Special Issue Information

Dear Colleagues,

Conventional treatment for tissue defects includes autograft, allograft, or xenograft tissue transplantation. Although these surgeries have still their place in the therapeutic arsenal, natural and synthetic biocompatible scaffolds have been developed to imitate the original environment of cells, called the extracellular matrix (ECM), which supports and stimulates proliferation and organization. ECM-based biomaterials are derived from decellularized tissues, and have been extensively explored for in situ tissue regeneration because of their similarity with native tissue ECM. Similarly, natural polymers derived from polysaccharides and proteins have excellent biodegradability and biocompatibility, as well as other features mimicking the ECM. However, their relatively poor mechanical properties limit their applications in anatomical sites with mechanical requirement, such as hard tissue regeneration. Thus, they are often combined with synthetic polymers. Synthetic biomaterials are based on degradable synthetic polymers, and are fabricated using various assembly approaches to produce structures with enhanced physical and mechanical properties such as stiffness, degradation, and porosity. One of the advantages of using synthetic biomaterials is the ability to produce patient-specific scaffolds to match the target anatomy, and to fit the required physical and chemical properties of the injured tissue. Synthetic polymers have no immunological concerns and a high degree of processing flexibility, making it possible to program their biodegradation rate, mechanical properties, and microstructure. Additionally, non-resorbable membranes have shown variable results with, adequate biocompatibility and space-making capacity.

This Special Issue will focus on membranes with functions in barrier or guided tissue regeneration, but also as bioactive compartments. Used as cover or conduit, membranes could have (i) a biological origin, including autograft, induced membrane, allograft or xenograft (with or without decellularization process) engineered membrane; or (ii) a synthetic origin, including resorbable and nonresorbable membranes. Experimental and/or clinical approaches will be addressed, as well as membranes used as scaffolds for bioprinting purposes. Papers which improve our understanding of biological or synthetic membrane formation/formulation and their characterization, handling or surgical application/grafting will be highly appreciated.

Critical bone defect repair remains a major medical challenge. Developing biocompatible materials with bone-healing ability is a key field of research, and calcium-deficient apatites (CDA) are appealing bioactive candidates. We previously described a method to cover activated carbon cloths (ACC) with CDA or strontium-doped CDA coatings to generate bone patches. Our previous study in rats revealed that apposition of ACC or ACC/CDA patches on cortical bone defects accelerated bone repair in the short term. This study aimed to analyze in the medium term the reconstruction of cortical bone in the presence of ACC/CDA or ACC/10Sr-CDA patches corresponding to 6 at.% of strontium substitution. It also aimed to examine the behavior of these cloths in the medium and long term, in situ and at distance. Our results at day 26 confirm the particular efficacy of strontium-doped patches on bone reconstruction, leading to new thick bone with high bone quality as quantified by Raman microspectroscopy. At 6 months the biocompatibility and complete osteointegration of these carbon cloths and the absence of micrometric carbon debris, either out of the implantation site or within peripheral organs, was confirmed. These results demonstrate that these composite carbon patches are promising biomaterials to accelerate bone reconstruction. Full article

A preclinical study was performed to investigate the efficacy and safety of a new viral inactivated, devitalized, freeze-dried and gamma-sterilized human umbilical cord amniotic membrane (lhUC-AM) for the treatment of deep scleral and corneal defects with or without perforation. Firstly, lhUC-AM was investigated on experimental deep sclerectomy in rabbit eyes (n = 12) and compared to autograft (n = 4) on cross section histology. Secondly, lhUC-AM was studied on a selected series of uncontrolled cases of corneal defects (n = 18) with or without perforation, in dogs and cats. lhUC-AM tolerance, reconstruction of the deep corneal lesion and recovery of the structural aspect of the tissue were followed post-surgery. In experimental deep sclerectomy, histology showed that the lhUC-AM was well tolerated and degraded completely in 45 days while allowing an overall quality and kinetic of scleral regeneration, similar to autograft. In the clinical situations, lhUC-AM was well tolerated, with ocular inflammatory signs quickly decreasing after surgery. Mean follow-up was 16.40 ± 11.43 months. In 15 out of 18 cases, lhUC-AM allowed ocular surface wound healing. The ocular surface was fully reconstructed three months after surgery. This study suggests a good safety and efficacy profile of lhUC-AM in the treatment of deep corneal or scleral defect in animals. This new tissue should now facilitate the treatment of severe ocular surface diseases in humans. Full article

Biological tissues from various anatomical sources have been utilized for tissue transplantation and have developed into an important source of extracellular scaffolding material for regenerative medicine applications. Tissue scaffolds ideally integrate with host tissue and provide a homeostatic environment for cellular infiltration, growth, differentiation, and tissue resolution. The human amniotic membrane is considered an important source of scaffolding material due to its 3D structural architecture and function and as a source of growth factors and cytokines. This tissue source has been widely studied and used in various areas of tissue repair including intraoral reconstruction, corneal repair, tendon repair, microvascular reconstruction, nerve procedures, burns, and chronic wound treatment. The production of amniotic membrane allografts has not been standardized, resulting in a wide array of amniotic membrane products, including single, dual, and tri-layered products, such as amnion, chorion, amnion–chorion, amnion–amnion, and amnion–chorion–amnion allografts. Since these allografts are not processed using the same methods, they do not necessarily produce the same clinical responses. The aim of this review is to highlight the properties of different human allograft membranes, present the different processing and preservation methods, and discuss their use in tissue engineering and regenerative applications.
