Previously we described a reliable method based on immunodepletion for isolating mesenchymal stem cells (MSCs) from murine bone marrow and showed that, after intracranial transplantation, the cells migrated throughout forebrain and cerebellum and adopted neural cell fates. Here we systemically administered MSCs purified by immunodepletion from male(More)
Mesenchymal stem cells (MSCs) transplanted at sites of nerve injury are thought to promote functional recovery by producing trophic factors that induce survival and regeneration of host neurons. To evaluate this phenomenon further, we quantified in human MSCs neurotrophin expression levels and their effects on neuronal cell survival and neuritogenesis.(More)
BACKGROUND Previously, we demonstrated that murine mesenchymal stem cells (MSCs) injected intracranially into mice expand throughout the central nervous system (CNS). This paper describes real-time PCR (RT-PCR) assays that enables accurate quantification of transplanted cells in vivo. METHODS RT-PCR assays that amplify sequences in the mouse Y chromosome(More)
Mesenchymal stem cells (MSCs) are typically enriched from bone marrow via isolation of the plastic adherent, fibroblastoid cell fraction. However, plastic adherent cultures elaborated from murine bone marrow are an admixture of fibroblastoid and hematopoietic cell types. Here we report a reliable method based on immunodepletion to fractionate fibroblastoid(More)
Mesenchymal stem cells (MSCs) have demonstrated efficacy as cellular vectors for treating a variety of nervous system disorders. Nevertheless, few studies have quantified MSC engraftment levels or explored the mechanisms that promote their survival and migration in nervous tissue. In this study, we compared the engraftment kinetics and anatomical(More)
Congenital neurodegenerative diseases exhibit progressive postnatal neurologic impairment leading to premature death and are intractable to systemic therapies such as bone marrow transplantation. We injected bone marrow-derived mesenchymal stem cells (MSCs) into the CNS of young adult rhesus macaques to evaluate their safety and feasibility as vectors for(More)
Mesenchymal stem cells (MSCs) have demonstrated efficacy as therapeutic vectors in rodent models of neurological diseases, but few studies have evaluated their safety and efficacy in a relevant large animal model. Previously, we reported that MSCs transplanted to the central nervous systems (CNS) of adult rhesus macaques engrafted at low levels without(More)
Craniomaxillofacial defects secondary to trauma, tumor resection, or congenital malformations are frequent unmet challenges, due to suboptimal alloplastic options and limited autologous tissues such as bone. Significant advances have been made in the application of adipose-derived stem/stromal cells (ASCs) in the pre-clinical and clinical settings as a cell(More)
