background cleft palate (cp) is a common congenital defect. it makes serious difficulties for cleft-affected children. the gold standard of care is autogenous bone grafting which may cause additional problems in donor site along with disappointing results. tissue engineering is a promising solution for a widespread range of defects and disorders. it is reasonable to utilize this novel technolog...

background: mesenchymal stem cells (mscs) are multipotent cells, capable of differentiating into different cell lines.they can sense their surrounding biochemical and biophysical factors, which play major roles in their differentiation toward different phenotypes. therefore, the exposure of these cells to endothelial growth factor (vegf) as well as hemodynamic biomechanical forces, which act on...

the ability to culture human stem cells long term, and possibly indefinitely, and to control how such cells specialise to form the different tissues of the body offers the possibility of major advances in healthcare. stem cells have been isolated and cultured, but a great deal of research is required to develop cell lines which can generate replacement cells and tissues to treat many diseases.s...

stem/progenitor cell based therapeutic approach in our daily routine clinical practice, has been elusive dream in medical sciences and improvement of stem cell homing as one of major challenges in cell therapy programs, has been considered a promising milestone. it has been proved that stem/progenitor cells exhibit a homing response to injured tissues/organs, mediated by interactions of chemoki...

introduction: we aimed at evaluating the clinical, laboratory and echocardiography effects of intracoronary administration of autologous bone marrow stem cell transplantation in different clinical entities of chronic heart failure (hf) patients.   methods: this procedure was carried out during an interventional study conducted in the cardiology department from jan 2012 to apr 2013. the hf patie...

introduction: mesenchymal stem cells can be isolated from adult tissues, such as the adipose tissue, or other sources. among all these sources, adipose tissue because of easy access, and placenta due to its immunomodulatory properties, in addition to another useful properties, were attracted more attention to themselves. isolation and comparing these two different sources can help us for access...

introduction  insulin-like growth factor i (igf-i) which is produced in abundance in the normal adult liver, is deeply involved in hepatocyte survival, growth, and differentiation during liver development. igf-i plays the roles via the receptor (igf-ir) signaling pathway. igf-ir unlike igf-i is expressed strongly in the developing liver, but much more weakly in adults. objective:  we hypothesiz...

background  the mammary gland in humans is a dynamic organ that undergoes significant developmental changes during pregnancy, lactation, and involution. stem cells derived from human breast milk possess the adult stem cell-like characteristics such as self-renewal, proliferative and differentiate potential. this source of stem cells avoids invasive procedures and the ethical controversy of embr...

background  multiple procedures (lumbar puncture and bone marrow aspiration /biopsy) cause pain, stress, depression and etc for the patients and their families. various methods have been recommended for pain reduction during invasive procedures. the aim of this study is to report the complications following general anesthesia. methods in this prospective observational study, two hundred and two...
