(13) These observations suggest that the function of BMG is to evoke mesenchymal cell differentiation into prechondroblasts during the latent or migratory morphogenetic phase while the effect of the culture medium is to provide the bionutritional requirements for synthesis of hyaline cartilage matrix by chondrocytes during the patent phase of development.

Fibrocartilage
Definition:
(n.) A kind of cartilage with a fibrous matrix and approaching fibrous connective tissue in structure.
Example Sentences:
(1) In the capsule of the fibrocartilage cells, parallel orientated filaments exhibit a periodical arrangement.
(2) Findings at surgery included chondromalacia of the ulnar head (19), tears of the triangular fibrocartilage complex (11), and excessive mobility of the ulnar head (10).
(3) By 16 weeks, fibrocartilage had filled the void in the curetted disc spaces.
(4) In the control males given the vehicle alone, the proximal segment of the os penis, composed of a compact cell mass found at day 0, developed at 5 days into the membrane bone with bone marrow and hyaline cartilage; the distal segment, composed of mesenchymatous cells until 10 days, developed at 30 days into fibrocartilage characterized by a distribution of type I collagen.
(5) Thus, fibrocartilage is least conspicuous where there is little motility near an attachment site.
(6) Interactions among the important constituents of the fibrocartilage matrix cause meniscal tissue to behave as a fiber-reinforced, porous, permeable composite material similar to articular cartilage, in which frictional drag caused by fluid flow governs its response to dynamic loading.
(7) Transverse loading tests demonstrated that the triangular fibrocartilage is less stiff in neutral forearm rotation.
(8) Finally, the cells are once transformed in cartilage cells with a small reticulum or cells of fibrocartilage with a capsule and a decreased cytoplasm; some cells are disintegrated.
