Abstract:
Abstract: Planarian has powerful regenerative ability and the research on its mechanisms for regeneration has always been the hot spot of developmental biology. Wnt signaling is one of the most crucial pathways during the development of animals and plays a vital role in the growth and development of the organisms. Progresses have been continuously made in cloning and phylogenetic analysis， expression pattern during regeneration and functional analysis of the planarian wnt genes in recent years. In this paper， research advances in planarian wnt genes were reviewed.
Key words: planarian; regeneration; wnt; expression; function
