Exopolysaccharide of Enterococcus faecium L15 promotes the osteogenic differentiation of human dental pulp stem cells via p38 MAPK pathway

Stem Cell Research & Therapy, 2022
Background Bone has important functions in the body. Several researchers have reported that the polysaccharides and lipopolysaccharide derived from microbes can promote osteogenic differentiation of stem cells.

Prostaglandin E2 affects in vitro maturation of bovine oocytes

Reproductive Biology and Endocrinology, 2020
The role of prostaglandin E2 (PGE2) in the successful resumption of oocyte meiosis and cumulus expansion has been well-documented. However, there remains very little information available on the influence of PGE2 on other processes that occur during ...

Delivery of water and volatiles to the terrestrial planets and the Moon [PDF]

Solar System Research, 2018, v. 52, N 5, p. 392-400, 2020
From modeling the evolution of disks of planetesimals under the influence of planets, it has been shown that the mass of water delivered to the Earth from beyond Jupiter's orbit could be comparable to the mass of terrestrial oceans. A considerable portion of the water could have been delivered to the Earth's embryo, when its mass was smaller than the ...

Canine sperm motility is associated with telomere shortening and changes in expression of shelterin genes

BMC Veterinary Research, 2023
Background Motion quality is a critical property for essential functions. Several endogenous and exogenous factors are involved in sperm motility. Here, we measured the relative telomere length and evaluated the gene expression of its binding-proteins ...

Integrative Single-Cell Transcriptomic Analysis of Human Fetal Thymocyte Development

Frontiers in Genetics, 2021
Intrathymic differentiation of T lymphocytes begins as early as intrauterine stage, yet the T cell lineage decisions of human fetal thymocytes at different gestational ages are not currently understood. Here, we performed integrative single-cell analyses

Expression of factors involved in apoptosis and cell survival is correlated with enzymes synthesizing lysophosphatidic acid and its receptors in granulosa cells originating from different types of bovine ovarian follicles

Reproductive Biology and Endocrinology, 2017
Background Lysophosphatidic acid (LPA) regulates reproductive processes in the cow. Ovarian granulosa cells play a pivotal role in follicle growth and development.

New insights into posttranslational modifications of proteins during bull sperm capacitation

Cell Communication and Signaling, 2023
Background Due to the unique nature of spermatozoa, which are transcriptionally and translationally silent, the regulation of capacitation is based on the formation of posttranslational modifications of proteins (PTMs).
