I read in National Council for Education and Training study guide (NCERT) that Planaria (flat worms) undergo true regeneration. The key difference between regeneration and fibrosis is that regeneration involves replacing injured cells with cells of the same type while fibrosis involves replacing parenchyma tissue with connective tissues, leading to the formation of permanent scar tissue..
