We assessed the combination of sirolimus and tacrolimus without methotrexate after myeloablative allogeneic stem cell transplantation from 53 matched related donors (MRDs) and 30 unrelated donors (URDs). All patients received cyclophosphamide and total body irradiation conditioning followed by transplantation of mobilized peripheral blood stem cells. The(More)
BACKGROUND Neuroblastomas are characterized by chromosomal alterations with biological and clinical significance. We analyzed paired blood and primary tumor samples from 22 children with high-risk neuroblastoma for loss of heterozygosity (LOH) and DNA copy number change using the Affymetrix 10K single nucleotide polymorphism (SNP) array. FINDINGS Multiple(More)
BACKGROUND Paclitaxel and docetaxel are active agents in advanced urothelial cancer. BMS-247550 (ixabepilone) has activity in preclinical models in paclitaxel resistant models. A phase 2 trial of this epothilone was performed to determine the activity and toxicity of this agent in a multi-institutional setting in patients previously treated with 1 prior(More)
PURPOSE To provide an update on long-term survival of patients with high-risk neuroblastoma treated with tandem cycles of myeloablative therapy and peripheral-blood stem-cell rescue (PBSCR). PATIENTS AND METHODS Ninety-seven patients with high-risk neuroblastoma were treated between 1994 and 2002. Patients underwent induction therapy with five cycles of(More)
The mammalian skull vault, a product of a unique and tightly regulated evolutionary process, in which components of disparate embryonic origin are integrated, is an elegant model with which to study osteoblast biology. Our laboratory has demonstrated that this distinct embryonic origin of frontal and parietal bones confer differences in embryonic and(More)
Although dura mater tissue is believed to have an important role in calvarial reossification in many in vivo studies, few studies have shown the direct effect of dura mater cells on osteoblasts. In addition, no reports have yet identified the potential factor(s) responsible for various biological activities exerted by dura mater on calvarial reossification(More)
Oral mucositis occurs in up to 75% of recipients of high-dose chemoradiotherapy conditioning regimens used for allogeneic hematopoietic stem cell transplantation (HSCT). As a result of mucositis, narcotic analgesia and total parenteral nutrition (TPN) are commonly required after HSCT. Methotrexate, an antiproliferative graft-versus-host disease (GVHD)(More)
BACKGROUND Stem cell-based bone tissue engineering with adipose-derived stromal cells (ASCs) has shown great promise for revolutionizing treatment of large bone deficits. However, there is still a lack of consensus on cell surface markers identifying osteoprogenitors. Fluorescence-activated cell sorting has identified a subpopulation of CD105(low) cells(More)
BACKGROUND High-dose thiotepa, busulfan, and cyclophosphamide (TBC) with autologous stem cell transplantation (ASCT) has been used in patients with central nervous system (CNS) involvement by non-Hodgkin lymphoma (NHL). Despite limited penetration into the CNS, rituximab is active in primary CNS NHL. Therefore, high-dose rituximab was combined with TBC for(More)
INTRODUCTION Hypoxia-inducible factor (HIF)-1α, part of the heterodimeric transcription factor that mediates the cellular response to hypoxia, is critical for the expression of multiple angiogenic growth factors, cell motility, and the recruitment of endothelial progenitor cells. Inhibition of the oxygen-dependent negative regulator of HIF-1α, prolyl(More)
