Chemical and Biochemical Basis of Cell-Bone Matrix Interaction in Health and Disease

Abstract: Bone, a calcified tissue composed of 60% inorganic component (hydroxyapatite), 10% water and 30% organic component (proteins), has three functions: providing mechanical support for locomotion, protecting vital organs, and regulating mineral homeostasis. A lifelong execution of these functions depends on a healthy skeleton, which is maintained by constant bone remodeling in which old bone is removed by the bone-resorbing cell, osteoclasts, and then replaced by new bone formed by the bone-forming cell, osteoblas… Show more

“…By alteration of their surface characteristics, scaffolds can be tailored towards specific needs: It was demonstrated that different coatings of scaffold surfaces have individual impacts on their osteogenic properties—Gelatin coating improved the osteogenic properties of BG‐based scaffolds compared with coatings with other biocompatible polymers (Westhauser, Weis, et al, ). Gelatin is a naturally occurring biopolymer composed of hydrolysed Type 1 collagen, which also represents the main portion of the organic osseous ECM (Echave, Burgo, Pedraz, & Gorka, ; Feng, ). During the process of cell migration on scaffold surfaces, cells form clots in order to adhere (Salgado António et al, ).…”

“…O osso é um tecido conjuntivo que continuamente sofre remodelação através do acoplamento preciso e localizado da reabsorção (remoção do material envelhecido), promovida pelas células denominadas osteoclastos, com a substituição pelo novo tecido ósseo formado, decorrente da ação de células intituladas osteoblastos. 11,12 Materialmente, é constituído, em peso, 90% pela matriz extracelular e 10% água. 12,13 Essa matriz, conhecida como matriz óssea, é um material híbrido orgânico-inorgânico tridimensional, que consiste em cerca de 60% de componente inorgânico e 30 % de fase orgânica.…”
