Blastema formation is the key process in appendage regeneration. The underlying mechanism that support this process may help us understand what we missed for a concise regeneration. In the zebrafish caudal fin model, independent observations show that the blastema is contributed by both dedifferentiation of adult lineage cells and proliferation of resident progenitors. However, due to resolution limitations, the path of cell-state transition for these cells have not been clearly revealed. The two cell sources may share part of their path during regeneration, with adult lineage cells contributing to the progenitor population. To determine whether adult lineage cells join regeneration via dedifferentiating into a progenitor-like phase, I propose to track the cell-state of blastemal cells during regeneration by single-cell-RNA sequencing. Measurement and comparison of transcriptome in adult lineage cells and the progenitors at single-cell resolution may shed light on how each lineage respond and react during regeneration.
