So regeneration can happen via: Division of the tissue cells (skin healing, liver regeneration) Differentiation of stem cells (erythropoesis, muscle regeneration) Organs that do not have non-dividing cells can regenerate by simply proliferating whereas others would need to maintain a stem cell niche- which is not possible in all tissues.
