Despite the popularity of mesenchymal stem cells (MSCs), many fundamental aspects their physiology still have not been understood. The information accumulated to date argues that MSCs from different sources vary in differentiation potential and, probably, molecular mechanisms trilineage differentiation. Therefore, this review consists two parts. Firstly, we focus on data inter- and intra-source...

introduction:   mesenchymal stem cells have the potential of self-renewal and differentiation into different cell types, including blood cells, heart, nerves and cartilage, and have unlimited power for division. these cells can be obtained from cord, before implantation from fertilized cells and also from various tissues of adults although the differentiation power and the ability to reproduce ...

background: some antidepressant drugs can promote neuronal cell proliferation in vitro as well as hippocampal neurogenesis in human and animal models. furthermore, adipose tissue is an available source of adult stem cells with the ability to differentiate in to multiple lineages. therefore, human adipose-derived stem cells (hadscs) may be a suitable source for regenerative medical applications....

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...

Cell differentiation is a coordinated process that includes cell cycle exit and the expression of unique genes to specify tissue identity. The focus of this review is the recent progress in understanding the functions of the RB family (RB, p130,p107) in cell differentiation. Much work has focused on the functions of RB in G1 regulation. However, much evidence now suggests a diverse function in ...
