Tissue engineering is an important therapeutic strategy to be used in regenerative medicine in the present and in the future. Functional biomaterials research is focused on the development and improvement of scaffolding, which can be used to repair or regenerate an organ or tissue. Scaffolds are one of the crucial factors for tissue engineering. Scaffolds consisting of natural polymers have recently been developed more quickly and have gained more popularity. These include chitosan, a copolymer derived from the alkaline deacetylation of chitin. Expectations for use of these scaffolds are increasing as the knowledge regarding their chemical and biological properties expands, and new biomedical applications are investigated. Due to their different biological properties such as being biocompatible, biodegradable, and bioactive, they have given the pattern for use in tissue engineering for repair and/or regeneration of different tissues including skin, bone, cartilage, nerves, liver, and muscle. In this review, we focus on the intrinsic properties offered by chitosan and its use in tissue engineering, considering it as a promising alternative for regenerative medicine as a bioactive polymer.

Recent Developments

3D bioprinting has the potential to transform the field of regenerative medicine as it enables the precise spatial patterning of biomaterials, cells and biomolecules to produce engineered tissues. Although numerous tissue engineering strategies have been developed for meniscal repair, the field has yet to realize an implant capable of completely regenerating the tissue. This paper first summarized existing meniscal repair strategies, highlighting the importance of engineering biomimetic implants for successful meniscal regeneration. Next, we reviewed how developments in 3D (bio)printing are accelerating the engineering of functional meniscal tissues and the development of implants targeting damaged or diseased menisci. Some of the opportunities and challenges associated with use of 3D bioprinting for meniscal tissue engineering are identified. Finally, we discussed key emerging research areas with the capacity to enhance the bioprinting of meniscal grafts.

The ability to control the interactions between functional biomaterials and biological systems is of great importance for tissue engineering and regenerative medicine. However, the underlying mechanisms defining the interplay between biomaterial properties and the human body are complex. Therefore, a key challenge is to design biomaterials that mimic the in vivo microenvironment. Over millions of years, nature has produced a wide variety of biological materials optimised for distinct functions, ranging from the extracellular matrix (ECM) for structural and biochemical support of cells to the holy lotus with special wettability for self-cleaning effects. Many of these systems found in biology possess unique surface properties recognised to regulate cell behaviour. Integration of such natural surface properties in biomaterials can bring about novel cell responses in vitro and provide greater insights into the processes occurring at the cell-biomaterial interface. Using natural surfaces as templates for bioinspired design can stimulate progress in the field of regenerative medicine, tissue engineering and biomaterials science. This literature review aims to combine the state-of-the-art knowledge in natural and nature-inspired surfaces, with an emphasis on material properties known to affect cell behaviour.

Abstract Three-dimensional (3D) bioprinting is rapidly evolving, offering great potential for manufacturing functional tissue analogs for use in diverse biomedical applications, including regenerative medicine, drug delivery, and disease modeling. Biomaterials used as bioinks in printing processes must meet strict physiochemical and biomechanical requirements to ensure adequate printing fidelity, while closely mimicking the characteristics of the native tissue. To achieve this goal, nanomaterials are increasingly being investigated as a robust tool to functionalize bioink materials. In this review, we discuss the growing role of different nano-biomaterials in engineering functional bioinks for a variety of tissue engineering applications. The development and commercialization of these nanomaterial solutions for 3D bioprinting would be a significant step towards clinical translation of biofabrication.

Poly Caprolactone

: Diseases, trauma, and injuries are highly prevalent conditions that lead to many critical tissue defects. Tissue engineering has great potentials to develop functional scaffolds that mimic natural tissue structures to improve or replace biological functions. In many kinds of technologies, electrospinning has received widespread attention for its outstanding functions, which is capable of producing nanofibre structures similar to the natural extracellular matrix. Amongst, the electrospinning of available biopolymers, poly (caprolactone) (PCL), has shown favorable outcomes for tissue regeneration applications. According to the characteristics of different tissues, PCL can be modified by altering the functional groups or combining with other materials such as synthetic polymers, natural polymers, and metal materials to improve its physicochemical, mechanical, and biological properties, making the electrospun scaffolds meet the requirements of different tissue engineering and regenerative medicine. Moreover, efforts have been made to modify nanofibres with several bioactive substances to provide cells with the necessary chemical cues and a more in vivo like environment. In this review, some recent developments in both the design and utility of electrospun PCL-based scaffolds in the fields of bone, cartilage, skin, tendon, ligament and nerve are highlighted, along with their potential impact on future research and clinical applications.
