Currently, there are several techniques for the rehabilitation of atrophic maxillary ridges in literature. The grafting procedure using autogenous bone is considered ideal by many researchers, as it shows osteogenic capability and causes no antigenic reaction. However, this type of bone graft has some shortcomings, mainly the restricted availability of donor sites. In recent years, several alte...

Adipose tissue derived stem cells (ASCs) based therapies for the repair and regeneration of various tissues have been widely investigated recently because of their multilineage potential and self-renewal capability. Our previous study demonstrated that autologous ASCs loaded onto natural coral scaffolds could repair cranial critical-sized defects (CSDs) in a canine model. The objective of this ...

reconstruction methods are an essential prerequisite for functional rehabilitation of the stomatognathic system. plasma rich in growth factors (prgf) offers a new and potentially useful adjunct to bone substitute materials in bone reconstructive surgery. this study was carried out to investigate the influence of prgf and fibrin membrane on regeneration of bony defects with and without deprotein...

Recombinant G-CSF has been given to over 150 normal donors for the collection of allogeneic or syngeneic peripheral blood stem cells (PBSC). G-CSF was found to be well-tolerated with mild-moderate bone pain, edema and mild thrombocytopenia being the observed side effects. To date, approximately 90 unmodified primary PBSC transplants from HLA-identical related donors have been performed with eng...

Natural killer (NK)-cell alloreactivity is exploited in bone marrow transplantation to improve clinical outcome. Likewise, in solid organ transplantation, it has been recently shown that recipient NK cells may limit alloreactive T-cell responses through their capacity to prevent the persistence of graft-derived allogeneic dendritic cells (DCs). In a model of CD4(+) T cell-mediated allogeneic sk...

Graft Versus Host Disease (GVHD) is a life threatening complication of allogeneic bone marrow transplantation (BMT), an important therapy for a number of hematologic diseases. In its acute phase, GVHD involves activation of proinflammatory cytokine cascades and immune effector cells that result in target tissue damage (1, 2). Multiple cellular populations and cytokines interact in a complex pro...

Intestinal crypt cell apoptosis may occur after allogeneic bone marrow transplantation without clinically overt graft-versus-host disease. We describe this phenomenon in a case of a 12-year-old girl who had segments of the ileum resected because of a relapse of acute lymphoblastic leukemia. The diagnostic difficulties are discussed.

various biological bone g rafts have been used for osteogenes i s , osteoconduction and even osteoinduction, but due to systemic influences and local factors, the outcome of successful incorporation of a bone graft has not been satisfactory. this study was therefore conducted on 15 clinically healthy adult dogs between 1 to 3 years of age weighing 20 to 30 kg to evaluate the effect of bone ceme...

Bone marrow fibrosis is a hallmark of primary and post ET/PV myelofibrosis. To investigated the impact of replacement of the hematopoietic system in myelofibrosis patients by allogeneic stem cell transplantation on bone marrow fibrosis, we studied bone marrow fibrosis on bone marrow samples from 24 patients with myelofibrosis before and after dose-reduced conditioning followed by allogeneic ste...
