Development of In vitro Maturation and In vitro Growth Culture Media Using Goat Colostrum [PDF]

BIO Web of Conferences
This research aims to develop a more optimal in vitro maturation (IVM) oocyte and in vitro growth (IVG) follicle culture medium through the utilization of goat colostrum as an additive to the standard IVM and IVG culture medium.

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

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Effect of single versus grouped culture of human cumulus–oocyte complexes in PCOS women treated with biphasic in vitro maturation: A sibling oocyte pilot study

Reproductive Medicine and Biology
Purpose This study investigated the differences in the maturation rate of single versus grouped cumulus–oocyte complexes (COCs) culture methods for capacitation in vitro maturation (CAPA‐IVM) in women with polycystic ovary syndrome (PCOS).

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Effects of gonadotropin-exposed medium with high concentrations of progesterone and estradiol-17b on in vitro maturation of canine oocytes

, 2009
During the process of maturation in the oviduct, canine oocytes in the germinal vesicle stage are exposed to decreasing levels of estradiol-17b and increasing levels of progesterone.

Improvement of oocyte competence and in vitro oocyte maturation with EGF and IGF-I in Guinea pig model

, 2023
2023 Acuerdos transformativos CRUEIn vitro maturation (IVM) system is an alternative method to superovulation protocols to obtain mature oocytes. Epidermal Growth Factor (EGF) and Insulin-like Growth Factor I (IGF-I) have been widely used in IVM medium ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Pyrethroids cypermethrin, deltamethrin and fenvalerate have different effects on in vitro maturation of pig oocytes at different stages of growth

Animal, 2013
Pesticides can significantly harm reproduction in animals and people. Pyrethroids are often used as insecticides, and their toxicity for mammals is considered to be low.
