Stem Cells and Tibial Fractures
The aim of this trial is to determine the safety and tolerability of expanded autologous progeny of an adult CD34+ (haemopoietic) stem cell subset when infused directly into the tibial artery of patients with recent tibial fracture. The trial will also seek to determine clinical improvement or deterioration by measurement of clinical parameters such as, length of time to union of the fracture, changes in bone mineral density, improvements in pain scores (VAS), functional ability (TUGT) and IPAQ scores.

Medical and Biotech [MESH] Definitions
Multipotent Stem Cells
Specialized stem cells that are committed to give rise to cells that have a particular function; examples are MYOBLASTS; MYELOID PROGENITOR CELLS; and skin stem cells. (Stem Cells: A Primer [Internet]. Bethesda (MD): National Institutes of Health (US); 2000 May [cited 2002 Apr 5]. Available from: http://www.nih.gov/news/stemcell/primer.htm)
Glycoproteins found on immature hematopoietic cells and endothelial cells. They are the only molecules to date whose expression within the blood system is restricted to a small number of progenitor cells in the bone marrow.
Peripheral Blood Stem Cell Transplantation
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
Embryonal Carcinoma Stem Cells
The malignant stem cells of TERATOCARCINOMAS, which resemble pluripotent stem cells of the BLASTOCYST INNER CELL MASS. The EC cells can be grown in vitro, and experimentally induced to differentiate. They are used as a model system for studying early embryonic cell differentiation.
Mesenchymal stem cells are found in bone marrow, and have the ability to differentiate into different tissue types. The primary objective of the study is to examine the safety of using suc...
The purpose of this study is to determine the effect of low-intensity, pulsed ultrasound on tibial fractures treated with intramedullary nailing.
Case series of tibial plateau fractures using Norian Drillable.
This is a prospective dose escalation study of the administration of adult human stem cells in patients with end stage liver failure. Successive groups of two patients will receive ascendi...
The objective of the study is to determine the efficacy of brain transplants of CD34+ stem cells obtained from peripheral blood of patients in the treatment of chronic stroke patients.
In this study, we employed bio-derived bone scaffold and composited with the marrow mesenchymal stem cell induced into osteoblast to replicate a "biomimetic niche." The CD34(+) cells or mononuclear ce...
Accurate intra-operative reduction and maintenance of reduction is essential for successful fixation of tibial fractures. Although many tibial fractures can be reduced with minimal manipulation, numer...
BACKGROUND: Segmental tibial fractures are considered to be a special injury type associated with high complication rates. However, it is unclear whether healing of these fractures truly differs from...
Much controversy surrounds the identity and origin of human hepatic stem and progenitor cells in part because of a lack of small animal models in which the developmental potential of isolated candidat...
Peripheral blood stem cell cryopreservation is associated with cell damage and decreased viability. We evaluated the impact of up to 10 years of cryopreservation (5% DMSO) on viability of CD34(+) cel...
