Game Changer

Tissue engineering is a booming field of science and technology. The sheer potential it emanates is enough to place all attention on it. Tissue engineering is widely researched for the development of skin substitutes to treat patients with infections or disorders. Commercial skin substitutes provide a promising future to medicine. The availability of different biomaterials for the production of artificial skin has posed many questions regarding the feasibility, usability, and practicality of these products. The articles reviewed discuss tissue engineering as a challenging field and how skin substitutes are vital. Biomaterials and hydrogel studies are found to be a game changer for the field. The functional aspects have been discussed with the physical characteristics for better understanding. Different techniques of printing biological structures by using scaffolds are discussed in detail. Scaffolds provide a very efficient structural composition for the bioprinter to manifest the organ to be printed. Bioink composition and preparation with scientific knowledge make it a very important asset in tissue engineering. The future of regenerative medicine and organ transplantation is expected to be safe within the various aspects of tissue engineering. The vast possibilities it offers is hard to not explore further. Even though the research field has come a long way since the beginning of tissue culture in the 1970s, there are still different challenges to be faced and conquered.

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 objective of this work is to map the main actors within the Brazilian innovation system framework in the field of tissue engineering and bioprinting, and analyze the main conditioners related to entrepreneurship and innovation. While keeping as a backdrop, the history of 3D Biotechnology Solutions startup, its challenges and projects. Tissue engineering is a subcategory of regenerative medicine with the purpose of repairing or substituting, partially or completely, tissues or organs that have been affected by some disease or lesion. The conventional methods used for the production of these biomaterials via tissue engineering do not have the capacity to mimic the reality of native structures in the nano, micro and macro scales, while guaranteeing the reproducibility andscalability ofthematerials. Technologies such as 3D bioprinting or additive manufacturing could change the way that many diseases are treated in the medium term by replacing the damaged tissues with custom bio-similar constructs. Mapping and reflections based on the innovation systems framework contribute to organize stimulus policies, stimulate interaction between actors, identify gaps and technological demands and periodically organize the analysis and expansion of this system in Brazil.

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.

The Right

The promise of regenerative medicine and tissue engineering is founded on the ability to regenerate diseased or damaged tissues and organs into functional tissues and organs or the creation of new tissues and organs altogether. In theory, damaged and diseased tissues and organs can be regenerated or created using different configurations and combinations of extracellular matrix (ECM), cells, and inductive biomolecules. Regenerative medicine and tissue engineering can allow the improvement of patients’ quality of life through availing novel treatment options. The coupling of regenerative medicine and tissue engineering with 3D printing, big data, and computational algorithms is revolutionizing the treatment of patients in a huge way. 3D bioprinting allows the proper placement of cells and ECMs, allowing the recapitulation of native microenvironments of tissues and organs. 3D bioprinting utilizes different bioinks made up of different formulations of ECM/biomaterials, biomolecules, and even cells. The choice of the bioink used during 3D bioprinting is very important as properties such as printability, compatibility, and physical strength influence the final construct printed. The extracellular matrix (ECM) provides both physical and mechanical microenvironment needed by cells to survive and proliferate. Decellularized ECM bioink contains biochemical cues from the original native ECM and also the right proportions of ECM proteins. Different techniques and characterization methods are used to derive bioinks from several tissues and organs and to evaluate their quality. This review discusses the uses of decellularized ECM bioinks and argues that they represent the most biomimetic bioinks available. In addition, we briefly discuss some polymer-based bioinks utilized in 3D bioprinting.

Regenerative medicine is an emerging field that centers on the restoration and regeneration of functional components of damaged tissue. Tissue engineering is an application of regenerative medicine and seeks to create functional tissue components and whole organs. Using 3D printing technologies, native tissue mimics can be created utilizing biomaterials and living cells. Recently, regenerative medicine has begun to employ 3D bioprinting methods to create highly specialized tissue models to improve upon conventional tissue engineering methods. Here, we review the use of 3D bioprinting in the advancement of tissue engineering by describing the process of 3D bioprinting and its advantages over other tissue engineering methods. Materials and techniques in bioprinting are also reviewed, in addition to future clinical applications, challenges, and future directions of the field.
