Impaired Regeneration in Foxp3a-Deficient Zebrafish
(A) Foxp3a domain structure and predicted truncated product of the Foxp3avcc6 allele. Numbers indicate amino acid positions.
(B) Sections of Foxp3a-deficient (foxp3a−/−) and WT (foxp3a+/+) clutch-mate foxp3a:RFP fish. Asterisks indicate injury epicenter.
(C–E) Proliferation of newborn neurons (C), cardiomyocytes (D), and Müller glia (E). Insets show single-channel confocal slices (C and E) or epifluorescent images (D) of the demarcated regions. Arrows mark co-labeled cells. Dotted lines indicate the wound border.
(F–H) Quantification of (C), (D) and (E), respectively (mean ± SEM, n = 5–7).
(I–K) qRT-PCR analysis of regeneration factor genes (mean ± SEM, n = 6).
(L–N) Semi-qRT-PCR analysis of regeneration factor genes in purified foxp3a:RFP+ cells. +/+, foxp3a+/+; −/−, foxp3a−/−.
Confocal projections of z stacks are shown, except for the epifluorescent images in (D). ∗p < 0.05, ∗∗p < 0.01, Mann-Whitney U test. Scale bars, 50 μm. See also Figure S7.
