Enhancing the wound healing potential using earthworm clitellum factors and elucidating its molecular mechanism in an in-vitro and earthworm model.

Earthworm, Eudrilus eugeniae cannot survive and regenerate without clitellum segments. In regenerating worms, the clitellum's epithelial and circular muscular layers are reduced to one-third, and longitudinal cell layers to half. In C2C12 cells, Clitellum Factors (CF - 5, 25 and 50%) and Regenerative Clitellum Factors (RCF - 5, 25, 50, 75%) ameliorate the cell viability up to 20-28% and 30-38% respectively than the control.

Functional significance of earthworm clitellum in regulating the various biological aspects of cell survival and regeneration.

Earthworms are a highly abundant species in nature, with nearly 7000 different species being discovered. Despite the similarities in morphology among earthworm species, their regeneration capabilities vary based on the clitellum. The clitellum plays a crucial role in the clitellum-dependent worms, as it is involved in the processes of regeneration and reproduction in earthworms.
