What's the difference between cartilage and chondrogenesis?
Cartilage
Definition:
(n.) A translucent, elastic tissue; gristle.
Example Sentences:

(12) The buccal glands of adults of the Southern Hemisphere lamprey Geotria australis consist of a pair of small, bean-shaped, hollow sacs, embedded within the basilaris muscle in the region below the eyes and to either side of the piston cartilage.
(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.
(14) The cartilage of the concha is a valuable substitute of the bridge and the posterior wall of the external auditory conduct.
(15) the synovium has a) a direct, presumably enzymatic action on cartilage matrix and b) an indirect effect mediated through the chondrocytes.
(16) New insights into the biochemical and cell-biological alterations occurring in articular cartilage during the early phase of osteoarthrosis (OA) have been gained in the past decade by analysing experimentally induced osteoarthrosis in animals, mostly dogs and rabbits, while early phases of OA in humans so far have escaped diagnostic evaluation.
(17) The use of SDS-polyacrylamide gel electrophoresis of the cyanogen bromide derived peptides from fibrous cartilage collagens enabled to calculate type I to type II collagen ratio in this tissue.
(18) After transplantation chondrocytes from regenerated cartilage reconstructed cartilage in one out of ten transplants.
(19) Chemically isolated separate preparations of the non-aggregating protein-chondroitin-keratin sulphate (PCKS) fraction from the hyaline cartilage and hyaluronic acid (HUA) of the vitreous body and of the umbilicus were investigated by electron microscopy.
(20) Standard methods of glycosaminoglycan separation were used to confirm the presence of hyaluronic acid in sheep and rabbit articular cartilage.
Chondrogenesis
Definition:
(n.) The development of cartilage.
Example Sentences:
(1) The results reveal strong similarities between mesenchymal chondrosarcoma and normal chondrogenesis.
(2) We report now that the hormonal metabolite of vitamin D3, namely 1,25-dihydroxyvitamin D3, stimulates chondrogenesis in cultures of stage 24 chick embryo limb bud mesenchymal cells, as evidenced by morphologic changes as well as by increased transcription of collagen type II and core protein genes.
(3) Our results show that BBE stimulates chondrogenesis in a dose-dependent manner and by a specific, direct action on the chondroprogenitor cells but not in normally non-chondrogenic, low density or 'young' limb bud cell cultures.
(4) The DM contains minimal additives (insulin, hydrocortisone, and in some cases, ascorbate or transferrin) and supports both chondrogenesis and myogenesis.
(5) Chondrogenesis and osteogenesis of the os penis were caused by androgens, while the rudiments of the os penis were formed independently of androgens.
(6) The exclusively inhibitory effect of retinoic acid (RA) on chondrogenesis in standard serum-containing cultures of limb-bud mesenchymal cells is equally well known and has provided a means to explore the cellular basis for RA-mediated skeletal teratogenesis.
(7) Concanavalin A and, to a lesser degree, other immunomodulators applied, when administered subcutaneously into the pinna, also have induced perichondrial chondrogenesis.
(8) Cooper (1965) found the cartilage cells from epihysis of the long bones of chick failed to induce chondrogenesis in somites in mice and chick whereas flat cells and early Peripheral cells could do same.
(9) The cartilage-type proteoglycan (H) was first detectable on day 14 of gestation, indicating that chondrogenesis in rat forelimb plates starts on day 14 of gestation.
(10) In contrast, neither condensation nor subsequent chondrogenesis was stimulated by transient treatment with TGF-beta 1 on the day of plating.
(11) A new hypothesis is presented according to which regulation of the direction of condylar growth is achieved by choosing the cells for chondrogenesis more posteriorly or anteriorly from among the mesenchymal cells covering the whole condylar cartilage.
(12) Evaluation of chondrogenesis was performed after alcian blue staining, using a simple random hit counting of cartilage nodules.
(13) In vivo the interdigital mesenchyme of the duck leg bud subjected to ectoderm removal forms ectopic foci of chondrogenesis with a range of incidence similar to that in the chick.
(14) Synthesis of sulfated proteoglycans, an index of chondrogenesis, was inhibited by all three PDGF isoforms (PDGF-AA, PDGF-AB, and PDGF-BB).
(15) Gamma radiation inhibited both cell proliferation and chondrogenesis in a dose- and time-dependent fashion.
(16) Myogenesis and chondrogenesis occur independently in culture, consistent with the idea that these two differentiated cells are derived from two separate cell populations.
(17) Chondrogenesis was measured using a number of criteria, including (1) cartilage nodule production, (2) spectrophotometric determination of the amount of bound Alcian blue dye, and (3) computer-assisted analysis of the spatial distribution (area) and density of Alcian blue present in individual micromass colonies.
(18) Studies on the biosynthesis of proteoglycan as an index of limb chondrogenesis demonstrated that TBZ impaired its biosynthesis in the limb bud cell system.
