HIGHLIGHTS Extracellular vesicles (EV) from human bone marrow were able to reduce airway inflammation in a mouse model. Treatment applied by Intratracheal injection was more effective than systemic administration caudal vein injection. IT of EVs appears act therapeutically restoring the basal BAL cell counts and attenuating early lung remodeling.

The medullary niche is a complex ecosystem that essential to maintain homeostasis for resident cells. Indeed, the bone marrow, which includes extracellular matrix and various cell types, such as mesenchymal stem cells, osteoblasts, endothelial deeply involved in hematopoietic regulation through direct cell-cell interactions, well cytokine production. To closely mimic this vivo structure conduct...

BACKGROUND: Stem cell therapy in small animal medicineis still in its infancy and few in vitro and in vivo research projectsregarding animal Mesenchymal Stem Cells (MSCs) have beencarried out. On the other hand, Cell tracking is the first step of thecell-based therapies and is essential to recognize cell fate posttransplantation. OBJECTIVES: The aim of this study was toisolate, characterize, an...

introduction: in this study, the effect of para-nonylphenol as an environmental pollutant on viability, morphology and proliferation of bone marrow mesenchymal stem cells was investigated. methods: bone marrow mesenchymal stem cells of rat were treated with the 0.5, 1, 2.5, 3.5 and 5 μm of paranonylphenol for a period of 21 days, then the viability of the cells were estimated using trypan blue ...

Adult bone marrow contains progenitor cells that can extricate themselves from their bone marrow cavity niche, and engraft within foreign tissues, whereupon they produce specific differentiated adult lineages. Bone marrow engraftment is upregulated with increasing regenerative pressure, which has triggered speculation as to the therapeutic potential of bone marrow cells. In this thesis, I descr...

Mesenchymal stem cells (MSCs) - usually obtained from bone marrow - often require expansion culture. Our protocol uses clinical grade urokinase to degrade clots in the bone marrow and release MSCs for further use. This protocol provides a rapid and inexpensive alternative to bone marrow resampling. Bone marrow is a major source of MSCs, which are interesting for tissue engineering and autologou...

Bone marrow-derived cells including osteoblastic progenitors can be concentrated rapidly from bone marrow aspirates using the surface of selected implantable matrices for selective cell attachment. Concentration of cells in this way to produce an enriched cellular composite graft improves graft efficacy. The current study was designed to test the hypothesis that the biologic milieu of a bone ma...
