92) Megarian Banded Centipede, Scolopendra cingulata
Mediterranean Banded Centipedes can be found near the Mediterranean sea (McMillion & Yach). This centipede is able to regenerate its midgut after it has been damaged in some way.
The migut of this centipede has regenerative cells that are able to begin the mitosis phase in the day and divide at night (Chajec et al.). The regenerative cells are found in the basal lamina of the midgut and are treated as multipotent stem cells (Chajec et al.). After the midgut is injured the regenerative cells begin to proliferate and acculumate in the epithelium. In the cytoplasm of the regenerative cells are many mitochondria, autophagosomes, and multivesicular bodies (Chajec et al.). Mitochondria’s are used to help proliferate and differentiate the cells in the epithelium. Autophagosomes promote cell survival which helps the epithelium structurally sound. Multivesicular bodies also help in protecting the epithelium from harm. The regenerative cells divide into a midgut stem cell, which differentiates into secretory cells, and a midgut progenitor cell, which differentiates into digestive cells (Chajec et al.). The regenerative cells continue to divide and to regenerate the midgut epithelium until it has been fully reformed. Once the midgut has regenerated the cells will stop dividing and go into the quiescent stage of mitosis.
