“…409 Simultaneously, the viscosity of the bioresin should prevent cell sedimentation. In a study by Kim et al, 410 cells dispersed in 10% Gel-MA solution with a viscosity of 3 mPa•s eventually sedimented after 1 h without any mixing. However, if the same solution was slowly added in the vat after each layer, cells were homogeneously distributed throughout the printed construct.…”

“…50,416 More recently, glycidyl methacrylate-conjugated silk fibroin (Sil-MA) was synthesized and used in a DLP bioprinter. 410 The mechanical properties of the Sil-MA bioresin were tuned by controlling the concentration (10 -30%), where 30% polymer concentration exhibited very high mechanical strength (910 kPa at break) due to the intrinsic tensile strength of silk fibroin (Figure 39B).…”

Photo-activated materials have found widespread use in biological and medical applications and are playing an increasingly important role in the nascent field of three-dimensional (3D) bioprinting. Light can be used as a trigger to drive the formation or the degradation of chemical bonds, leading to unprecedented spatiotemporal control over a material's chemical, physical, and biological properties. With resolution and construct size ranging from nanometres to centimeters, light-mediated biofabrication allows multicellular and multimaterial approaches. It promises to be a powerful tool to mimic the complex multiscale organization of living tissues including skin, bone, cartilage, muscle, vessels, heart, and liver, among others, with increasing organotypic functionality. With this review, we comprehensively discuss photochemical reactions, photo-activated materials, and their use in state-of-the-art deposition-based (extrusion and droplet) and vat polymerization-based (one-and two-photon) bioprinting. By offering an up-to-date view on these techniques, we identify emerging trends, focusing on both the chemistry and instrument aspects, thereby allowing the readers to select the best-suited approach. Starting with photochemical reactions and photo-activated materials, we then discuss principles, applications, and limitations of each technique. With a critical eye to the most recent achievements, the reader is guided through this exciting, emerging field with special emphasis on cell-laden hydrogel constructs.

“…Гелеобразование фиброина шелка можно индуцировать в водных его растворах высокой температурой, снижением pH, обработкой ультразвуком, замораживанием; описано и его электрогелеобразование с формированием конформации β-структуры, которая физически сшивает и стабилизирует гель [74]. Получена и модификация фиброина шелка метакрилатом [76]. Шелк разлагается in vivo протеолитическими ферментами медленно (обычно в течение года) [77] и обладает хорошими с точки зрения биопечати механическими свойствами [78].…”

“…Этот подход имеет несколько преимуществ перед другими методами сшивки, так как при его использовании легко осуществлять контроль печати, регулируя скорость и степень отверждения получаемой конструкции. Многие природные биоматериалы, такие как желатин [18,19], фиброин шелка [76] и коллаген [114], под действием УФ с длиной волны 365 нм полимеризуются путем акрилирования. Drzewiecki et al продемонстрировали использование фотоотверждения метакриламида коллагена в качестве фибриллообразующих биочернил для изготовления каркасов [114].…”

“…Фотосшивание метакрилата ГК было описано в работе Onofrillo et al при создании скаффолда хряща [19]. Сходным образом был получен и исследован гель на основе метакрилата фиброина шелка (SilMA), который, по мнению авторов, характеризуется биосовместимостью, биоразлагаемостью и имеет подходящую биологическую и механическую прочность [76]. В отличие от полимеризации генипином, при фотоотверждении метакрилата полимеризация одного слоя завершается за 5 минут.…”

3D Bioprinting is a dynamically developing technology for tissue engineering and regenerative medicine. The main advantage of this technique is its ability to reproduce a given scaffold geometry and structure both in terms of the shape of the tissue-engineered construct and the distribution of its components. The key factor in bioprinting is bio ink, a cell-laden biocompatible material that mimics extracellular matrix. To meet all the requirements, the bio ink must include not only the main material, but also other components ensuring cell proliferation, differentiation and scaffold performance as a whole. The purpose of this review is to describe the most common materials applicable in bioprinting, consider their properties, prospects and limitations in cartilage restoration.

Abstract3D printing and bioprinting have become a key component in precision medicine. They have been used toward the fabrication of medical devices with patient‐specific shapes, production of engineered tissues for in vivo regeneration, and preparation of in vitro tissue models used for screening therapeutics. In particular, vat polymerization‐based 3D (bio)printing as a unique strategy enables more sophisticated architectures to be rapidly built. This progress report aims to emphasize the recent advances made in vat polymerization‐based 3D printing and bioprinting, including new biomaterial ink formulations and novel vat polymerization system designs. While some of these approaches have not been utilized toward the combination with biomaterial inks, it is anticipated their rapid translation into biomedical applications.
