Background: Embryonic stem (ES) cells have the potential to produce unlimited numbers of surrogate insulin-producing cells for cell replacement therapy of type 1 diabetes mellitus. The impact of the in vivo environment o...

ABSTRACT Retinal ganglion cell (RGC) degeneration represents a cardinal etiology of irreversible vision loss in glaucoma, where efficacious regenerative therapies remain scarce. RGC replacement therapy holds promise for ...

We report a technology to form human embryoid bodies (hEBs) from singularized human embryonic stem cells (hESCs) without the use of the p160 rho-associated coiled-coil kinase inhibitor (ROCKi) or centrifugation (spin). h...

In this study, we explore the neuroprotective and modulatory potential of graphenic materials (GMs) in terms of the maturation of dopaminergic neurons and their capacity to counteract the cellular stress induced by toxin...

Abstract Background Acute liver failure (ALF) is a life-threatening syndrome characterized by rapid deterioration of liver function, resulting in high mortality and posing a substantial global health burden. Human embryo...

The theoretically unlimited spatial resolution of fluorescence nanoscopy often comes at the expense of time, contrast and increased dose of energy for recording. Here, we developed MoNaLISA, for Molecular Nanoscale Live ...

Mechanical forces drive and modulate a wide variety of processes in eukaryotic cells including those occurring in the nucleus. Relevantly, forces are fundamental during development since they guide lineage specifications...

Abstract DNA replication timing (RT) often correlates with transcription during cell fate transitions, yet notable exceptions indicate a complex relationship. Using a reductionist system in mouse embryonic stem cells, we...

Parthenogenetic embryos are an ethically acceptable alternative for the derivation of human embryonic stem cells. In this work, we propose a new strategy to produce bovine parthenogenetic embryos inhibiting the emission ...

AS THE possibility of therapeutic cloning in humans has just been demonstrated by a Corean group of researchers, the paper argues that biotechnologies of that kind may contribute to alleviate the chronic shortage of orga...

This essay analyses the asymmetrical relationship between the time of scientific research and the time of the different segments interested in their results, focusing mainly on necessity to establish technical consensus ...

Human blastocyst-derived, pluripotent cell lines are described that have normal karyotypes, express high levels of telomerase activity, and express cell surface markers that characterize primate embryonic stem cells but ...

This report describes the establishment directly from normal preimplantation mouse embryos of a cell line that forms teratocarcinomas when injected into mice. The pluripotency of these embryonic stem cells was demonstrat...

Methylation Mediation Methylation of cytosine bases, 5-methylcytosine (5mC), in DNA plays an important regulatory role in mammalian genomes. Methylation patterns are often inherited across generations, but they can also ...

Kidney diseases, related to high morbidity and mortality, are one of the diseases that should be primarily investigated. Development of acute and chronic kidney diseasesis due to lack of functioning renal repair mechan...

Biofabricated scaffolds facilitate bona fide cellular interactions, cell type specification, and the formation of three-dimensional tissue architecture from human pluripotent stem cells (hPSCs). However, xenogenic biomat...
