Reduced population of Otp+ progenitors in the TPp of pink1-/- zebrafish at 3 months and 24 months of age. (A) Quantification of the number of Otp+Th1- progenitors and the number of Otp+Th1+ DA neurons in the TPp at 3 months shows a significant reduction in the number of Otp+Th1- progenitors in the pink1-/- zebrafish compared to pink1+/+ zebrafish (t-test, p = 0.0292, n = 2 fish for each), but no significant difference in the number of Otp+Th1+ DA neurons. (B) Quantification of the number of Otp+Th1- progenitors and the number of Otp+Th1+ DA neurons in the TPp at 24 months shows a significant reduction in the number of Otp+Th1- progenitors in the pink1-/- zebrafish compared to pink1+/+ zebrafish (t-test, p = 0.0259, n = 4 fish for each), and in the number of Otp+Th1+ DA neurons (t-test, p = 0.0453, n = 4 fish for each).
