Background And Objectives: The mesenchymal stem cells derived from peripheral blood (PB) have been recognized as a promising source for allogeneic cell therapy. The aim of this study was to investigate the isolation, growth and differentiation ability of peripheral blood-isolated mesenchymal stem cells.
Methods: The mononuclear cells were purified from fresh peripheral blood using density gradient centrifugation then cultured in a suitable medium, expanded and characterized. In the following, these cells were cultured in specific adipogenic and osteogenic differentiation media.
Results And Conclusion: In spite of the absence of any stimulating factor, the cells adhered to the flasks and developed a rather homogeneous, spindle-shaped morphology after consecutive passages. The cells were confirmed to have mesenchymal phenotype by expression of specific markers (CD90, CD105, and CD73) and absence of CD45 marker, which is specific for hematopoietic stem cells. They could differentiate into lineage-specific committed cells (osteoblasts and adipocytes).According to the findings, the conventional, labour-intensive and time-consuming approaches are not necessary to obtain an optimal number of cells from peripheral blood. This relatively accessible and minimally invasive source of stem cells may open a new era for practical exploitation in regenerative medicine.

Unlabelled: Di(2-ethhylhexyl) phthalate (DEHP) is a common plastic rubberizer. DEHP leaches from plastic matrices and is under increasing scrutiny as numerous studies have linked it to negative human health manifestations. Coxsackievirus B3 (CVB) is a human pathogen that typically causes subclinical infections but can sometimes cause severe diseases such as pancreatitis, myocarditis, and meningoencephalitis.

Background: Varicella can lead to severe complications in immunocompromised children, including those undergoing hematopoietic stem cell transplantation (HSCT) or chemotherapy. Preventing primary varicella zoster virus (VZV) infection is crucial in these populations to mitigate morbidity and mortality. This study aimed to evaluate the immunogenicity and safety of the live attenuated MAV/06 varicella vaccine in pediatric patients post-HSCT and post-chemotherapy.

Background/objectives: The aim was to study the possibilities of biomedical application of gadolinium oxide nanoparticles (GdO NPs) synthesized under industrial conditions, and evaluate their physicochemical properties, redox activity, biological activity, and safety using different human cell lines.
Methods: The powder of GdO NPs was obtained by a process of thermal decomposition of gadolinium carbonate precipitated from nitrate solution, and was studied using transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy, mass spectrometry, and scanning electron microscopy (SEM) with energy dispersive X-ray analyzer (EDX). The redox activity of different concentrations of GdO NPs was studied by the optical spectroscopy (OS) method in the photochemical degradation process of methylene blue dye upon irradiation with an optical source.

The treatment of articular cartilage damage has always represented a problem of considerable practical interest for orthopedics. Over the years, many surgical techniques have been proposed to induce the growth of repairing tissue and limit degeneration. In 1994, the turning point occurred: implanted autologous cells paved the way for a new treatment option based more on regeneration than repair.
