Article Abstract

This review focuses on recently developed alginate injectable hydrogels and alginate composites for applications in bone tissue regeneration, and it evaluates the alternatives to overcome the problems that avoid their utilization in the field. Section 2 covers the properties of alginates that have made them useful for medical applications, in particular their ionic gelling ability for preparing injectable compositions used as delivery drugs systems. The advantages and shortcomings of these preparations are revised together with the chemical modifications assayed. Section 3 describes how it has been taken advantage of alginates into the new field of biofabrication and the developments in bone engineering. The state of the art of this field is reviewed. Finally in Section 4, new developments and approaches that in opinion of the authors can lead to a breakthrough in bone tissue engineering using alginates are introduced.

Polymer/ceramic nanocomposites integrated the advantages of both polymers and ceramics for a wide range of biomedical applications, such as bone tissue repair. Here, we reported triphasic poly(lactic--glycolic acid) (PLGA, LA/GA = 90:10) nanocomposites with improved dispersion of hydroxyapatite (HA) and magnesium oxide (MgO) nanoparticles using a process that integrated the benefits of ultrasonic energy and dual asymmetric centrifugal mixing. We characterized the microstructure and composition of the nanocomposites and evaluated the effects of the HA/MgO ratios on degradation behavior and cell-material interactions.

This study aims to compare the expression levels of tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) in osteoblasts infiltrated with H37Rv (H37Rv) and to understand the differential bone destruction in spinal tuberculosis (STB) versus spondylitis (BS). Primary osteoblasts were isolated and cultured from the cranial bones of 2-5 days old mice and characterized by alkaline phosphatase (ALP) staining and alizarin red staining (ARS). H37Rv and were cultured to the logarithmic phase, and transfection solutions were prepared.

Osteoporosis, affecting the entire skeletal system, can cause bone mass to diminish, thereby reducing bone strength and elevating fracture risk. Fracture nonunion and bone defects are common in patients with fractures, and pain and loss of function may cause serious distress. The search for a new therapeutic strategy is essential because of the limited therapeutic options available.

The increasing number of elderly people across the globe has led to a rise in osteoporosis and bone fractures, significantly impacting the quality of life and posing substantial health and economic burdens. Despite the development of tissue-engineered bone constructs and stem cell-based therapies to address these challenges, their efficacy is compromised by inadequate vascularization and innervation during bone repair. Innervation plays a pivotal role in tissue regeneration, including bone repair, and various techniques have been developed to fabricate innervated bone scaffolds for clinical use.

Synthetic bone transplantation has emerged in recent years as a highly promising strategy to address the major clinical challenge of bone tissue defects. In this field, bioactive glasses (BGs) have been widely recognized as a viable alternative to traditional bone substitutes due to their unique advantages, including favorable biocompatibility, pronounced bioactivity, excellent biodegradability, and superior osseointegration properties. This article begins with a comprehensive overview of the development and success of BGs in bone tissue engineering, and then focuses on their composite reinforcement systems with biodegradable metals, calcium-phosphorus (Ca-P)-based bioceramics, and biodegradable medical polymers, respectively.
