The Low-Affinity Nerve Growth Factor Receptor (LNGFR), also known as CD271, is a member of the tumor necrosis factor receptor superfamily. The CD271 cell surface marker defines a subset of multipotential mesenchymal stromal cells and may be used to isolate and enrich cells derived from bone marrow aspirate. In this study, we compare the proliferative and differentiation potentials of CD271+ and...

Multiple myeloma is an incurable hematologic cancer characterized by the clonal proliferation of malignant plasma cells within the bone marrow. Numerous studies suggest that the myeloma plasma cells occupy and alter the stromal tissue of the bone marrow as a means of enhancing their survival and growth. However, the nature and magnitude of the changes to the stromal cell tissue remain to be det...

Multipotent mesenchymal stromal cells or mesenchymal stem cells (MSCs) are mainly isolated from bone marrow or fat tissue. Because of their potential of multilineage differentiation towards bone, cartilage and fat tissue, they were initially evaluated to develop innovative strategies for tissue engineering applications. More recently, they have gained interest based on their immunomodulatory pr...

BACKGROUND Application of autologous bone marrow mononuclear cells to "no option" patients with advanced critical limb ischemia (CLI) prevented major limb amputation in 73% patients during the 6-month follow-up. We examined which properties of bone marrow stromal cells also known as bone-marrow derived mesenchymal stem cells of responding and non-responding patients are important for amputation...

The bone marrow is a complex environment that houses haematopoietic and mesenchymal cell populations and regulates bone turnover throughout life. The high proliferative capacity of these cell populations however, makes them susceptible to damage and injury, altering the steady-state of the bone marrow environment. Following cancer chemotherapy, irradiation and long-term glucocorticoid use, redu...

Previous studies have provided evidence for the existence of adult human bone marrow stromal stem cells (BMSSCs) or mesenchymal stem cells. Using a combination of cell separation techniques, we have isolated an almost homogeneous population of BMSSCs from adult human bone marrow. Lacking phenotypic characteristics of leukocytes and mature stromal elements, BMSSCs are non-cycling and constitutiv...

objective: non:union: is defined as a minimum of a 9-month period of time since an injury with no visibly progressive signs of healing for 3 months. recent studies show that application of mesenchymal stromal cells (mscs) in the laboratory setting is effective for bone regeneration. animal studies have shown that mscs can be used to treat non:union:s. for the first time in an iranian population...

Amyotrophic Lateral Sclerosis (ALS) is a terminal neurodegenerative disease with only few minimally effective treatment options. This study treats patient Spinal ALS Bone Marrow Derived Mesenchymal Stem Cell Extracellular Vesicles (BM-MSCEVs) to slow or stop the progress of disease. After 2 months and 4 treatments, demonstrated improvement in functional scores most physical exam findings. BM-MS...

Osteoporosis (OP) is characterized by a decrease in osteoblasts and an increase adipocytes the bone marrow compartment, alongside abnormal bone/fat differentiation, which ultimately results imbalanced homeostasis. Bone mesenchymal stem cells (BMSCs) can differentiate into to maintain Several studies have shown that lncRNAs are competitive endogenous RNAs form lncRNA–miRNA network targeting miRN...

Osteoblasts and adipocytes share a common mesenchymal progenitor in the bone marrow. This implies that a reciprocal relationship exists between osteogenic and adipogenic differentiation. Further, cells of osteoblast lineage transdifferentiate into adipocytes under some circumstances. Dysregulation of osteo-adipogenic fate-determination leads to bone diseases such as osteoporosis, accompanied by...
