Role for circulating osteogenic precursor cells in aortic valvular disease.
OBJECTIVE Approximately 13% of aortic valves removed from patients with end-stage aortic valve disease contain heterotopic ossification (HO). Recently, we identified a novel population of circulating osteogenic precursor (COP) cells that are derived from bone marrow and have the capability to form bone. These cells are identified by coexpression of the osteogenic marker type 1 collagen or osteo...
متن کاملMechanisms of Gravitational Sensitivity of Osteogenic Precursor Cells
This report is a detailed review of the current data on the mechanic and gravitational sensitivity of osteoblasts and osteogenic precursor cells in vitro. It summarizes the numerous responses of cells with an osteoblastic phenotype and osteogenic precursor cells and especially their responses to the alteration of their mechanic or gravitational surroundings. The review also discusses the osteog...
متن کاملOrigin of osteogenic precursor cells in extramedullary marrow implants.
Autologous extramedullary marrow imresistant and is therefore probably asplantation leads to the formation of a sociated with the relatively radioresistant nodule consisting of bone and hemopoiemarrow stroma. When the marrow was tic tissue. Irradiation of the marrow irradiated with 4000 rads 2 wk prior to immediately prior to implantation with implantation it did not regenerate even up to 1000 ...
متن کاملCirculating CD34-Positive Cells Promote Early Osteogenic differentiation of Human Fracture Hematoma-Derived Progenitor Cells in
INTRODUCTION Human circulating CD34+ cells, an endothelial progenitor cell (EPC)enriched population [1], have been also reported to differentiate into osteoblasts [2]. Previously, we demonstrated that that human circulating CD34+ cells, systemically transplanted into immunodeficient rats with nonhealing fracture, were recruited into fracture sites, contributed to a favorable environment for fra...
متن کاملMolecular mechanisms in dental follicle precursor cells during the osteogenic differentiation.
The discovery of dental stem cells received extensive attention because of its significance for the development of novel cellular therapies in dentistry. However, dental stem cells are also excellent for studies about cellular processes during dental tissue development or regeneration. Multipotent undifferentiated cells in the dental follicle (DFCs) are one example of dental stem cells. These c...
