Bone Mechanics Handbook, Second Edition by Stephen C. Cowin

By Stephen C. Cowin

This moment variation of the Bone Mechanics guide summarizes the present realizing of bone mechanics with entire insurance of the histology, body structure, and the phone and molecular biology of the bone. it truly is up to date with the newest advances on mechanical houses of the bone, such a lot particularly of cancellous bone, and the streaming potentials within the bone, which replicate the conclusion of the significance of fluid circulate in bone tissue

This causes an increase in areal bone ‘‘density’’ that plateaus. Remodeling rate is dominated by mechanical usage and modulated by parathyroid hormone, thyroxin, growth hormone, 1,25 (OH)2 vitamin D and microdamage. ’’ 70,71 These maps show BMU-based turnover or remodeling does differ in different parts of the skeleton and different parts of a given bone at any moment. The reason for many of those differences is not known. Possible reasons are as follows: (1) In the region where microdamage occurs BMU-based remodeling increases to try to repair it.

The cell–matrix and cell–cell interactions from signaling pathways assisted by integrin and cadherins play roles in osteoblast differentiation and mineralization of the osteoid matrix. 2 Origin and Fate The osteoblasts are derived from mesenchymal progenitors. Osteoblast precursors are located near bone surfaces: the periosteum, the endosteum, and the adjacent marrow stroma (perivascular parenchymal cells). They arise from local, undifferentiated intraskeletal mesenchymal cells that are capable of mitosis.

The rate of bone formation can be readily determined in humans and animals by administering tetracycline or other types of fluorescent bone markers. Tetracycline is an antibiotic that localizes at the mineralization front, thereby causing the newly deposited bone to appear as a tetracycline-labeled band. A labeled bone fluoresces under ultraviolet light and thus marks the location of bone formation at the time of tetracycline administration (Figs. 8 Major Growth Factors in Bone Formation and Fracture Repair Source of Factor Cellular Response Bone Morphogenetic Protein (BMP-2, -3, -4, and -7) Bone extracellular matrix Osteoblasts and osteoprogenitors Activation of cortical osteoblast Initiates differentiation of osteoprogenitor cells into osteoblasts Fibroblast Growth Factor (FGF-1 and -2) Inflammatory cells (macrophages) Mesenchymal cells Chondrocytes Osteoblasts Bone extracellular matrix Mitogenic effects on mesenchymal cells and osteoblasts Angiogenic actions Mesoderm induction TGF-␤ production Insulin Growth Factors (IGF-1 and -2, GFBP 3/5) Liver Osteoblasts Bone extracellular matrix Stimulating stem cell differentiation Increase bone turnover Mitogenic to osteoblast stimulates type I collagen production Platelet-Derived Growth Factor (PDGF-AA, -AB, -BB) Degranulating platelets Monocytes and macrophages Hypertrophic chondrocytes (PDGF-␣) Osteoblasts (PDGF-␤) Bone extracellular matrix Macrophage chemotaxis Mesenchymal cell chemotaxis Mesenchymal cell proliferation Angiogenic action Stimulates osteoblast proliferation Transforming Growth Factor-␤ (TGF-␤-1 and -2) Degranulating platelets Bone extracellular matrix Inflammatory cells Chondrocytes Osteoblasts Pleiotropic factor Osteoprogenitor cell proliferation Stimulates undifferentiated mesenchymal cell proliferation Stimulates extracellular matrix production Mitogenic effects on osteoblast stimulates alkaline phosphatase production stimulates collagen synthesis Note: Several other growth factors that stimulate osteoblasts in vitro: Epidermal growth factor (EGF) and vascular endothelial growth factor (VEGF) that could play a role in bone formation.
