Sewing up the wounds: the epithelial morphogenesis as a central mechanism of Leucosolenia complicata (Porifera, Calcarea) regeneration
Sponges are the earliest branching metazoans, and as such a key group for understanding of the evolutionary history of animal regeneration mechanisms. Sponges are known to possess remarkable reconstitutive and regenerative abilities. We investigated regeneration of Leucosolenia complicata, an abunda...

Sponges are the earliest branching metazoans, and as such a key group for understanding of the evolutionary history of animal regeneration mechanisms.
