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.
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

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...
This study is a case-control prospective, clinal trial to assess the safety and efficacy of the allogeneic adipose derived mesenchymal stem cell transplantation on the healing of recent ti...
The purpose of this study is to determine the effect of low-intensity, pulsed ultrasound on tibial fractures treated with intramedullary nailing.
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...
Case series of tibial plateau fractures using Norian Drillable.
Ex vivo expansion of hematopoietic stem cells (HSCs) with most current methods can hardly satisfy clinical application requirement. While in vivo, HSCs efficiently self-renew in niche where they inter...
BACKGROUND Mesenchymal stromal cells, MSCs, show expression of specific antigens on their surface. The aim of the study is to assess the phenotype of stem cells like isolated from the umbilical cord w...
A human bone marrow-derived mesenchymal stromal cell (MSCs) and cord blood-derived CD34+ stem cell co-culture system was set up in order to evaluate the proliferative and differentiative effects induc...
We and others have reported that human hematopoietic stem cells (HSCs) are also present in the CD34-negative (CD34(-)) fraction of human cord blood (CB). Here, we examined the hematopoietic engraftmen...
Tibial plateau fractures are articular fractures that sometimes prove difficult to effectively manage and treat. Although fluoroscopy is frequently used to assess the articular reduction in the surgic...
A member of the prominin family, AC133 Antigen is a 5-transmembrane antigen occurring as several isoforms produced by alternative splicing which are processed into mature forms. In humans, it is expressed as a subset of CD34 (bright) human hematopoietic stem cells and CD34 positive leukemias. Functionally, it is associated with roles in cell differentiation, proliferation, and apoptosis. Specifically, it regulates the organization of apical plasma membrane in epithelial cells, disk morphogenesis during early retinal development, MAPK and Akt signaling pathways, and in cholesterol metabolism.
Fractures of the TIBIA.
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.

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.
Bone-marrow-derived, non-hematopoietic cells that support HEMATOPOETIC STEM CELLS. They have also been isolated from other organs and tissues such as UMBILICAL CORD BLOOD, umbilical vein subendothelium, and WHARTON JELLY. These cells are considered to be a source of multipotent stem cells because they include subpopulations of mesenchymal stem cells.
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
An anesthesiologist (US English) or anaesthetist (British English) is a physician trained in anesthesia and perioperative medicine. Anesthesiologists are physicians who provide medical care to patients in a wide variety of (usually acute) situations. ...
