Transgenesis in the acoel worm Hofstenia miamia.

ABSTRACT: The acoel worm Hofstenia miamia, which can replace tissue lost to injury via differentiation of a population of stem cells, has emerged as a new research organism for studying regeneration. To enhance the depth of mechanistic studies in this system, we devised a protocol for microinjection into embryonic cells that resulted in stable transgene integration into the genome and generated animals with tissue-specific fluorescent transgene expression in epidermis, gut, and muscle. We demonstrate that transgenic Hofstenia are amenable to the isolation of specific cell types, investigations of regeneration, tracking of photoconverted molecules, and live imaging. Further, our stable transgenic lines revealed insights into the biology of Hofstenia, including a high-resolution three-dimensional view
