Unraveling the impact of human cerebrospinal fluid on human neural stem cell fate.

Human neural stem/progenitor cells (hNSCs) can potentially treat neurological diseases, but their low survival and proliferation rates after transplantation remain challenging. In our study, we preincubated hNSCs with the human cerebrospinal fluid (CSF) to obtain closer to the physiological brain environment and to assess NSC fate and their therapeutic abilities , , and . We observed significant changes in the differentiation, migratory, and secretory potential of CSF-treated hNSCs, as well as their elevated neuroprotective potential after co-culture with ischemically damaged by oxygen-glucose deprivation (OGD) organotypic rat hippocampal slices culture (OHC) in comparison to the cells cultured in the standard conditions.

Deciphering the impact of cerebrospinal fluid on stem cell fate as a new mechanism to enhance clinical therapy development.

Neural stem cells (NSCs) hold a very significant promise as candidates for cell therapy due to their robust neuroprotective and regenerative properties. Preclinical studies using NSCs have shown enough encouraging results to perform deeper investigations into more potential clinical applications. Nevertheless, our knowledge regarding neurogenesis and its underlying mechanisms remains incomplete.

Evaluation of the Optimal Manufacturing Protocols and Therapeutic Properties of Mesenchymal Stem/Stromal Cells Derived from Wharton's Jelly.

Wharton's jelly (WJ) from the umbilical cord (UC) is a good source of mesenchymal stem/stromal cells (MSCs), which can be isolated and used in therapy. Current knowledge shows that even small changes in the cell environment may result in obtaining a subpopulation of cells with different therapeutic properties. For this reason, the conditions of UC transportation, cell isolation, and cultivation and the banking of cells destined for clinical use should be unified and optimized.

Should We Consider Them as a Threat? Antimicrobial Resistance, Virulence Potential and Genetic Diversity of spp. Isolated from Varsovian Dogs.

Campylobacteriosis seems to be a growing problem worldwide. Apart from the most common sources of numerous species, such as poultry and other farm animals, dogs may be an underrated reservoir of this pathogen. Our goal was to establish the frequency of occurrence, antimicrobial resistance, and detection of chosen virulence factor genes in genomes of canine isolates.

Critical factors responsible for the therapeutic effect of mesenchymal stem/stromal cells in central nervous system disorders.

Nowadays it is observed that the number of stem-cell based experimental therapies in neurodegenerative disorders is massively increasing. Most of the clinical trials registered to date have been based on autologous mesenchymal stem/stromal cells (MSC) obtained from somatic tissues. In the conducted clinical trials neither serious side effects, nor statistically significant improvement were observed.
