However  the regenerative mechanisms during periods of growth in young animals remain unexplored. Here  we establish two new partial liver injury protocols in the zebrafish model of rapid growth during late larval stage and observe emergence of de novo hepatocytes in the presence of spared hepatocytes. Using single cell RNA sequencing and lineage tracing  we identify cholangiocytes as the source of de novo hepatocytes. Our study offers a new perspective on the current paradigm of liver regenerating by proposing cholangiocyte to hepatocyte transdifferentiation as the default mechanism of hepatocyte recovery in late larval stage zebrafish.

Briefly  the liver was dissociated into single cells by incubation it in TrypLE Thermo Fisher  12563029 at 37\u00b0C in a benchtop shaker set at 1000 rpm for 15 min. Following dissociation  TrypLE was inactivated with goat serum. To remove undissociated chunks and debris  the solution was passed through a 40 \u03bcm cell strainer Miltenyi Biotec  130 041 407. Cells were pelleted by centrifugation at 500 g for 5 min at 4\u00b0C with soft stop setting. The supernatant was carefully discarded and the pellet re suspended in 500 \u03bcl of PBS. To remove dead cells  Calcein violet Thermo Fisher  C34858 or Draq7 Thermo Fisher  D15105 was added at a final concentration of 1 \u00b5M and 3 \u00b5M  respectively  and the cell suspension was incubated at room temperature for 20 min. The single cell preparation was sorted using appropriate gates  including excitation with UV 405 nm or a 633 nm laser for identifying live cells with Calcein+ or Draq7   respectively. FACS was performed  using a 100 \u00b5m nozzle  and a minimum of 15 000 live cells per condition were collected into BSA coated tubes containing 1% BSA in PBS. Sorting time did not exceed 15 min. For single cell RNA sequencing using the 10x Genomics platform  the cell suspension was adjusted with PBS to a density of 300 cells/\u00b5l and diluted with nuclease free water according to the manufacturer's instructions to yield 7 000 cells.

This current paradigm of regenerative flexibility in the liver has been established for animals with little or no growth. However  the regenerative mechanisms during periods of growth in young animals remain unexplored. Here  we establish two new partial liver injury protocols in the zebrafish model of rapid growth during late larval stage and observe emergence of de novo hepatocytes in the presence of spared hepatocytes. Using single cell RNA sequencing and lineage tracing  we identify cholangiocytes as the source of de novo hepatocytes. Our study offers a new perspective on the current paradigm of liver regenerating by proposing cholangiocyte to hepatocyte transdifferentiation as the default mechanism of hepatocyte recovery in late larval stage zebrafish. Overall design: We conducted single cell RNA Sequencing using the 10x platform of larval zebrafish liver.

To remove dead cells  Calcein violet Thermo Fisher  C34858 or Draq7 Thermo Fisher  D15105 was added at a final concentration of 1 \u00b5M and 3 \u00b5M  respectively  and the cell suspension was incubated at room temperature for 20 min.
