( D–K ) lhx1a whole-mount in situ hybridization (WISH) showing the trunk kidney region at 7 dpi. XAV939 ( F ) could reduce the number of lhx1a + cell aggregates and dmPGE2 could rescue the influence of XAV939 treatment ( G ); ICRT 14 ( H ) or ICG-001 ( J ) could reduce the number of lhx1a + cell aggregates and dmPGE2 could not rescue the influence of ICRT 14 ( I ) or ICG-001 ( K ) treatment. n = 5–7 in each condition. ( L ) lhx1a + cell aggregates of whole kidney were calculated using ImageJ. Data were analyzed by ANOVA, ***p<0.001; ns, no significant difference. ( M–V ) Immunofluorescence staining of β-catenin in Tg(lhx1a:DsRed ) zebrafish kidneys at 5 dpi. ( M, N ) Zebrafish injected DMSO as a control group, and the amount of β-catenin could be detected in lhx1a + cell aggregates during renal progenitor cell (RPC) aggregation ( M ) or proliferation ( N ). ( O ) β-catenin level in lhx1a + cell aggregates of cox2a -/- was significantly less than the control group, and injection of dmPGE2 ( P, Q ) could rescue the influence of Cox2a deficiency. ( R ) β-catenin level in lhx1a + cell aggregates of wnt4a -/- was significantly less than the control group, and injection of dmPGE2 ( S, T ) could rescue the influence of Wnt4a deficiency. Injection of PKI ( U ) could reduce β-catenin level in lhx1a + cell aggregates, while injection of dmPGE2 ( V ) could not rescue the influence of PKI treatment. n = 3–6 in ( M–V ). Scale bar in ( M–V ), 50 μm. ( W ) Bar chart depicting β-catenin levels following acute kidney injury (AKI) ( M–V ). Fluorescent intensities per unit area were measured at the lhx1a + RPC aggregates using ImageJ. β-catenin levels of lhx1a + RPCs during RPC aggregation normalized as 1.
