OBJECTIVES Exosomes, a type of membrane vesicles, released from tumor cells have been shown to be capable of transferring tumor antigens to dendritic cells and activating specific cytotoxic T-lymphocytes. Recent work has demonstrated the presence of high numbers of exosomes in malignant effusions. Umbilical cord blood (UCB) is a rich source of hematopoietic stem cells and from which a significa...
Background: The use of random flaps is one of the most common methods of reconstructive surgery because they are easy to use and quick to do. However, the absence of axial vessels especially in the distal areas can cause ischemia and loss of total or part of the flap. Different methods and systemic and topical medications have been recommended to prevent ischemia in random flaps. The aim of thi...
Cell transplantation is a promising experimental treatment for spinal cord injury. The aim of the present study was to evaluate the efficacy of mononuclear cells from human umbilical cord blood in promoting functional recovery when transplanted after a contusion spinal cord injury. Female Wistar rats (12 weeks old) were submitted to spinal injury with a MASCIS impactor and divided into 4 groups...
Introduction: Recognition of human leukocyte antigens (HLA) is of importance for hematopoietic stem cell transplantation. Any HLA-mismatches between the donor and recipient can cause graft rejection or other complications. In HLA-typing experiments, usage of HLA-known reference cells accompany with HLA-unknown samples is obligatory. Some international centers represent these cells with high e...
heart failure is one of the leading causes of death worldwide. end stage disease often requires heart transplantation, which is hampered by donor organ shortage. tissue engineering represents a promising alternative approach for cardiac repair. for the generation of artificial heart muscle tissue several cell types, scaffold materials and bioreactor designs are under investigation. in this revi...
