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.

Bone marrow mesenchymal stromal cells were aspirated from immature male green fluorescent protein transgenic rats and cultured in a monolayer. Four weeks after the creation of the osteochondral defect, the rats were divided into three groups of 18: the control group, treated with an intra-articular injection of phosphate-buffered saline only; the drilling group, treated with an intra-articular ...

Introduction: Hematopoiesis is an on going process mammalian marrow system. A few cells from the nucleated cells of bone marrow are hematopoietic cells which include primary stem cells, precursor cells and progenitor cells. Primary stem cells and progenitor cells are able to produce colonies in culture medium (CFU-C) and irradiated mouse spleen (CFU-S). A hematopoietic cell is alive and act...

Bone marrow prothymocytes from me/me and mev/mev mutant mice fail to generate thymocytes in irradiated (600 rad) +/+ wild-type recipients after intravenous injection. However, these same prothymocytes readily generate thymocytes after intrathymic injection. The results of the present study demonstrate that this apparent defect in the thymus-homing capacity of mev/mev prothymocytes can be correc...

In 79 consecutive patients with unicameral bone cysts we compared the results of aspiration and injection of bone marrow with those of aspiration and injection of steroid. All were treated by the same protocol. The only difference was the substance injected into the cysts. The mean radiological follow-up to detect activity in the cyst was 44 months (12 to 108). Of the 79 patients, 14 received a...

We prospectively evaluated the percutaneous injection of autogenous bone marrow for the treatment of active simple bone cysts in ten consecutive children with cysts in the proximal humerus, proximal femur or tibia. The treatment included percutaneous biopsy, aspiration of fluid and the injection of autogenous bone marrow aspirated from the iliac crest. All the patients became painfree after a m...

BACKGROUND The treatment of simple bone cysts (SBC) in children varies significantly among physicians. This study examined which procedure is better for the treatment of SBC, using a decision analysis based on current published evidence. METHODS A decision tree focused on five treatment modalities of SBC (observation, steroid injection, autologous bone marrow injection, decompression, and cur...

BACKGROUND Intraoperative cardiovascular deterioration as a result of pulmonary embolization of bone marrow fat is a potentially serious complication during vertebroplasty. The release of fatty material and thromboplastin from the bone marrow cavity during vertebroplasty may activate the coagulation cascade resulting in thrombogenesis, and pharmacological prophylaxis may therefore prevent cardi...

The purpose of this paper is to perform an evidence based review for treatment of unicameral bone cysts. A search of MEDLINE (1966 to 2009) was conducted and the studies were classified according to levels of evidence. This review includes only comparative Level I-III studies. The systematic review identified 16 studies. There is one level I study, one level II study and the remaining 14 studie...
