Mesenchymal stem cells (MSCs) are multipotent cells found in both fetal and adult tissues. MSCs show promise for cellular therapy for several disorders such as those associated with inflammation. In adults, MSCs primarily reside in the bone marrow (BM) and adipose tissues. In BM, MSCs are found at low frequency around blood vessels and trabecula. MSCs are attractive candidates for regenerative ...
Alterations in hematopoietic microenvironment of acute lymphoblastic leukemia patients have been claimed to occur, but little is known about the components of marrow stroma in these patients. In this study, we characterized mesenchymal stromal cells (MSCs) isolated from bone marrow (BM) of 45 pediatric patients with acute lymphoblastic leukemia (ALL-MSCs) at diagnosis (day+0) and during chemoth...
Cell-based therapies, using multipotent mesenchymal stem cells (MSCs) for organ regeneration, are being pursued for cardiac disease, orthopedic injuries and biomaterial fabrication. The molecular pathways that regulate MSC-mediated regeneration or enhance their therapeutic efficacy are, however, poorly understood. We compared MSCs isolated from MRL/MpJ mice, known to demonstrate enhanced regene...
Interferon-beta (IFN- β ), a well-established standard treatment for multiple sclerosis (MS), has proved to exhibit clinical efficacy. In this study, we first evaluated the therapeutic effects for MS using human bone marrow-derived mesenchymal stem cells (hBM-MSCs) as delivery vehicles with lesion-targeting capability and IFN- β as therapeutic gene. We also engineered hBM-MSCs to secret IFN- β ...
BACKGROUND Neurogenin2 (Ngn2) is a proneural gene that directs neuronal differentiation of progenitor cells during development. Here, we investigated whether Ngn2 can reprogram MSCs to adopt a neural precursor fate and enhance the therapeutic effects of MSCs after experimental stroke. METHODS In vitro, MSCs were transfected with lenti-GFP or lenti-Ngn2. Following neuronal induction, cells wer...
Bone marrow derived mesenchymal stromal cells (MSCs) have recently been implicated as one source of the tumor-associated stroma, which plays essential role in regulating tumor progression. In spite of the intensive research, the individual factors in MSCs controlling tumor progression have not been adequately defined. In the present study we have examined the role of galectin-1 (Gal-1), a prote...
Our previous study found that the activity of PCa-MSCs, which could stimulate the cell proliferation of RM-1, was significantly different compared to BMMSCs. Our results indicated that it could be mediated in part by growth factors/chemokines, which were involved in the different activity between two kinds of MSCs (PCa-MSCs and BMMSCs). Normal MSCs (BMMSCs) were isolated from the femur, tibia o...
BACKGROUND AND AIMS Mesenchymal stromal cells (MSCs) were shown to have immunomodulatory activity and have been applied for treating immune-mediated disorders. We compared the homing and therapeutic action of cryopreserved subcutaneous adipose tissue (AT-MSCs) and bone marrow-derived mesenchymal stromal cells (BM-MSCs) in rats with trinitrobenzene sulfonic acid (TNBS)-induced colitis. METHODS...
Objective: Umbilical cord Wharton’s jelly as source of mesenchymal stem cells (MSCs) can be easily obtained. In this study, MSCs were isolated from bone marrow and Wharton’s jelly and induced to differentiate into endothelial-like cells. Materials and Methods: MSCs were isolated and induced to differentiate into endothelial-like cells using vascular endothelial growth factor (VEGF). The endothe...
Interferon- –stimulated marrow stromal cells: a new type of nonhematopoietic antigen-presenting cell
Several studies have demonstrated that marrow stromal cells (MSCs) can suppress allogeneic T-cell responses. However, the effect of MSCs on syngeneic immune responses has been largely overlooked. We describe here that primary MSCs derived from C57BL/6micebehaveasconditionalantigenpresenting cells (APCs) and can induce antigen-specific protective immunity. Interferon gamma (IFN )–treated C57BL/6...
