Abstract
Regenerative medicine is the branch of medicine that effectively uses stem cell therapy and tissue engineering strategies to guide the healing or replacement of damaged tissues or organs. A crucial element is undoubtedly the biomaterial that guides biological events to restore tissue continuity. The polymers, natural or synthetic, find wide application thanks to their great adaptability. In fact, they can be used as principal components, coatings or vehicles to functionalize several biomaterials. There are many leading centers for the research and development of biomaterials in Italy. The aim of this review is to provide an overview of the current state of the art on polymer research for regenerative medicine purposes. The last five years of scientific production of the main Italian research centers has been screened to analyze the current advancement in tissue engineering in order to highlight inputs for the development of novel biomaterials and strategies.

Abstract
The aim of this paper is to provide an overview of the results of the research activity carried out in our laboratories, over the last 10 years, in relation to the development of strategies for the production of biomimetic and bioactive scaffolds for myocardial tissue engineering. Biomimetic and bioactive polymeric scaffolds for cardiac regeneration were designed and manufactured in our laboratories and their morphological, physicochemical, mechanical and biological properties were investigated by different techniques, such as scanning electron microscopy, infrared chemical imaging, swelling test, in vitro degradation assessment, dynamic mechanical analysis, in vitro and in vivo biological tests. Biomimetic scaffolds, able to favor tissue regeneration by mimicking nature, were engineered by different strategies, comprising: (i) the imitation of the composition and interactions among components of the natural extracellular matrix (ECM), by mixing of proteins and polysaccharides; (ii) the material surface modification, using both traditional and innovative techniques, such as molecular imprinting; (iii) the incorporation and release of specific active agents and (iv) the production of scaffolds with a microarchitecture similar to that of native ECM. All the developed strategies were found to be effective in creating materials able to influence cellular behavior and therefore to favor the process of new tissue formation. In particular, the approach based on the combination of different strategies aimed at creating a system capable of communicating with the cells and promoting specific cellular responses, as the ECM does, has appeared particularly promising, in view to favor the formation of a tissue equivalent to the cardiac one.

Effects of a collagen hyaluronic acid silk-fibroin patch with the electroconductive element polyaniline on left ventricular remodeling in an infarct heart model. J Biomed Mater Res B Appl Biomater 2022; 110:1651-1666.

Abstract
Biodegradable cardiac patches have been able to induce improvement in left ventricular (LV) remodeling. A novel scaffold patch made with collagen and silk-fibroin (COL-SF) was further associated to polyaniline (PANi) to increase conductivity. Thus, this study investigated the safety of the association of PANi to a patch, and the improvement in LV remodeling in a myocardial infarct (MI) rat model. Wistar rats underwent MI induction. MI was confirmed with echocardiographic and after 2 weeks, animals (n = 10/group) were randomized into: (a) COL-SF hyaluronic acid patch, (b) PANi hyaluronic acid patch, (c) MI Control (just repeat thoracotomy). Healthy animals were also followed. Echocardiography was performed at pre-treatment, and at 2-, 4-, and 8-weeks post-treatment. Hearts underwent hemodynamic evaluation on Langendorff apparatus and histology for LV thickness and percent of infarct size. Liver, kidneys, and blood samples were evaluated for biochemical, hematological, oxidative stress, and histology. There was a tendency of lower %infarct size in patched animals. LV thickness was higher in the patched animals than controls. Functional echocardiographic indices %Fractional shortening and %LV ejection fraction decreased in the MI control group, but not in the patched animals. PANi presented higher %LVEF versus MI control. PANi presented higher liver transaminases; no morphological changes were observed in histology. Elevation of antioxidant markers was observed. COL-SF and PANi patches were able to induce better remodeling features compared to MI controls on %infarct size and LV thickness and have not presented echocardiographic worsening. Polyaniline may present a slight improvement on LV remodeling, despite associated to signs of hepatotoxicity and pro-oxidant effect.

