Geometric and unipotent crystals. It is currently unclear if true unipotent stem cells exist. Multipotent stem cells such as mesenchymal stem cells (MSCs) can engraft and differentiate into new cardiomyocytes (Quevedo et al., 2009), although there are conflicting results as to degree to which these cells actually differentiate and the maturity of the new cardiomyocytes, and this mechanism may play only a limited role in the therapeutic capacity of these cells in . Unipotent cells are adult cells that can only differentiate into their own lineage. • Unipotent cells can produce only one cell type, their own, but have the property of self-renewal, which distinguishes them from non-stem cells. In contrast, tagged clusters of cells showing evidence of unipotent differentiation were composed of cells with the morphological appearance of basal cells. Cells capable of forming any cell type found in the body, but NOT capable at becoming an entirely new organism. Question 1 of 7 The self-renewal is the capacity of the stem cells to divide indefinitely, producing unaltered cell daughters maintaining the same properties of the progenitor cell.
