Figure 5. Ssbp2 depletion reduces the expression domain of proximal and distal tubule markers. 8-cell stage Xenopus embryos were injected into a single V2 blastomere as indicated. The uninjected contralateral side was used as an internal control. (ae) WISH for pax2 in stage 32 embryos. *Indicate the position of the nephrostomes. (a) Uninjected embryo (8% affected, n=37, N=3). (b, c) St-MO 15 ng injected embryo (23% affected, n=40, N=2). (d, e) ssbp2-MO 15 ng injected embryo (66% affected, n=51, N=3). (fj) WISH for slc5a1 in stage 39 embryos. (f) Uninjected embryo (4% affected, n=47, N=2). (g, h) St-MO 15 ng injected embryo (19% affected, n=39, N=2). (i, j) ssbp2-MO 15 ng injected embryo (50% affected, n=34, N=2). (ko) WISH for clcnkb in stage 39 embryos. (k) Uninjected embryo (3% affected, n=35, N=2). (l, m) St-MO 15 ng injected embryo (23% affected, n=41, N=2). (n, o) ssbp2-MO 15 ng injected embryo (49% affected, n=33, N=2). Magnifications of the pronephric tubules enclosed by the black squares are shown in the left-bottom corner. Statistical significance was evaluated using Chi-square test (****p<0.0001; **p<0.01). *, Represent the comparison to the uninjected and the St-MO injected groups, respectively. Representative embryos are shown. Image published in: Cervino AS et al. (2023) Copyright © 2023. Image reproduced with permission of the Publisher and the copyright holder.