Abstract
Cardiac regeneration aims to reconstruct the heart contractile mass, preventing the organ from a progressive functional deterioration, by delivering pro-regenerative cells, drugs, or growth factors to the site of injury. In recent years, scientific research focused the attention on tissue engineering for the regeneration of cardiac infarct tissue, and biomaterials able to anatomically and physiologically adapt to the heart muscle have been proposed as valuable tools for this purpose, providing the cells with the stimuli necessary to initiate a complete regenerative process. An ideal biomaterial for cardiac tissue regeneration should have a positive influence on the biomechanical, biochemical, and biological properties of tissues and cells; perfectly reflect the morphology and functionality of the native myocardium; and be mechanically stable, with a suitable thickness. Among others, engineered hydrogels, three-dimensional polymeric systems made from synthetic and natural biomaterials, have attracted much interest for cardiac post-infarction therapy. In addition, biocompatible nanosystems, and polymeric nanoparticles in particular, have been explored in preclinical studies as drug delivery and tissue engineering platforms for the treatment of cardiovascular diseases. This review focused on the most employed natural and synthetic biomaterials in cardiac regeneration, paying particular attention to the contribution of Italian research groups in this field, the fabrication techniques, and the current status of the clinical trials.

Abstract
Background Tissue engineering, which involves the selection of scaffold materials, presents a new therapeutic strategy for damaged tissues or organs. Scaffold design based on blends of proteins and polysaccharides, as mimicry of the native extracellular matrix, has recently become a valuable strategy for tissue engineering. Objective This study aimed to construct composite hydrogels based on natural polymers for tissue engineering. Methods Composite hydrogels based on blends of gelatin with a polysaccharide component (chitosan or alginate) were produced and subsequently enzyme crosslinked. The other three hydrogels, chitosan hydrogel, sodium alginate hydrogel, and microbial transglutaminase-crosslinked gelatin (mTG/GA) hydrogel were also prepared. All hydrogels were evaluated for in vitro degradation property, swelling capacity, and mechanical property. Rat adipose-derived stromal stem cells (ADSCs) were isolated and seeded on (or embedded into) the above-mentioned hydrogels. The morphological features of ADSCs were observed and recorded. The effects of the hydrogels on ADSC survival and adhesion were investigated by immunofluorescence staining. Cell proliferation was tested by thiazolyl blue tetrazolium bromide (MTT) assay. Results Cell viability assay results showed that the five hydrogels are not cytotoxic. The mTG/GA and its composite hydrogels showed higher compressive moduli than the single-component chitosan and alginate hydrogels. MTT assay results showed that ADSCs proliferated better on the composite hydrogels than on the chitosan and alginate hydrogels. Light microscope observation and cell cytoskeleton staining showed that hydrogel strength had obvious effects on cell growth and adhesion. The ADSCs seeded on chitosan and alginate hydrogels plunged into the hydrogels and could not stretch out due to the low strength of the hydrogel, whereas cells seeded on composite hydrogels with higher elastic modulus, could spread out, and grew in size. Conclusion The gelatin-polysaccharide composite hydrogels could serve as attractive biomaterials for tissue engineering due to their easy preparation and favorable biophysical properties.

Abstract
Poor mechanical performances severely limit the application of hydrogels in vivo; for example, it is difficult to perform a very common suturing operation on hydrogels during surgery. There is a growing demand to improve the mechanical properties of hydrogels for broadening their clinical applications. Natural polyphenols can match the potential toughening sites in our previously reported PEG-lysozyme (LZM) hydrogel because polyphenols have unique structural units including a hydroxyl group and an aromatic ring that can interact with PEG via hydrogen bonding and form hydrophobic interactions with LZM. By utilizing polyphenols as noncovalent crosslinkers, the resultant PEG-LZM-polyphenol hydrogel presents super toughness and high elasticity in comparison to pristine PEG-LZM with no obvious changes in the initial shape, and it can even withstand the high pressure from sutures. At the same time, the mechanical properties could be widely adjusted by varying the polyphenol concentration. Interestingly, the PEG-LZM-polyphenol hydrogel has a higher water content than other polyphenol-toughened hydrogels, which may better meet the clinical needs for hydrogel materials. Besides, the introduction of polyphenols endows the hydrogel with improved antibacterial and anti-inflammatory abilities. Finally, the PEG-LZM-polyphenol (tannic acid) hydrogel was demonstrated to successfully patch a rabbit myocardial defect by suturing for 4 weeks and improve the wound healing and heart function recovery compared to autologous muscle patches.
