environment of varied oxygen tensions, and ...

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.

Early vessel destabilization mediated by Angiopoietin-2 and subsequent vessel maturation via Angiopoietin-1 induce functional neovasculature after ischemia. [PDF]

, 2013
We assessed whether Angiopoietin-2 (Ang2), a Tie2 ligand and partial antagonist of Angiopoietin-1 (Ang1), is required for early vessel destabilization during postischemic angiogenesis, when combined with vascular growth factors.

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 vitromaturation: Clinical applications [PDF]

Clinical and Experimental Reproductive Medicine, 2013
Oocyte in vitro maturation (IVM) is an assisted reproductive technology in which oocytes are retrieved from the antral follicles of unstimulated or minimally stimulated ovaries. IVM of human oocytes has emerged as a promising procedure. This new technology has advantages over controlled ovarian stimulation such as reduction of costs, simplicity, and ...

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 oocyte maturation in vitro

The International Journal of Developmental Biology, 2012
Oocytes from medium-sized antral follicles have already completed their growth phase and, if released from the follicular environment and cultured in vitro, are able to resume the meiotic process and mature. However, in vitro maturation (IVM) does not entirely support all the nuclear and cytoplasmic changes that occur physiologically as an effect of ...
