Keynote: Xenohybrid scaffolds for bone regeneration
Biography:
Hard tissue regeneration is a complex phenomenon that involves intricate interplays within the patient autologous cells and the grafted material. Autologous bone remains the gold standard as it naturally presents appropriate mechanical and biological characteristics and avoids rejection or disease transmission risks. Nevertheless, a major limitation is represented by the available volume for removal from patient’s body alternative sides. A valid alternative, not limited in this sense, is represented by hybrid composite scaffolds. Taking advantage of porous and interconnected natural structures, such as the one of xenogeneic cancellous bone, it is possible to improve their characteristics via combination with other functional components. This way, mechanical and biological performance, similar to the one of autografts, can be obtained. In this contribution, we present a newly developed material (SmartBone®) which is composed of bovine bone, polymer and proteins. The mineral matrix provides adequate solid framework and open porosity, ensuring cells proliferation. The bioresorbable polymer reinforces the main structure and the collagen, exposing RGD sequences, stimulates blood cell’s adhesion. This way, this innovative scaffold is osteoconductive and osteoinductive, promoting complete remodeling to mature bone after 8-12 months, as supported by histological data. Since its launch on the market, this technology was successfully used on roughly 60,000 patients worldwide, covering dental and orthopedic applications. A relevant example of the many destination of use is visible in Figure 1, in which a customized solution for hip reconstruction after tumor removal is presented. During surgery, the piece was perfectly located inside the gap and firmly fixed with osteosynthesis titanium screws. Surgery was faster with respect to the standard procedures and very precise, allowing obtaining very satisfactory results both in terms of anatomical reconstruction and functionality. The post-operative follow-up recorded no issues and proceeded optimally. Control CT scan showed good osteo integration and massive volume stability (>95%).

Abstract:
Skin aging is natural process where renewal of skin cells and collagen production slows down, as well as the weakening of internal support structure and natural protective layer of skin. Several anti-aging therapies are widely used in dealing with aging. Stem cell metabolites are rich in growth factors such as cytokines IL-10, IL-4, EGF, GM-CSF and TGF-β. These cytokines can penetrate skin layer to stimulate the growth of new cells and increase nutrition, accelerate skin metabolism to inhibit premature aging, stimulate skin to produce new proteins, collagen and elastic fibers, also reduce black pigments. Previous research focuses on in vitro and animal study of stem cell metabolites derived from placenta for skin regeneration. This study is an advanced stage by focusing on clinical trial in 30 patients who met the inclusion and exclusion criteria to be applied with stem cell metabolites on their face. Subjects were examined their face conditions by using janus skin analyzer to see markers on their skin and applied stem cell metabolites in their face twice per day, at day and night with single-use doses of three pumping. Evaluation was carried out before and after application of stem cell metabolites using janus in six weeks. The results of janus examination evaluated were spot, pore, roughness, wrinkle, UV acne, UV spot and UV moisture. The percentage of spot, pore, roughness, wrinkle, UV acne and UV spots are decreased, while the percentage of UV moisture is increased in almost all subjects who were evaluated for six weeks. In qualitative, almost 90% subjects are satisfied with the results of the application of stem cell metabolites. The subjects felt that facial wrinkles were reduced, the face was smoother and supple and pigmentation was reduced. It can be concluded that stem cell metabolites formula are effective and efficient in skin regeneration.

Title: Patients derived iPSC and brain organoids in translational psychiatric research
Biography:
Mirolyuba Simeonova Ilieva is a Cell Biologist and has completed her PhD in Bio-Medical Nanotechnology at the Danish Technical University. She is a Research Coordinator in the Patients Centered Laboratory of Translational Psychiatry. She is developing new scientific direction in the Department of Psychiatry, University of Southern Denmark-patients derived iPSC and brain organoids for modeling neurodevelopmental psychiatric disorders.
Abstract:
Since their discovery induced pluripotent stem cells (iPSC) offered a new highway for regenerative medicine and the development of new strategies for disease treatment. On the other hand, iPSC derived from patients with specific pathology gives new perspectives for elucidating intimate mechanisms of the disease and development individualized and more effective treatment. The biggest challenge for psychiatric research at present is the lack of an appropriate link between cellular and molecular findings with the clinical symptoms. An important aspect of understanding the neurobiology of psychiatric disorders is to test the utility of the findings in the diagnostic process, which may establish such findings as biomarkers. Therefore the development of new concepts for disease modeling in the field of psychiatry and the creation of relevant humanized in vitro models as a base for downstream research is of a high need. Brain organoids generated from iPSC recapitulate the dynamics of neurogenesis, cellular variety, and intercellular communication which are affected in neurodevelopmental psychiatric disorders such as autism. They have the ability to recreate the right complexity of the brain. On the cellular, protein and gene expression level, organoids demonstrate a high similarity to the neurodevelopment in vivo and can, therefore, recapitulate early stages of the neurogenesis. Brain organoids represent a new tool for high throughput screening of chemical compounds and move forward the development of individualized drug treatment. Finally, the same platform could be used in these individuals, who are at high risk for the development of psychiatric disorders and elucidate the etiology, based on risk factor genes.

