Figure 2In situ hybridization of α-SMA, Snail, and TGF-β1. (
a–
d) De novo expression of Snail (
a) and α-SMA (
c) mRNA in the renal tubular epithelial cells of WT mice at day 7 after UUO. There are no positive signals for Snail (
b) or α-SMA (
d) mRNA in Smad3-null (KO) counterparts. (
e and
f) Signals for TGF-β1 mRNA in WT (
e) and KO (
f) mice at day 14 after UUO. Insets, negative controls reacted with sense probe. Counterstained in nuclear fast red solution. Scale bars: 20 μm. Similar results were obtained from three additional experiments.
