(b) Mild tubular injury (CD133, 1+)

(c) Moderate tubular injury (CD133, 2+)

(d) Severe tubular injury (CD133, 3+)
Figure 2: CD133 expression in varying degrees of renal tubular injury. Under normal circumstances, only focal CD133 positive cells were noted in renal tubules (a). With injury, tubular expression of CD133 can demonstrate mild to severe upregulation (mild, (b); moderate, (c); severe, (d)) (magnification ×400, (a)–(d)).