Title: Chitosan physical hydrogels for the regeneration of infarcted myocardium
Biography:
Orianne Domenge has completed her Engineering degree in Chemistry and Process Engineering from CPE Lyon (Higher School of Chemistry, Physics and Electronics) and a Specialization in Biochemistry. She is currently pursuing her PhD in Biomaterials in IMP laboratory (Polymer Materials Engineering) and is working on the development of bio-functionalized polysaccharide patches in order to improve myocardial function after infarction.
Abstract:
Myocardial infarction occurs as a consequence of an obstruction of blood vessels supplying the heart (coronary arteries). This leads to the death of myocardial cells (cardiomyocytes). The damaged tissue does not repair spontaneously and scar tissue is formed instead, as the mature contracting cardiac cells have limited capacity to proliferate. The objective of this project is to develop bio-functionalized hydrogel patches that will allow regeneration and functional recovery of the cardiac muscle after myocardial infarction. The strategy is to associate polysaccharide-based hydrogels and trophic factors (proteins), so as to develop cardiac patches capable of inducing beneficial effects for tissue regeneration. More precisely, chitosan physical hydrogels were performed by a NaOH induced-gelation process. Thus, bio functionalized patches were produced varying in composition (polysaccharide concentration, degree of acetylation of chitosan, etc.) and characterized, in particular in terms of mechanical properties, as in the final application, gels will be sutured on the injured tissue. Cardiomyocytes were cultured in vitro on hydrogels to assess the effect of patch composition on the survival and proliferation of cells. Chitosan hydrogel patches were also tested in vivo using a rat model of myocardial infarction. Our results illustrate the beneficial effect of optimized chitosan hydrogel patches in the regeneration and functional recovery of the cardiac tissue after infarction.

Title: Mapping of binding sites on NadA protein of Neisseria meningitidis and blocking its interaction with human brain microvascular endothelial cells
Biography:
Nisseria meningitidis casing cererospinal meningitis utilizes several of its membrane proteins to interact with human Brain Microvascular Endothelial Cells (BMECs). Nisseria adhesin A -NadA an outer membrane protein has been recognized to mediate adhesion of bacteria and evokes strong bactericidal antibodies when used as vaccine candidate. In the present study, binding pockets of NadA (domains) interacting with the receptors of BMECs were mapped using mass spectrometry. In brief, binding of BMECs proteins and recombinant NadA (rNadA) expressed in E. coli M15 cells was determined by western blotting. On membrane tryptic digestion (partial) was performed and the non-interacting rNadA fragments were washed to retain BMEC protein-rNadA peptide complex. Further, mild striping was performed on the complex to isolate the domains of rNadA from BMEC proteins. MALDI-TOF/MS was employed to identify the amino acid sequences of the domains. Next, synthetically produced NadA peptides (37 mer peptides) corresponding to the interacting domains of rNadA were used to capture single domain antibodies (VHH) raised against rNadA through M13K07ΔpIII hyper phage system. At least 96 VHH clones were found to have an affinity for rNadA peptide 1 and 2. Among them 20 clones were tested for blocking the interaction of rNadA with BMEC proteins. However, only two clones of VHH binding to globular domain of rNadA and one clone of VHH binding to coiled coil region were able to block the interaction of rNadA with hBMEC proteins.

Abstract:
Adrenergic chromaffin cells of the adrenal medulla are generated through recruitment of nerve- associated neural crest-derived cells termed Schwann cell precursors (SCPs). The present study evaluates the effect of serotonin precursor (5-HTP) on survival and proliferation of neural crest derived progenitors into chromaffin cells on E13.5 explants derived from C57BL/6 wild type mice. We also investigate whether serotonin (5-HT) enhances neurite outgrowth and proliferation in non differentiated rat pheochromocytoma cells (PC12), which originate from chromaffin cells. Here we report that treatment with serotonin precursors resulted in a significant decrease of proliferating tyrosine hydroxylase positive (TH+) cells in the adrenal gland (AG). In addition, we demonstrated that serotonin enhances neurite outgrowth in non differentiated cells. The preliminary data indicate the potential of serotonin to function as a new molecular target for neural crest-derived tumors as pheochromocytoma.
