The number of GFP+ cells in the ablated area increases after ablation. (A) Timeline of the experiments. After ablation at 13?dpf, larvae were cultured and fixed at 1, 5 and 10?dpa for immunostaining. (B-D) Posterior intestines stained for GFP at 1?dpa (B) 5 dpa (C), and 10?dpa (D). The arrows and enclosed areas indicate the one-somite-width of intestine used for counting the GFP+ cells in the ablated area (magenta; ablated) and unablated (blue; internal control) area of the same larva at the second- and the fifth-somite level, respectively (see Materials and Methods for details). Images are left side views of the mid-distal intestines, with the anterior end positioned to the left of the image. Scale bar: 50?µm. (E) Number of GFP+ cells in ablated and internal control areas at 1, 5 and 10?dpa. Filled symbols indicate the numbers in individual larvae, and outline symbols indicate the meanħs.e.m. In the ablated areas, the number of GFP+ cells increased and reached ?50% of the control level within 10?days, whereas a significant change in the number of cells was not observed in the control area during the same period (1?dpa versus 10?dpa; two-tailed unpaired t-test, P=0.2). |
