In the field of regenerative medicine applied to neurodegenerative diseases, one of the most important challenges is the obtainment of innovative scaffolds aimed at improving the development of new frontiers in stem-cell therapy. In recent years, additive manufacturing techniques have gained more and more relevance proving the great potential of the fabrication of precision 3-D scaffolds. In this review, recent advances in additive manufacturing techniques are presented and discussed, with an overview on stimulus-triggered approaches, such as 3-D Printing and laser-based techniques, and deposition-based approaches. Innovative 3-D bioprinting techniques, which allow the production of cell/molecule-laden scaffolds, are becoming a promising frontier in disease modelling and therapy. In this context, the specific biomaterial, stiffness, precise geometrical patterns, and structural properties are to be considered of great relevance for their subsequent translational applications. Moreover, this work reports numerous recent advances in neural diseases modelling and specifically focuses on pre-clinical and clinical translation for scaffolding technology in multiple neurodegenerative diseases.

State Of Art

Tissue engineering (TE) scaffolds have enormous significance for the possibility of regeneration of complex tissue structures or even whole organs. Three-dimensional (3D) printing techniques allow fabricating TE scaffolds, having an extremely complex structure, in a repeatable and precise manner. Moreover, they enable the easy application of computer-assisted methods to TE scaffold design. The latest additive manufacturing techniques open up opportunities not otherwise available. This study aimed to summarize the state-of-art field of 3D printing techniques in applications for tissue engineering with a focus on the latest advancements. The following topics are discussed: systematics of the available 3D printing techniques applied for TE scaffold fabrication; overview of 3D printable biomaterials and advancements in 3D-printing-assisted tissue engineering.

New Treatment

The incidence of cardiovascular disease (CVD) in adults are increasing worldwide with impaired repair mechanisms, leading to tissue and organ failure. With the current advancements, life expectancy has improved and has led to search for new treatment strategies that improves tissue regeneration. Recently, stem cell therapy and tissue engineering has captured the attention of clinicians, scientists, and patients as alternative treatment options. The overall clinical experience of these suggests that they can be safely used in the right clinical setting. Ultimately, large outcome trials will have to be conducted to assess their efficacy. Clinical trials have to be carefully designed and patient safety must remain the key concern. At the same time, continued basic research is required to understand the underlying mechanism of cell-based therapies and cell tissue interactions. This chapter reviews the evolving paradigm of stem cell therapy and tissue engineering approaches for clinical application and explores its implications.

Epithelial Structure

The airway epithelium is subjected to a lifetime exposure to inhaled particles and pathogens that may lead to the development of a variety of infectious and inflammatory respiratory diseases such as chronic bronchitis, asthma and chronic obstructive pulmonary disease. These disorders are typically associated with changes in the architecture of the airway walls,that range from epithelial structure remodeling to complete denudation of the basement membrane. The repair of injuries and the regeneration of the epithelial structure involve stem and progenitor cells. Although both secretory and basal cells are able to proliferate, only basal cells are recently suggested to represent the stem cell (SC) niche of the airway epithelium in human tracheas and bronchi, but the adult secretory cells lose their regeneration potential compared to the fetal secretory cells. For this reason, researchers are considering other sources for exogenous pluripotent SCs for airway tissue engineering. At present, autologous bone marrow and adipose derived MSCs seem to present the most popular SC type used in laryngotracheal tissue engineering. Extra-fetal derived SCs could represent new alternative cell sources for lung regeneration. Investigations of stem cell therapy for murine lung injuries revealed an excellent regeneration potential of extra-fetal derived cells that integrated into the lung and differentiated into pulmonary lineages after injury. Recurrent airway obstruction disease (RAO) in the horse is one of the only naturally occurring diseases in animals that is comparable to bronchial asthma in humans. The anamnestic and reversible nature of equine RAO is similar to some forms of human asthma suggesting a common immunological basis. Based on similarities between human asthma and equine RAO, we propose to use spontaneously RAO affected horses as an animal model in biomedical research. We describe the isolation, in vitro proliferation capacity and labeling of equine extra-fetal derived cells, and preliminary in vivo results indicating that after local injection, labeled cells could be retrieved by bronchoalveolar lavage from selected pulmonary areas.

Minimal Information

The aging population has contributed to the rapid rise in the global incidence of neurodegenerative diseases. Despite the medical advances, there are no effective treatments for these disorders. Therefore, there is an urgent need for new treatments for these diseases. In this sense, cell therapy has been recognized as the best candidate for treating incurable diseases, such as neurodegenerative disorders. However, the therapeutic use of these cells can be limited by several factors. Thus, there has been a rediscovery that extracellular vesicles, including exosomes, can be alternatively explored in the treatment of these diseases, overcoming the limits of cell-based therapy. In this sense, this review aims to revisit all areas from biology, including biogenesis and the content of exosomes, to biotechnology, proposing the minimal information required to isolate, characterize, and study the content of these vesicles for scientific and/or clinical purposes.
