Figure 1Smad3-null mice maintain the renal architecture after UUO and have reversed EMT. (
a) Obstructed kidneys from WT and Smad3-null (KO) mice at day 14 after UUO. (
b and
c) Hematoxylin and eosin staining of the obstructed kidneys at day 14 after UUO in WT (
b) and KO (
c) mice. Scale bars: 20 μm. (
d–
g) Dual immunofluorescence of E-cadherin (green) and α-SMA (red) in obstructed kidneys of WT (
d and
e) and KO (
f and
g) mice at day 7 (
d and
f) and day 14 (
e and
g) after UUO. DAPI (blue) was used for nuclear staining. Scale bars: 20 μm. (
h) Immunoblot of E-cadherin (E-cad) and α-SMA with extracted proteins from kidneys of WT and KO mice with UUO and sham-operated WT mice (Sham). (
