[Quantitative analysis of a differentiation characteristic of hyaline cartilage in the aging process].

Abstract

Changes in the distribution patterns of chondrocytes in the permanent hyaline cartilage were studied in order to analyze a process of differentiation quantitatively. Sections of 29 specimens of arytenoid cartilage and 42 specimens of Carina tracheae from newborn up to the age of 91 years were used. The chondrocytes were transferred via a mirror to paper, and the resulting patterns were analyzed. Various distribution functions were calculated. The most important one is the pair correlation function. The behavior of the differentiation is resembling in both organs. Especially in arytenoid cartilage there were found the following results: The clearest process of differentiation took place up to the 3rd decade of life. Initial hard core distribution is followed by soft core distribution up to the final of puberty. After the 2nd decade of life clustering was found. The grade of differentiation decreases in the 5th decade of life and later.
