“…Some studies pointed to physical attractiveness as the main body-related concern, shown to be directly associated with mental health, being depression and anxiety the two most prevalent mental disorders ( Heidari et al, 2015 ; Tsaras et al, 2018 ). Therefore, breast reconstruction is usually the following medical procedure in order to recover the breast shape and volume ( Rocco et al, 2016 ; Calvo-Gallego et al, 2020 ) and, hence, improve the psychological state of the woman ( Combellack et al, 2016 ; Visscher et al, 2017 ; Chae et al, 2018 ; Rocco et al, 2019 ).…”

“…Besides the cancer treatment, breast reconstruction gained the spotlight for the efforts over the post-surgical quality of life improvement ( Na et al, 2019 ), with a positive impact on patient’s psycho-social outcomes ( O’Halloran N. A. et al, 2018 ; Calvo-Gallego et al, 2020 ). To mitigate the effects of mastectomy or for aesthetic purposes, the use of mammary prostheses is a worldwide reality, especially in western countries.…”

Female breast cancer was the most prevalent cancer worldwide in 2020, according to the Global Cancer Observatory. As a prophylactic measure or as a treatment, mastectomy and lumpectomy are often performed at women. Following these surgeries, women normally do a breast reconstruction to minimize the impact on their physical appearance and, hence, on their mental health, associated with self-image issues. Nowadays, breast reconstruction is based on autologous tissues or implants, which both have disadvantages, such as volume loss over time or capsular contracture, respectively. Tissue engineering and regenerative medicine can bring better solutions and overcome these current limitations. Even though more knowledge needs to be acquired, the combination of biomaterial scaffolds and autologous cells appears to be a promising approach for breast reconstruction. With the growth and improvement of additive manufacturing, three dimensional (3D) printing has been demonstrating a lot of potential to produce complex scaffolds with high resolution. Natural and synthetic materials have been studied in this context and seeded mainly with adipose derived stem cells (ADSCs) since they have a high capability of differentiation. The scaffold must mimic the environment of the extracellular matrix (ECM) of the native tissue, being a structural support for cells to adhere, proliferate and migrate. Hydrogels (e.g., gelatin, alginate, collagen, and fibrin) have been a biomaterial widely studied for this purpose since their matrix resembles the natural ECM of the native tissues. A powerful tool that can be used in parallel with experimental techniques is finite element (FE) modeling, which can aid the measurement of mechanical properties of either breast tissues or scaffolds. FE models may help in the simulation of the whole breast or scaffold under different conditions, predicting what might happen in real life. Therefore, this review gives an overall summary concerning the human breast, specifically its mechanical properties using experimental and FE analysis, and the tissue engineering approaches to regenerate this particular tissue, along with FE models.

“…This alternative protocol has been previously published and tested for other tissues such as cartilage and adipose tissue. [6][7][8] The main objectives of this work are: (1) to show that this alternative protocol can be used to characterize the stress relaxation in distraction of bone transport callus; (2) to show its advantages in the interpretation of the data; and (3) to study the evolution of the viscoelastic properties of bone transport callus with TEFO.…”

Callus tissue exhibits a viscoelastic behavior that has a strong influence on the distribution of stresses and their evolution with time and, thus, it can affect tissue differentiation during distraction procedures. For this reason, a deep knowledge of that viscoelastic behavior can be very useful to improve current protocols of bone distraction and bone transport. Monitoring stress relaxation of the callus during distraction osteogenesis allows characterizing its viscoelastic behavior. Different procedures have been used in the literature to fit the response of a given viscoelastic model to the force relaxation curve. However, these procedures do not ensure the uniqueness of that fit, which is of the utmost importance for statistical purposes. This work uses a fitting procedure already validated for other tissues that ensures that uniqueness. Very importantly too, the procedure presented here allows obtaining more information from the stress relaxation tests, distinguishing relaxation in different time scales, which provides a deeper insight into the viscoelastic behavior and its evolution over time. As it was observed in the results, relaxation is faster at the first days after osteotomy and becomes slower and more gradual with time. This fact can be directly linked to the temporal evolution of the callus composition (water, organic phase, and mineral content) and also to the progression of tissue differentiation, with a prevalence of hard tissues as time passes.
