Hofstenia, or panther worms,^[1] is a genus of acoels belonging to the family Hofsteniidae.^[2]

They are recognized for their ability to regenerate any missing tissue type and recover body axes following injury^[3] including a functional brain during whole-body regeneration.^[4] The Hofstenia body is populated by neoblast-like cells,^[3] adult stem cells, which are necessary for Hofstenia regeneration, and are frequently studied in planarians.
