How the Hyaline Cartilage is Formed in the Siphonopoda as the Model of Higher Organisms?

Abstract

For several decades attempts have been made to find evidence for the origination of tissue and the mechanism of the formation of hyaline cartilage; however, no definition for the mechanism was provided to support that. Thus, the current study presented and explained the mechanism and origins of the formation process of cartilage by using three different stains and determining the corpuscle cell, which is responsible for the formation and division process as the primary unify of the cartilage formation in animals, particularly in vertebrates. The hyaline cartilage is originated from connective tissue (collagen fiber). The current work explained the condensation of collagen fibber in tissue passing to the two divided origin cells, then the nucleus begins formation at each side of cartilage in all new cells, followed by a step during which the cartilage divides the cell passing from the cartilage cell into two cells. Determination of the origin of cartilage and its mechanism is great evidence that may explain bone and cartilage diseases and facilitate their treatment. These common unknown diseases are attributed to the deficiency of information about cartilage formation and the ignorance of all previous steps.
