During the pupal development internal tissues undergo histolysis
, histogenesis and differentiation to form adult internal organs and sclerotized appendages.
Collectively, this habitat-adapted polymicrobial community residing in the root canal has several biological and pathogenic properties, such as antigenicity, mitogenic activity, chemotaxis, enzymatic histolysis
, and activation of host cells.
After the initial phase of wound closure and histolysis
of the most posterior region of the stump, the luminal epithelium and the mesothelium of the remaining anterior segments of the gut undergo typical dedifferentiation and give rise to the corresponding tissue layers of the missing parts of the alimentary canal, without any transdifferentiation events (Mashanov and Dolmatov, 2001).

8:15 Involvement of Lysosomal Activity in Flight Muscle Histolysis
In other polymorphic insects, flightless morphs result from wing muscle histolysis
even though fully developed wings remain (Borden and Slater 1969, Dingle 1985).
1983) extirpated the right forelimbs of Rana japonica tadpoles and histolysis
and perforation occurred normally.
Furthermore, for other wing-dimorphic insects, both the flight threshold and the extent of wing muscle histolysis
are negatively associated with the proportion of macropters in the population (Fairbairn 1986, Fairbairn and Desranleau 1987, Roff and Fairbairn 1991).
In holometabolous insects, midgut remodeling is important during metamorphosis, especially in mosquitoes; and EcR-B has been indicated to play an essential role in both histolysis
of larval tissue and differentiation of imaginal diploid cells (Parthasarathy & Palli 2007).
