Abstract:
Regeneration is the ability of cells to restore lost or damaged tissues and organs in adults by pathways that mimic developmental processes. Although many of the molecular mechanisms that control cellular differentiation and growth during embryogenesis recur during fracture healing, these processes take place in a postnatal environment that is unique and distinct from those that exist during embryogenesis. Bone tissue has a remarkable capacity of regeneration without scarring. This article highlights central biological and molecular processes that are crucial in embryonic bone development. Several animal bone regeneration models are described. The patterns of gene expression during the regeneration process in the different models are reviewed. Exploring the similarities and the differences in the molecular processes in different models will contribute to the understanding of their potential in the processes of bone regeneration and tissue engineering.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
