Enlargement of growth plate chondrocytes modulated by sustained mechanical loading.
BACKGROUND Mechanical compression and distraction forces are known to modulate growth in vertebral growth plates, and they have been implicated in the progression of scoliosis. This study was performed to test the hypothesis that growth differences produced by sustained compression or distraction loading of vertebrae are associated with alterations in the amount of increase in the height of gro...
متن کاملCell 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 کاملRegulation of PTHrP expression by cyclic mechanical strain in postnatal growth plate chondrocytes.
Mechanical loading has been widely considered to be a crucial regulatory factor for growth plate development, but the exact mechanisms of this regulation are still not completely understood. In the growth plate, parathyroid hormone-related protein (PTHrP) regulates chondrocyte differentiation and longitudinal growth. Cyclic mechanical strain has been demonstrated to influence growth plate chond...
متن کاملDifferential Diagnosis of Secondary Center of Ossification Abnormalities
The anatomy of a child’s bone may be divided into its basic components: the epiphysis, physis, metaphysis, and diaphysis. An appreciation of the growth and function of each structure is critical whenever a clinician encounters pathologies in the pediatric skeleton. The following review discusses the differential diagnoses of abnormal secondary centers of ossification (SCO), a topic which is inf...
متن کاملOsteogenic capillaries orchestrate growth plate-independent ossification of the malleus
Endochondral ossification is a developmental process by which cartilage is replaced by bone. Terminally differentiated hypertrophic chondrocytes are calcified, vascularized, and removed by chondroclasts before bone matrix is laid down by osteoblasts. In mammals, the malleus is one of three auditory ossicles that transmit vibrations of the tympanic membrane to the inner ear. The malleus is forme...
