Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

open access: yesFEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Congelação de ovócitos desnudados ou não, maturos e imaturos de bovinos, utilizando o Etileno Glicol pelo método convencional Freezing of either naked or no-naked, matured and immature oocytes from cows, using the Ethylene Glycol by the conventional method

open access: yesRevista Brasileira de Zootecnia, 2004
Objetivou-se avaliar os efeitos da criopreservação pelo método convencional em ovócitos imaturos e maturados in vitro. Utilizou-se ovócitos provenientes de ovários de vacas abatidas em matadouro, distribuídos em seis tratamentos: ovócitos não-congelados ...

Effect of harvesting technique and presence or absence of corpus luteum on in vitro development after parthenogenetic activation of oocytes recovered from buffalo ovaries [PDF]

open access: yesVeterinary World, 2014
Aim: The present study was aimed at assessing the influence of three oocyte harvesting (aspiration, puncture and slicing) methods and presence or absence of corpus luteum (CL) on recovery efficiency and subsequent in vitro maturation and parthenogenetic ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

The Exploration of miRNAs From Porcine Fallopian Tube Stem Cells on Porcine Oocytes

open access: yesFrontiers in Veterinary Science, 2022
Fallopian tube is essential to fertilization and embryonic development. Extracellular vesicles (EVs) from Fallopian tube containing biological regulatory factors, such as lipids, proteins and microRNAs (miRNAs) serve as the key role.

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms

open access: yesAdvanced Materials, EarlyView.
This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

MITOCHONDRIA IN MAMMALIAN OOCYTES AND EARLY EMBRYOS. A REVIEW ON MORPHOLOGICAL AND FUNCTIONAL STUDIES

open access: yesEuromediterranean Biomedical Journal, 2018
Mitochondria are the most abundant organelles in mammalian oocytes and early embryos. The central role of mitochondria in the establishment of developmental competence of oocytes and early embryos come out from basic research in experimental models and ...

CCDC41 Drives Oocyte Meiotic Progression by Promoting Rab11a/Rab7‐Positive Vesicle Fusion with Target Membranes

open access: yesAdvanced Science, EarlyView.
CCDC41 is essential for meiotic maturation in mouse oocytes through regulating Rab7‐positive endosomes fusion with lysosomes and Rab11a‐positive vesicle fusion with the plasma membrane. Abstract Coiled‐coil domain‐containing protein 41 (CCDC41), a core component of centriolar distal appendages involved in centriole assembly and ciliary vesicle docking,

Bisphenol B Exposure Induces Miscarriage by Suppressing Migration/Invasion and Migrasome Formation

open access: yesAdvanced Science, EarlyView.
BPB (Bisphenol B) exposure up‐regulates ER (estrogen receptor) levels, enhances its interactions with the lnc‐HZ04 promoter region, and thus promotes ER‐mediated lnc‐HZ04 transcription. Subsequently, lnc‐HZ04 suppresses TCF4 (transcription factor 4)‐mediated PKCA (protein kinase C alpha) transcription and subsequently suppresses migration/invasion and ...

Annual fecundity, batch fecundity, and oocyte atresia of Atka mackerel (Pleurogrammus monopterygius) in Alaskan waters [PDF]

open access: yes, 2007
Annual potential fecundity, batch fecundity, and oocyte atresia were estimated for Atka mackerel (Pleurogrammus monopterygius) collected in Alaskan waters during 1993−94.
