It will also open the road to new therapies in order to fight diseases resulting from improper signaling. Through the extracellular domain, integrins associate with the extracellular matrix (ECM) providing anchorage.19 Integrins are also responsible for the formation of platelet aggregates, and intracellular junctions in the immune system.20 Specifically related to carcinoma, integrins are responsible for bacterial and viral entry of infectious diseases.20 In addition, they play a critical role in signaling.17. Because they showed critical functions in the control of fundamental biological processes, including cell proliferation and differentiation, homeostasis, development, and other important biological processes, they have provided the key for the understanding of several pathological situations, among which cancers were of prime concern.

The fracture gap size influences the local vascularization and tissue differentiation in callus healing. developed a novel hydroxyapatite-coated double-network hydrogel. Recently, two of the CCN proteins were also reported to modulate channel ion signaling [16]. Finally, unique bioactives, specifically growth factors, are used to prompt cellular activity in order to regenerate skeletal tissue.54 Bone Morphogenetic Proteins (BMPs) play an important role in signal transduction and promote the proliferation and differentiation of osteoblast cells.55 For this reason, BMP-2 is frequently used in the treatment of bone defects.48 While drug delivery systems for growth factors exist, they maintain poor in vivo stability.56 Growth factor treatment is typically used in conjunction with bioengineered scaffolds which will house cells that either naturally release growth factors, or are specifically engineered to release growth factors which promote angiogenesis.3 Unfortunately, the introduction of growth factors to a known cancerous area, such as the resection site in a patient with osteosarcoma, is not advised. As mentioned previously, BMPs are one of the most crucial growth factors for both bone formation and healing. Article 3D printing allows for the construction of complex structures with a variety of different materials and growth factors while maintaining a high level of control over pore size and interconnectivity.

Enhanced hydrogels often contain bioactive molecules that further work to enhance bone tissue regeneration. Many receptors have been identified and shown to play critical roles in the adaptative cell response. Results from Quilan et al.70 show that rhBMP-2 was successfully released. Loss of skeletal tissue is the result of aging, injury, and disease thereby bolstering the need for skeletal regeneration to become a prominent focus of the tissue engineering field.4 Examples of diseases requiring bone tissue repair include osteoporosis, renal osteodystrophy (increase in parathyroid hormone and delay in bone mineralization), Pagets Disease of Bone (bone crippling disorder), osteogenesis imperfecta (OI) (stillborn infants due to fractures in utero and inability to breathe), and osteosarcoma (malignant tumor of bone).5 In this article, we provide an in-depth review of the natural bone healing process from integrins to growth factors and the repair cascade, and assess high-level biomedical applications used to treat skeletal tissue loss as the result of osteosarcoma and other disease states, as well as recent breakthroughs in the field of skeletal tissue regeneration that provide a path forward. In each case, individual cell reactions are transmitted via inter cellular signals to neighbouring cells and integrated to generate a global cellular response at the level of tissues, organ and body.

Huddleston PM, Steckelberg JM, Hanssen AD, et al. 3D printing utilizes a liquid binder printed onto powdered biomaterials in order to create a three dimensional structure which functions as a scaffold.60 These 3D printing techniques are becoming the most ideal for creating scaffolds which have optimal pore size and spatial distribution as well as being biodegradable.61 Many different materials including ceramic, metallic, and polymeric blends can be used in the 3D printing process, though the best are those which mimic the natural strength and porosity of bone.62 Today, Calcium Phosphate-based ceramics are commonly used as a means to regenerate skeletal tissue due to their excellent bioactivity, osteoconductivity, and similarities in composition to natural bone.62 In addition to biocompatibility, 3D printing is also valuable in that the scaffolds are customizable thanks to quick data processing and advances in printers.63 Unlike traditional bone grafts, 3D bone replacements can be molded based on imaging sometime before surgery, leading to less manual manipulation by the surgeon while the patient is still under anesthesia. Not surprisingly, integrins are closely tied to angiogenesis. Another famous family of signaling components is represented by the G-protein-coupled receptors, often referred to as seven transmembrane (7TM) domains receptors.

Open access has four broad benefits for science and the general public. Surgical resection of diseased bone in patients with osteosarcoma, as previously described, is challenging in that the size of resection can be quite large depending on the grade of severity. The insulin like growth factors play a large role in regulating cell growth, apoptosis, and differentiation in many cell types.33 Specifically, the activity of IGF-I and IGF-II is mediated by the IGF type 1 receptor.33 A pertinent component of the IGF pathway, is the insulin growth factor binding protein 3 (IGFBP-3) which plays a key role in tumor formation.39 This is directly relatable to Osteosarcoma as IGFs are produced by osteoblasts and are the most abundant growth factor stored in the bone.40 More specifically the IGFBP-3 gene is activated by the tumor suppressor gene, p53, which encodes for the protein responsible for the cell cycle G1 arrest.33,41 This is due to the ability of p53 to induce the expression of p21WAF1/CIP1/Sdi1, which is an inhibitor of cyclin dependent kinases 2, 3, 4, and 6.41 These cyclin dependent kinases are enzymes responsible for several checkpoints within the cell cycle.
