Editing Neoteny (section)

== Subcellular neoteny ==

Neoteny is usually used to describe animal development; however, neoteny is also seen in the cell [[organelles]]. It was suggested that subcellular neoteny could explain why [[sperm cells]] have atypical [[centrioles]]. One of the two sperm centrioles of [[Drosophilidae|fruit fly]] exhibit the retention of "juvenile" centriole structure, which can be described as centriolar "neoteny". This neotenic, atypical centriole is known as the [[Proximal Centriole-Like]]. Typical centrioles form via a step by step process in which a cartwheel forms, then develops to become a procentriole, and further matures into a centriole. The neotenic centriole of fruit fly resembles an early procentriole.<ref>{{Citation |last1=Avidor-Reiss |first1=Tomer |last2=Turner |first2=Katerina |title=The Evolution of Centriole Structure: Heterochrony, Neoteny, and Hypermorphosis |date=2019 |url=https://doi.org/10.1007/978-3-030-23173-6_1 |work=The Golgi Apparatus and Centriole: Functions, Interactions and Role in Disease |pages=3–15 |editor-last=Kloc |editor-first=Malgorzata |access-date=12 October 2023 |series=Results and Problems in Cell Differentiation |place=Cham |publisher=Springer International |doi=10.1007/978-3-030-23173-6_1 |isbn=978-3-030-23173-6 |pmc=7576685 |pmid=31435789 |volume=67 }}</ref>
