Wounded soft tissues undergo repair through a complex series of interrelated events that involve both physical and chemical activities. These processes are currently undergoing extensive investigation as efforts are directed toward achieving augmented and accelerated healing. Early wound-healing research focused on expanding traditional histologic(More)
When bone is fractured, a sequence of dynamic events ensue to restore form and therefore function. Many key biologic cell regulators for these events have been identified, expressed through recombinant technology, and their roles posited. Moreover, the availability of recombinantly engineered molecules, such as the bone morphogenetic proteins with their(More)
Osteoblast biology is influenced in vivo by a 3-dimensional (3D) extracellular matrix that mediates their adhesion and interaction and by a constant state of compressive and tensile forces. To study the role of mechanical stress on osteoblasts in vitro, these parameters must be addressed. Therefore, this study describes the use of a novel, in vitro system(More)
BACKGROUND Distraction osteogenesis has been used to correct hypoplastic and asymmetric bony deformities in the growing patient, yet its underlying cellular mechanisms are poorly understood. Using a new in vitro model, the microdistractor, morphologic properties of preosteoblasts under mechanical strain were studied. METHODS Mouse calvarial MC3T3 cells(More)
