title: The human blood platelet: its derivation from the red blood cell. II. Instantaneous changes in form in the platelet and red cell. A morphologic study.
abstract: The human blood platelet arises from the interior of the red cell instantaneously as blood is either damaged or disturbed. The platelet starts out as a fine granular structure that rather suddenly changes in form and function with the passage of a very small amount of time.
