Oxygen delivery augmented bone formation from transplanted bone marrow

Pedicled bone flap formation using transplanted bone marrow stromal cells.

HYPOTHESIS Transplanted osteoprogenitor cells derived from cultured bone marrow stromal cells (BMSCs) can be used to fabricate pedicled bone flaps. DESIGN Prospective, randomized experimental trials. SETTING Basic science research laboratory. MATERIALS Immunodeficient female NIH-Bg-Nu-Xid mice, aged 3 months. INTERVENTION The BMSCs were harvested from the long bones of C57Bl/6 transgeni...

Transplanted Bone Marrow

Dual growth factor delivery and controlled scaffold degradation enhance in vivo bone formation by transplanted bone marrow stromal cells.

Supraphysiological concentrations of exogenous growth factors are typically required to obtain bone regeneration, and it is unclear why lower levels are not effective. We hypothesized that delivery of bone progenitor cells along with appropriate combinations of growth factors and scaffold characteristics would allow physiological doses of proteins to be used for therapeutic bone regeneration. W...

The Role of Bone Marrow Aspiration and Bone Marrow Biopsy in Diagnosis of Bone Marrow Metastases

Background: Bone marrow is the site of many malignant disorders and it is one of the common places for solid tumors to metastasize. Examination of the bone marrow aspirate and biopsy is a routine procedure performed for assessment of various conditions such as cytopenias, hematologic neoplasms, nonmalignant disorders and metastatic neoplasms. Methods: The patients were referred to the Hema...

Capillary Network Formation by Endothelial Cells Differentiated from Human Bone Marrow Mesenchymal Stem Cells

Human bone marrow derived mesenchymal stem cells (HBMSCs) have the potential to differentiate into cells such as adipocyte, osteocyte, hepatocyte and endothelial cells. In this study, the differentiation of hBMSCs into endothelial like-cells was induced in presence of vascular endothelial growth factor (VEGF) and insulin-like growth factor (IGF-1). The differentiated endothelial cells were exam...
