chronic myeloid leukemia (cml) is a myeloproliferative disease of the hematopoietic stem cells, characterized by the presence of the philadelphia (ph) chromosome. although imatinib inhibits the bcr-abl kinase activity, clinical experiences confirm that imatinib may not target cml stem cells in vivo. the identification of signaling pathways responsible for the self-renewal properties of leukemic...

background: mesenchymal stem cells (mscs) are important candidates for msc-based cellular therapy. current paradigm states that mscs support local progenitor cells in damaged tissue through paracrine signaling. therefore, study of paracrine effects and secretome of mscs could lead to the appreciation of mechanisms and molecules associated with the therapeutic effects of these cells. this study ...

Mesenchymal Stem Cell (MSC) therapy in osteoarthritis has been hailed as a promising treatment for osteoarthritis dueto their unlimited potential of healing and regeneration. Existing literature regarding their proper name, optimal sources,mechanisms of action, dosage, and route of administration, efficacy, and safety is debatable.
