Early process of the RE formation before 24 hpa.

(A) Experimental procedure for the fate analysis of epidermal cells that were pre-labelled by the Cre-loxP recombination in the Tg(fn1b:creERt2;Olactb:loxP-dsred2-loxP-egfp). The fn1b⁺ RE cells were labelled between 2 to 5 dpa. At 7 dpa, their fins were re-amputated and observed every 3 hrs until 24 hpa. (B) Representative fates of pre-labelled epidermal cells that locate in the inter-ray region (top and middle) and the ray region (bottom), respectively. Clusters of EGFP⁺ cells were chosen and tracked their fates. The inter-ray epidermal cells either migrated to become the ray RE (top) or kept staying in the inter-ray region (middle). All of the ray epidermal cells did not migrate laterally, contributing to the ray RE.
