Abstract

To create bioartificial organ and tissue substitutes using the tissue engineering (TE) paradigm, engineering and life sciences tools are combined. These bioartificial substitutes can then be used in regenerative medicine, pharmaceutical, diagnostic, and basic research to elucidate fundamental facets of cell functions in vivo or to pinpoint mechanisms underlying ageing processes and the onset and progression of disease. Interactions between various cell types and the extracellular matrix, whose makeup changes depending on the tissue, level of maturity, and health circumstances, are made possible by the intricate three-dimensional (3D) milieu in which cells are structured in vivo.Overcoming the well-known limitations of organ transplantation, TE seeks to trigger tissue-specific regeneration mechanisms (i.e., donor shortage, need of immunosuppressive therapy). In vitro models of healthy or sick tissues and organs that may be used for drug testing, the assessment of novel therapeutics, and the exploration of the intricate processes governing the genesis and progression of illness have recently been proposed using TE methods. These models not only have a strong scientific potential but also have certain advantages in terms of moral and financial matters.

Introduction

The traditional TE paradigm entails the fusion of live cells with a biological replacement or a three-dimensional living construct that is structurally, mechanically, and functionally equivalent to a tissue. Researchers have developed high expertise in cell manipulation, materials science, and bioengineering for the design of extremely complex biomimetic tissue substitutes for reparative and regenerative purposes [1].

Cells may interact with one another and the surrounding ECM thanks to the intricate structure of in vivo tissue architecture. In order to allow cells to attach, disseminate, proliferate, differentiate, mature, and make ECM similarly to what they do in vivo, the scaffold in an engineered in vitro model must be built to precisely reproduce in vitro the architecture of the original tissue, i.e., its ECM framework. Studies in mechanobiology have emphasised the significance of the mechanical characteristics of the scaffold in appropriately guiding cell activity. Ceramics and their composites are frequently utilised in the TE of hard tissues due to their high stiffness and load-bearing qualities, whereas polymers are mostly used in the engineering of soft tissues [2].

The design and continuous growth of a tissue-engineered model provide a difficulty in the selection of the best suitable cell source. In reality, the capacity to create tissue-specific cellular phenotypes that may accurately mimic normal or damaged natural tissues in vitro is essential for the establishment of realistic in vitro tissue/organ models. Additionally, to ensure a 3D duplicate of the functional unit of the tissue that is physiologically relevant, the amount of cells that will be included in the model should be carefully examined. These cells resemble pluripotent ESCs in their traits and can develop into distinct phenotypes in specific situations. Additionally, iPSCs can be extracted from individuals who have a particular pathology, enabling the modelling of the illness in vitro and the investigation of the processes behind its genesis and progression. The use of patient-derived iPSC lines as cellular assays for the testing of novel drugs and safety evaluations opens the door to a customised approach that can change depending on the patient's pathology [3].

The existence of key chemical signals that govern cell activity is ensured by the in vivo environment, while vascularization enables nutrition delivery and waste elimination. In order to properly mimic morphogenetic processes, molecular variables affecting cellular division, shape, spreading, proliferation, death, and secretion of ECM components must be present.

A precise reproduction of the in vivo environment in vitro in terms of both architectural and mechanical qualities is essential since the three-dimensional cell surrounding environment plays a synergistic role in directing cell destiny and behaviour. Furthermore, a crucial component of the long-term cultivation of any type of cell is the creation of a biomimetic environment. Due to the complexity of human organs and tissues and the difficulty in accurately simulating them at various ageing and health stages in all mechanical, topographical, and chemical aspects, as well as in the set of physiological cues specific to their environment, such an objective is difficult to achieve. Combining recent developments in material engineering, microfabrication methods, and microfluidics is becoming increasingly important in this situation [4].

Furthermore, as they enable the creation of more repeatable scaffolds through a highly regulated procedure, emerging advanced scaffold manufacturing technologies are piqueing an increasing amount of attention. These include effective pore size and connectivity management, which helps with gas diffusion, nutrient delivery, and waste elimination and causes the constructions to become somewhat vascularized, resembling native tissues.
