stem cell based treatments are being increasingly explored for their possible potential to treat various cancers. mesenchymal stem cells believed to possess anti-tumor potential and are preferred for their properties like immune privileged nature, ability to migrate to the site of tumor and capability for multilineage differentiation. this tumor tropism property of mscs could be utilized to del...

OBJECTIVE We sought to identify and characterize 2 distinct populations of bona fide circulating endothelial cells, including the endothelial colony-forming cell (ECFC), by polychromatic flow cytometry (PFC), colony assays, immunomagnetic selection, and electron microscopy. METHODS AND RESULTS Mononuclear cells from human umbilical cord blood and peripheral blood were analyzed using our recen...

BACKGROUND Bronchopulmonary dysplasia (BPD) presents a major threat of very preterm birth and treatment options are still limited. Stem cells from different sources have been used successfully in experimental BPD, induced by postnatal hyperoxia. OBJECTIVES We investigated the effect of umbilical cord blood mononuclear cells (MNCs) in a new double-hit mouse model of BPD. METHODS For the doub...

Umbilical cord blood (UCB) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (HSCs). Because of insufficient number of cord blood CD34+ cells, the expansion of these cells seems to be important for clinical application. Mesenchymal stromal cells (MSCs), playing an important role in HSCs maintenance, were used as feeder layer. Apo...

Cell Therapy For Therapeutic Vascularization Endothelial Progenitor Cells and Postnatal Vasculogenesis: Experimental Evidence The option of performing full-scale endothelial cell transplantation to optimize local neovascularization is daunting if even feasible. An alternative, attractive strategy is designed to exploit the conceptual notion that endothelial cells and hematopoietic stem cells we...

BACKGROUND Wound healing is a complex and dynamic process following damage in tissue structures. Due to extensive skin damage caused by burn injuries, this study determined the role of human adult peripheral and umbilical cord blood platelet-rich plasma on proliferation and migration in human skin fibroblasts. METHODS Platelet-rich plasma (5, 10, 15, 20 and 50% PRP) from human umbilical cord ...

Status epilepticus (SE) is a condition of persistent seizure that leads to brain damage and, frequently, to the establishment of chronic epilepsy. Cord blood is an important source of adult stem cells for the treatment of neurological disorders. The present study aimed to evaluate the effects of human umbilical cord blood mononuclear cells (HUCBC) transplanted into rats after induction of SE by...

background , despite numerous studies over a decade, it still remains controversial about the biological effects of rf emf emitted by mobile phone telephony. objective , here we investigated the effect of 900 mhz gsm on the induction of oxidative stress and the level of intracellular reactive oxygen species (ros) in human mononuclear cells, monocytes and lymphocytes as defence system cells. met...
