“…Runx is necessary for the correct structure of osteoblast cells. It promotes bone mineralisation, osteoblast proliferation and induces mesenchymal cell differentiation into immature osteoblasts until the final stage of the process in which maturity of osteoblasts is inhibited (Dos Santos Pereira et al, 2017). Our results indicated that there was no statistically significant difference between the CLP group and the control group, but the numbers of Runx2 positive structures in the bone and cartilage tissue was low, indicating reduced mineralisation potential of the hard tissue.…”

“…The BMPs and the FGFs regulate transcription of Runx2. Runx2 also induces mesenchymal cell differentiation into immature osteoblasts until the final stage of the process during which maturity of the osteoblasts are inhibited (Komori, 2010;Dos Santos Pereira et al, 2017). A study on Chinese patients showed that normal distribution of the Runx2 also might be a reason for cranial dysplasia due to the mutation in the Runt domain, which leads the impaired transaction activities of Runx2 (Zhang et al, 2017).…”

Bone repair after surgical intervention on cleft lip palate (CLP) depends on the coordinated action of multiple tissue regeneration factors. We determined the relative number and appearance of tissue factors: matrix metalloproteinase-2 (MMP-2), tissue inhibitor of metalloproteinase-2 (TIMP-2), bone morphogenetic protein 2/4 (BMP 2/4), transforming growth factor beta (TGF-ß), Wnt3a protein (Wnt3a), Runt-related transcription factor 2 (Runx2), basic fibroblast growth factor (bFGF) and osteoprotegerin in hard tissue of CLP patients during first time surgical intervention. Fourty-three CLP patients with 24 bone and 36 cartilage samples were involved. Immunohistochemistry was used to assess the levels of tissue factors and the semi-quantitative census method was used for quantification of immunological structures. The increased amount of MMP-2 and bFGF positive cells was detected in the CLP group in cartilage and bone (p < 0.05), compared to the controls. A statistically significant (p = 0.012) increased amount of BMP 2/4 positive cells was found in cartilage of CLP patients, in comparison to the control group. Increased appearance of MMP-2, bFGF in hard tissue of the CLP patients indicates the predominance of tissue degradation. Increased number of BMP2/4 positive chondrocytes suggests improved cartilage growth and better regeneration in CLP patients.

“…For the reaction revelation, we used Diaminobenzidine (Dako Laboratories, Santa Clara, CA, USA) and performed counterstaining with Harris hematoxylin. After dehydration through xylene, the researchers mounted coverslips over the sections to evaluate and utilize a scoring system in accordance with dos Santos Pereira et al [ 26 ], which was performed by a single evaluator who had been previously calibrated. Scores were in the range of 0 (absence of staining), 1 (low staining), 2 (moderate staining), and 3 (intense staining).…”

The study aimed to assess the efficacy of using Raloxifene with ultrasonic processing to enhance Bio-Oss®, a bone graft substitute, for maxillary sinus bone height reconstruction. A total of 24 rabbit maxillary sinuses were distributed into three groups, each receiving different treatments: Bio-Oss® only, sonicated Bio-Oss, and sonicated Bio-Oss® with Raloxifene. Surgical procedures and subsequent histomorphometric and immunohistochemistry analyses were conducted to evaluate the bone formation, connective tissue, and remaining biomaterial, as well as the osteoblastic differentiation and maturation of collagen fibers. Results indicated that the sonicated Bio-Oss® and Bio-Oss® groups showed similar histological behavior and bone formation, but the Raloxifene group displayed inflammatory infiltrate, low bone formation, and disorganized connective tissue. The statistical analysis confirmed significant differences between the groups in terms of bone formation, connective tissue, and remaining biomaterial. In conclusion, the study found that while sonicated Bio-Oss® performed comparably to Bio-Oss® alone, the addition of Raloxifene led to an unexpected delay in bone repair. The findings stress the importance of histological evaluation for accurate bone repair assessment and the necessity for further investigation into the local application of Raloxifene. Future research may focus on optimizing bone substitutes with growth factors to improve bone repair.

“…There are a number of successful Ca-P ceramic scaffolds or fillers already available on the market used in cancellous bone replacement in non load-bearing indications (JectOS/ARE-X®BONE, CustomBone®, CronOS®, Engipore®). Unfortunately clinical solutions for cortical bone regeneration remain extremely limited [9,[18][19][20][21][22].…”

Biomaterial science increasingly seeks more biomimetic scaffolds that functionally augment the native bone tissue. In this paper, a new concept of a structural scaffold design is presented where the physiological multi-scale architecture is fully incorporated in a single-scaffold solution. Hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP) bioceramic scaffolds with different bioinspired porosity, mimicking the spongy and cortical bone tissue, were studied. In vitro experiments, looking at the mesenchymal stem cells behaviour, were conducted in a perfusion bioreactor that mimics the physiological conditions in terms of interstitial fluid flow and associated induced shear stress. All the biomaterials enhanced cell adhesion and cell viability. Cortical bone scaffolds, with an aligned architecture, induced an overexpression of several late stage genes involved in the process of osteogenic differentiation compared to the spongy bone scaffolds. This study reveals the exciting prospect of bioinspired porous designed ceramic scaffolds that combines both cortical and cancellous bone in a single ceramic bone graft. It is prospected that dual core shell scaffold could significantly modulate osteogenic processes, once implanted in patients, rapidly forming mature bone tissue at the tissue interface, followed by subsequent bone maturation in the inner spongy structure.
