Stem cell Cellular division Stem cell Differentiation Red blood cell Cellular division Stem cell Differentiation Red blood cell FIGURE 22.8 Growth pattern of stem celks. The two main traits that stem cells exhibit are an ability to divide and an ability to differentiate. When a stem cell divides, one of the two cells remains a stem cell, and the other daughter cell differentiates into a specialized cell type.
