Isolation and long-term maintenance of hepatic progenitor cells (HPCs) from healthy, non-injured adult livers remains challenging due to the lack of specific surface markers for selection and a limited understanding of the mechanisms for maintaining self-renewal. Previously, we identified a Sca-1 positive, bipotent HPC population in the peri-portal region of adult liver, and found MAPK/ERK and ...

Porcine induced pluripotent stem cells (iPSCs) provide useful information for translational research. The quality of iPSCs can be assessed by their ability to differentiate into various cell types after chimera formation. However, analysis of chimera formation in pigs is a labor-intensive and costly process, necessitating a simple evaluation method for porcine iPSCs. Our previous study identifi...

Conventional human induced pluripotent stem cells (hiPSCs), reprogrammed from somatic cells by induced expression of Oct4, Sox2, Klf4, and c-Myc, are phenotypically different from mouse embryonic stem cells (ESCs). In mice, culture in N2B27 serum-free 2i media (mitogen-activated protein kinase/extracellular signal-regulated kinase and glycogen synthase kinase 3 inhibitors; PD0325901 and CHIR990...

The adverse effects of high environmental temperature exposure on animal reproductive functions have been concerned for many decades. However, the molecular basis of heat stress (HS)-induced decrease of sperm motility has not been entirely elucidated. We hypothesized that the deteriorate effects of HS may be mediated by damage of mitochondrial function and ATP synthesis. To test this hypothesis...

BACKGROUND Recent advances in stem cell technology afford an unlimited source of neural progenitors and glial cells for cell based therapy in central nervous system (CNS) disorders. However, current differentiation strategies still need to be improved due to time-consuming processes, poorly defined culture conditions, and low yield of target cell populations. METHODOLOGY/PRINCIPLE FINDINGS Th...

It has been previously reported that human embryonic fibroblasts and mouse embryonic fibroblasts can be converted into neuronal cells using chemical agents, along with forced expression specific transcriptional factors. However, the materials required for reprogramming in these approaches presents major technical difficulties and safety concerns. The current study investigated whether a cocktai...

Myocardial infarction (MI) is the leading cause of death worldwide. However, current therapies are unable to restore function injured myocardium. Advanced approaches, such as stimulation cardiomyocyte (CM) proliferation promising, but suffer from poor pharmacokinetics and possible systemic adverse effects. Nanomedicines can be a solution above-mentioned drawbacks. targeting cardiac tissue still...

Cardiac fibrosis is a pathological process associated with the development of heart failure. TGF-? and WNT signaling have been implicated in pathogenesis cardiac fibrosis, however, little known about molecular cross-talk between these two pathways. The aim this study was to examine effect exogenous canonical WNT3a non-canonical WNT5a TGF-?-activated human fibroblasts. We found that induced ?-ca...

Recombinant matrices have enabled feeder cell-free maintenance cultures of human pluripotent stem cells (hPSCs), with laminin 511-E8 fragment (LM511-E8) being widely used. However, we herein report that hPSCs maintained on LM511-E8 resist differentiating to multipotent hematopoietic progenitor (HPCs), unlike LM421-E8 or LM121-E8. The latter two LM-E8s bound weakly compared and activated the can...

Cattle have emerged as one of the most important domestic animals widely used for meat, milk, and fur. Derivation bovine pluripotent stem cells (PSCs) can be applied in drug selecting human disease modeling facilitated agriculture-related applications such production genetically excellent cattle by gene editing. Extended PSCs (EPSCs), capable differentiating into embryonic extraembryonic parts,...
