Effects of hAFSCs and MSCs on Renal Morphology and Tubular Apoptosis

	Control	AKI + hAFSCs	AKI + MSCs	AKI
Casts (n/hpf)	0	0.36 ± 1.01*	0.54 ± 0.17†	5.05 ± 7.54
Necrosis (n/hpf)	0	0.81 ± 1.38*	0.3 ± 0.14†	3.85 ± 4.44
TUNEL-positive cells (n/hpf)	0	3.2 ± 0.8*	7.8 ± 2.2†	21.7 ± 16.9

Comparison of hAFSC or MSC injection on tubular morphology and apoptosis at day 5 after AKI induction. Numbers in the table represent the mean ± SD of tubular casts and necrotic tubules and of apoptotic cells detected by TUNEL, observed under high power (magnification, ×400).

^*P < 0.05 for hAFSC injection versus untreated AKI.

^†P < 0.05 for MSC injection versus untreated AKI.
