Cell cycle control in growth plate chondrocytes.
Growth of endochondral bones is regulated by the coordinated proliferation and differentiation of chondrocytes in the epiphyseal growth plates. Many skeletal diseases are caused by pathogenic disruptions of these two processes. While the intracellular mechanisms regulating chondrocyte proliferation and differentiation are poorly understood, recent evidence from studies using genetically altered...
متن کاملMatrix metalloproteinases: role in skeletal development and growth plate disorders.
Differentiation is the cellular process that regulates development of long bones and joint surface cartilage of synovial cavities. Growth plate cartilage development is commonly referred to as endochondral ossification which is the end stage of long bone development. Endochondral ossification proceeds as a continuum of chondrocyte proliferation cycles followed by non-proliferative phases couple...
متن کاملApoptosis and proliferation of growth plate chondrocytes in rabbits.
The growth plates of the femoral head of Japanese white rabbits aged 5, 10, 15 and 20 weeks were stained for apoptotic and proliferating chondrocytes using the TUNEL and PCNA antibody staining techniques. Both TUNEL- and PCNA-positive chondrocytes were detected in all of the specimens. The positive ratios of both stainings were calculated for the whole plate and for the resting, proliferating a...
متن کاملNicotine Acts on Growth Plate Chondrocytes to Delay Skeletal Growth through the α7 Neuronal Nicotinic Acetylcholine Receptor
BACKGROUND Cigarette smoking adversely affects endochondral ossification during the course of skeletal growth. Among a plethora of cigarette chemicals, nicotine is one of the primary candidate compounds responsible for the cause of smoking-induced delayed skeletal growth. However, the possible mechanism of delayed skeletal growth caused by nicotine remains unclarified. In the last decade, local...
متن کاملNoncanonical frizzled signaling regulates cell polarity of growth plate chondrocytes.
Bone growth is driven by cell proliferation and the subsequent hypertrophy of chondrocytes arranged in columns of discoid cells that resemble stacks of coins. However, the molecular mechanisms that direct column formation and the importance of columnar organization to bone morphogenesis are not known. Here, we show in chick that discoid proliferative chondrocytes orient the division plane to ge...
