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

open access: yesStem 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.

Phases of reprogramming

open access: yesStem Cell Research, 2014
Despite advances in the field of somatic cell reprogramming, an understanding and exploration of the underlying mechanisms governing this process are only recently emerging. It is now increasingly apparent that key sequential events correlate with the reprogramming process; a process previously thought to be random and unpredictable is now looking, to ...

Epigenetic impairments in development of parthenogenetic preimplantation mouse embryos

open access: yesThe Journal of Reproduction and Development, 2018
Parthenogenesis is an activation process of oocytes that occur without the participation of sperm. Evidence suggests that normal development of embryos requires proper expression of several imprinted genes inherited from both the paternal and maternal ...

Enzymatic isolation of porcine preantral follicles impairs oocyte viability and long-term in vitro growth

open access: yesThe Journal of Reproduction and Development
The enzymatic isolation of preantral follicles (PAFs) is considered the most efficient method for retrieving a large number of intact follicles, offering significant advantages in terms of yield and processing time.

Autophagosome Biogenesis

open access: yesCells, 2023
Autophagy–the lysosomal degradation of cytoplasm–plays a central role in cellular homeostasis and protects cells from potentially harmful agents that may accumulate in the cytoplasm, including pathogens, protein aggregates, and dysfunctional organelles ...

Repressors of reprogramming

open access: yesWorld Journal of Stem Cells, 2015
Induced pluripotent stem cells (iPSCs) have been the focal point of ever increasing interest and scrutiny as they hold the promise of personalized regenerative medicine. However, creation of iPSCs is an inefficient process that requires forced expression of potentially oncogenic proteins.

High Therapeutic and Esthetic Properties of Extracellular Vesicles Produced from the Stem Cells and Their Spheroids Cultured from Ocular Surgery-Derived Waste Orbicularis Oculi Muscle Tissues

open access: yesAntioxidants, 2021
Extracellular vesicles (EVs) are paracrine factors that mediate stem cell therapeutics. We aimed at evaluating the possible therapeutic and esthetic applications of EVs prepared from the waste human facial tissue-derived orbicularis oculi muscle stem ...

[Reprogramming and epigenesis].

open access: yesMedecine sciences : M/S, 2005
Les succès récents du clonage animal démontrent que le noyau d’une cellule somatique adulte différenciée peut retourner à un état de type embryonnaire, lui permettant de repasser par les étapes qui conduisent à la naissance d’un animal viable et normal.

Improving porcine in vitro blastocyst development using fetal bovine serum, amino acids, and insulin-transferrin-selenium

open access: yesThe Journal of Reproduction and Development
In vitro production of porcine-hatched blastocysts is important for various applications. However, the mechanobiology of blastocoel expansion and hatching remains poorly understood.

Isolation of female germline stem cells from porcine ovarian tissue and differentiation into oocyte-like cells

open access: yesThe Journal of Reproduction and Development, 2019
Historically, it had been widely accepted that the female mammalian ovary contained a limited number of oocytes that would reduce over time, without the possibility of replenishment. However, recent studies have suggested that female germline stem cells (
