Self-organized intracellular twisters [PDF]
arXiv, 2023 Life in complex systems, such as cities and organisms, comes to a standstill when global coordination of mass, energy, and information flows is disrupted. Global coordination is no less important in single cells, especially in large oocytes and newly formed embryos, which commonly use fast fluid flows for dynamic reorganization of their cytoplasm. Here,

Human Reproduction Update, 2015 BACKGROUND In a growth phase occurring during most of folliculogenesis, the oocyte produces and accumulates molecules and organelles that are fundamental for the development of the preimplantation embryo.

Coupling of Active Motion and Advection Shapes Intracellular Cargo Transport [PDF]
Phys. Rev. Lett. 109 (2012) 028104, 2012 Intracellular cargo transport can arise from passive diffusion, active motor-driven transport along cytoskeletal filament networks, and passive advection by fluid flows entrained by such motor/cargo motion. Active and advective transport are thus intrinsically coupled as related, yet different representations of the same underlying network structure ...

Ovarian aging: energy metabolism of oocytes
Journal of Ovarian ResearchIn women who are getting older, the quantity and quality of their follicles or oocytes and decline. This is characterized by decreased ovarian reserve function (DOR), fewer remaining oocytes, and lower quality oocytes.

Animal, 2023 The oocyte is the basis of life, supporting development from a fertilized cell to an independent multicellular organism. The oocyte’s competence to drive the first cell cycles postfertilization are critical to embryonic survival and subsequent successful

International Journal of Molecular Sciences, 2016 The physiology of oocyte in vitro maturation remains elusive. Generally, the oocytes have a very low maturation rate under in vitro conditions. In the current study, we found that melatonin promotes the maturation of oocytes in which mitochondria play a ...

Differential Dynamic Microscopy can be applied to Differential Interference Contrast images despite shadowing effects [PDF]
arXiv, 2022 During In Vitro Fertilisation (IVF), combining time-lapse contrast microscopy with suitable image processing techniques could facilitate non-invasive classification of oocyte health, driving oocyte selection to maximise success rates. One image processing technique, Differential Dynamic Microscopy (DDM), has been used in a variety of microscopy ...

Quadrupling efficiency in production of genetically modified pigs through improved oocyte maturation
Proceedings of the National Academy of Sciences of the United States of America, 2017 Significance The efficiency of production of genetically altered piglets for agricultural and biomedical purposes is very low, in large part because of the poor quality of the in vitro-matured oocytes used to initiate the process.

LIMK1/2 inhibitor LIMKi 3 suppresses porcine oocyte maturation [PDF]
PeerJ, 2016 LIMKi 3 is a specific selective LIMK inhibitor against LIMK1 and LIMK2, while LIMK1 and LIMK2 are the main regulators of actin cytoskeleton to participate in many cell activities. However, the effect of LIMKi 3 in porcine oocyte meiosis is still unclear.

Grading of Mammalian Cumulus Oocyte Complexes using Machine Learning for in Vitro Embryo Culture [PDF]
arXiv, 2016 Visual observation of Cumulus Oocyte Complexes provides only limited information about its functional competence, whereas the molecular evaluations methods are cumbersome or costly. Image analysis of mammalian oocytes can provide attractive alternative to address this challenge.
