Determination and differentiation is easy to observe during embryogenesis and larval imaginal disc development but not during metamorphosis, because the pupae are opaque, the larval tissue is undergoing histolysis
and the developing imaginal tissue is fragile.
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).

In other polymorphic insects, flightless morphs result from wing muscle histolysis
even though fully developed wings remain (Borden and Slater 1969, Dingle 1985).

firmus, addressing two main questions: (1) are the traits involved in the trade-off (call duration, wing morph and flight muscle condition - a measure of the degree of histolysis
) significantly heritable?
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).
Simitar events, which involve the shedding or histolysis
of the larval epidermis variously called "serosa" or "test," occur during development of some other spiralians, for example the stenocalymma larva of the scapho-pod mollusc Dentalium (Lacaze-Duthiers, 1856; after Buckland-Nicks et al., 2002), the test larva of neomen-ioid aplacophorans (Thompson, 1960: Okusu, 2002), and the pericalymma of the protobranch bivalve molluscs (Gustafson and Reid, 1986; Gustafson and Lutz, 1992; Zardus and Morse, 1998), as well as the unusual larva of the sipunculid Sipuncultts nuchts (Gerould.
