[FeFe]‐Hydrogenase In Vitro Maturation
Angewandte Chemie, 2022AbstractThe [FeFe]‐hydrogenase H‐cluster is a complex organometallic cofactor whose assembly and installation requires three dedicated accessory proteins referred to as HydE, HydF, and HydG. The roles of these maturases and the precise mechanisms by which they synthesize and insert the H‐cluster are not fully understood.

Neuroscience Letters, 1989
Cocultures of spinal cord neurons and muscle cells taken from rat embryos were used for in vitro reproduction of embryonic synapses. This system did not display the synaptic maturation characteristics of postnatal development: decreased multiple innervation and the presence of a developed subneural apparatus.

In Vitro Maturation of Oocytes
Seminars in Reproductive Medicine, 2005In vitro maturation of oocytes is a safe and effective treatment offered in some fertility centers for assisted reproduction, where immature oocytes are retrieved from unstimulated ovaries. Therefore, the procedure avoids ovarian stimulation with expensive gonadotropins, side effects of the medications, and risks such as ovarian hyperstimulation ...

The Obstetrician & Gynaecologist, 2013
Key content In vitro maturation is an alternative to in vitro fertilisation for young women with polycystic ovary syndrome and young ovulatory women. In vitro maturation accomplishes the maturation of immature oocytes in the laboratory, thus minimising or avoiding gonadotrophin stimulation and the associated cost, side‐effects and risks.

Maturation of the reticulocyte in vitro
Journal of Cell Science, 1984ABSTRACT The maturation of reticulocytes into erythrocytes was demonstrated in vitro. Reticulocytosis was induced in rats by repeated bleeding or by phenylhydrazine injections. Whole blood samples were then incubated for 2 days at 37 °C.

In vitro maturation of mammalian spermatozoa
Reviews of Reproduction, 1996During epididymal transit, mammalian spermatozoa undergo maturation and acquire full fertilizing capacity. The contribution of factors from the epididymal epithelium appears to be essential for this process. Although complete in vitro maturation of epididymal spermatozoa has not been achieved, stages of maturation can be induced under various ...

Current Opinion in Obstetrics and Gynecology, 2002
In contrast to conventional assisted reproduction techniques in which metaphase II oocytes are retrieved for fertilization in vitro, during the in-vitro maturation of oocytes, immature germinal vesicle stage oocytes are retrieved and matured in the laboratory before fertilization and embryo transfer.

In vitro maturation: a committee opinion
Fertility and Sterility, 2021The results of in vitro maturation (IVM) investigations suggest the potential for wider clinical application. This document discusses the efficacy of IVM as reported in the published literature to date. This document replaces the document of the same name, last published in 2013.

Maturation of mouse sperm in vitro
Journal of Experimental Zoology, 1974AbstractPreincubation of sperm in medium for three hours before mixing with ova increased the number of ova fertilized after one hour, thus indicating that sperm maturation occurs in vitro. The presence of cumulus cells increased the proportion of ova fertilized as observed at two and at three hours after the addition of sperm.

In vitro maturation of horse oocytes
Theriogenology, 1994Ovaries collected from slaughtered mares of unknown reproductive history were transported to the laboratory, and their oocytes were recovered and cultured in modified TCM 199 supplemented with 20% horse serum and additional granulosa cells. To characterize the ovaries, the size and number of follicles were counted.
