Background: Stem cell therapy has been developed as an effective treatment method for the heart failure. Also, extracellular matrix has shown the positive effects in stem cell differentiation and myocardial tissue organization. Cardiogel is a native cardiac extracellular matrix (ECM) derived from cardiac fibroblasts. In the present study the role of cardiogel is examin...
Background and Objective: Bone marrow stromal cells (BMSCs) have been shown to be a feasible option for cell therapy. There is increasing evidence that BMSCs have the potential of differentiation into GABAergic like neuron cells (GLNCs) in vitro under appropriate induction protocols. GABAergic dysfunction is implicated in several neurological disorders. The present study provides eviden...
The extract of pluripotent stem cells induces dedifferentiation of somatic cells with restricted plasticity. In this study, we used the extract of human embryonic stem cells (hESC) to dedifferentiate adipose tissue-derived stem cells (ADSCs) and examined the impact of this reprogramming event on dopaminergic differentiation of the cells. For this purpose, cytoplasmic extract of ESCs was prepare...
Stem cells are a good alternative for regenerative medicine because of their characteristics such as self-renewal and differentiation potential. They are classified into different types of stem cells including embryonic stem cells, induced pluripotent stem cells, multipotent stem cells, and ultimately uni-potent stem cells. Mesenchymal stem cells extracted from adult tissues. Due to the lack of...
Stem cells are undifferentiated precursor cells with the capacity for proliferation or terminal differentiation. Progression down the differentiation cascade results in a loss of proliferative potential in exchange for the differentiated phenotype. This balance is tightly regulated in the physiologic state. Recent studies, however, have demonstrated that during tumorigenesis, disruptions preven...
The therapeutic potential of differentiation therapy for glioblastoma will depend on the robustness and stability of the differentiated state. We recently reported several obstacles to bone morphogenetic protein (BMP)-induced differentiation therapy. Improved understanding of the mechanisms that tumor cells use to escape differentiation commitment is urgently needed.
Genetic and epigenetic events within a cell which promote a block in normal development or differentiation coupled with unregulated proliferation are hallmarks of neoplastic transformation. Differentiation therapy involves the use of agents with the ability to induce differentiation in cells that have lost this ability, i.e. cancer cells. The promise of differentiation-based therapy as a viable...
background: in the field of cellular therapy, the impact of confluence degree to harvest or differentiate bmmscs and the effect of cell-to-cell contact remains controversial. therefore, the effect of confluence on bmmscs properties was studied and confluence-associated osteogenic differentiation efficiency was identified. materials and methods: the impact of confluences at 20, 50, 70, 80 and 10...
introduction: different effects of low level laser irradiation (llli) on various cell types have already been demonstrated. however, its effects on embryonic stem cells have not yet been shown. the present study evaluates the morphological and immunocytochemical effects of llli on human embryonic stem cell (hesc) colonies. material and methods: equal-sized pieces of hesc line (royan h1) were ir...
