Description

Dental pulp is the soft live tissue inside a tooth. Dental pulp contains stem cells, known as Dental Pulp Stem Cells. The finest Dental Pulp Stem Cells are found in a baby teeth or milk teeth. The stem cells from the milk teeth are ‘mesenchymal’ type of cells. cells that have the ability to generate a wide variety of cell types like chondrocytes, osteoblasts and adipocytes. To isolate high-quality human dental pulp stem cells from accessible resources is an important goal for stem-cell research. In this study we found that exfoliated
human deciduous tooth contains multipotent stem cells, they identified to be a population of highly proliferative, clonogenic cells. Hematopoietic stem cells (HSCs) are the blood cells that give rise to all the other blood cells. HSCs are found in the bone marrow of adults, with large quantities in the pelvis, femur, and they are also found in umbilical cord blood and, in small numbers, in blood. In this study we differentiated stem cells that isolated from human dental pulp and peripheral blood to cardiac cells. The isolation process for
dental pulp stem cells would take place in 2 different methods: The enzymatic digestion method and, the second method is a subsidiary one. For isolating the stem cells from peripheral blood we use ficoll method. Flow cytometery analyzes showed that dental pulp stem cells are mesanchymal and peripheral blood cells are hematopoietic stem cells. Bothe group of stem cells can differentiation to cardiac cells. Dental pulp stem cells are mesanchymal cells and peripheral blood cells are hematopoietic cells. For differentiation the cells to cardiomyocite we used 5-azacitidin and exitocin. After differentiation stem cells to cardiac cells, dental pulp stem cells and peripheral blood stem cells morphology was changed, before differentiation to cardiac cells, both group were elongated and after differentiated to cardiomyocit they have central typical nuclear and were stratified ,they expanded cytoplasmic papillae .
