IPA: /ˈʧæl.oʊn/
KK: /ˈʧælən/
A type of substance produced by body tissues that can stop cell division in those tissues.
Chalones play a role in regulating cell growth and division in various tissues.
Chalone is derived from the Greek word "chalē" (χαλὴ), meaning to loosen or to release. The term is used in a biological context to refer to a substance that inhibits the growth of other cells, effectively 'loosening' or 'releasing' the control over cell proliferation.
Think of 'loosening' or 'releasing' when you hear 'chalone' — it refers to a substance that inhibits or controls growth.
