The Sikes Lab is broadly interested in understanding the postembryonic developmental processes of regeneration and asexual reproduction. Our research focuses on two groups of flatworms (planarians and acoels) that possess robust abilities to regenerate lost structures and to reproduce via fission and budding. We use a variety of molecular, phylogenetic, and developmental tools to better understand how these divergent invertebrates accomplish asexual reproduction and regeneration.  







Convolutriloba macropyga
Schmidtea mediterranea

Acoels are marine flatworms representing one of the two clades with the recently erected phylum Acoelomorpha. With a phylogenetic position basal to all other bilaterians, acoels serve as a model for understanding the evolution and development of animal bodyplans. We utilize acoels of the genus Convolutriloba to investigate how radically different modes of asexual reproduction evolve.

Planarians are freshwater Turbellarian Platyhelminths that have emerged as a model for the study of invertebrate regeneration. These animals possess extraordinary abilites to replace lost body parts. While most studies utilize the model planarian Schmidtea mediterranea, comparative studies using different planarian species are often used to understand regeneration from an evolutionary perspective.
