Amniotic-Fluid Stem Cells: Growth Dynamics and Differentiation Potential after a CD-117-Based Selection Procedure
Figure 2
Morphological analysis of CD117+ and CD117– AF cells. (a) CD117+ cells reveal the typical elongated morphology of mesenchymal stem cells, (b) CD117− AF cells display a rather polymorph appearance of epithelial cells in vitro, inset, CD117− cells can be stained by the epithelial marker cytokeratin (red fluorescence) in a counterstain with the nuclear marker Hoechst dye (blue), scale bar in a and b = 25 μm, and in the inset in b = 15 μm.
