Regeneration in White Sea sponge Leucosolenia complicata (Porifera, Calcarea).
International audience Sponges (phylum Porifera) possess the remarkable regenerative abilities and great diversity of the regeneration mechanisms. The current study dealt with the regener-ation of calcareous sponge Leucosolenia complicata. Two types of experiments on L. complicata regeneration were...

International audience Sponges (phylum Porifera) possess the remarkable regenerative abilities and great diversity of the regeneration mechanisms. The current study dealt with the regener-ation of calcareous sponge Leucosolenia complicata.

We have combined in vivo light microscopy and histological studies to reveal morphogenetic mechanisms and determine the cell types involved in the reparative regeneration in this sponge.
