Bone marrow transplantation (BMT) to treat severe hematologic malignancies often leads to potentially fatal acute graft-versus-host disease (GVHD), despite attempts at better donor-recipient matching and/or use of immunosuppressive agents. We report that embryo-derived PreImplantation Factor (PIF) plays a determining role in developing maternal/host(More)
INTRODUCTION Embryo-derived PIF modulates systemic maternal immunity without suppression. Synthetic analog (sPIF) prevents juvenile diabetes, preserves islet function, reducing oxidative stress/protein misfolding. We investigate sPIF effectiveness in controlling neuroinflammation/MS. METHODS Examine sPIF-induced protection against harsh, clinical-relevant(More)
BACKGROUND Mesenchymal stem cells (MSCs) have been demonstrated to potentially undergo chondrogenic differentiation. We propose a new matrix for stem cell-based chondrogenesis using dense fibrin microbeads (FMBs) combined with grounded dehydrothermally crosslinked collagen sponges (micronized collagen). METHODS In this study, MSCs were isolated from bone(More)
Over the past decade there has been a growing interest in using mesenchymal stem cells (MSCs) as an immune-regulatory agent for prevention and treatment of various immune disorders including graft-versus-host disease (GVHD), transplanted organ rejection, and autoimmune diseases. However, the high diversity in the results from clinical trials using MSCs for(More)
Acute Radiation Syndrome (ARS) may lead to cancer and death and has few effective countermeasures. Efficacy of synthetic PIF treatment was demonstrated in preclinical autoimmune and transplantation models. PIF protected against inflammation and mortality following lethal irradiation in allogeneic bone marrow transplant (BMT) model. Herein, we demonstrate(More)
