Various in vitro preconditioning strategies have been implemented to increase the regenerative capacity of MSCs. Among them are modulation culture atmosphere (hypoxia or anoxia), three-dimensional (3D), addition trophic factors (in form growth factors, cytokines hormones), lipopolysaccharides, and pharmacological agents. Preconditioning mesenchymal stem cells by culturing a hypoxic environment,...
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...
Background and Objective: Adipose tissue-derived stem cells (ADSCs) are very similar in their cell properties to bone marrow stromal cells (BMSCs) and can be a suitable alternative for cell therapy trials. The purpose of this study is comparison of adipose-derived stem cells (ADSCs) and bone marrow stromal cells (BMSCs) in prolonged passages based on viability and auto-differentiation tow...
Cancer stem cells (CSC) are predicted to be critical drivers of tumor progression due to their self-renewal capacity and limitless proliferative potential. An emerging area of research suggests that CSC may also support tumor progression by promoting tumor angiogenesis. To investigate how CSC contribute to tumor vascular development, we used an approach comparing tumor xenografts of the C6 glio...
Tendon never restores the complete biological and mechanical properties after healing. Bone marrow and recently adipose tissue have been used as the sources of mesenchymal stem cells, which have been proven to enhance tendon healing. Stromal vascular fraction (SVF), derived from adipose tissue by an enzymatic digestion, represents an alternative source of multipotent cells, which undergo differ...
Platelets play roles in both thrombosis and inflammation, and chemokines that are released at sites of inflammation could potentially activate platelets. Among the chemokine receptors expressed on platelets, the CXCR4 is the receptor for chemokine stromal cell-derived factor-1 (SDF-1), and the CCR4 is the receptor for macrophage-derived chemokine (MDC). Of the chemokines tested, SDF-1 and MDC w...
Tumors are highly complex tissues composed of neoplastic cells and, in the case of carcinomas, stromal cell compartments containing a variety of mesenchymal cells, notably fibroblasts, myofibroblasts, endothelial cells, pericytes, and a variety of inflammatory cells associated with the immune system. Fibroblasts and myofibroblasts often represent the majority of the stromal cells within various...
