Green bioprinting, from the context of merging 3D bioprinting with microalgae cell organization, holds promise for industrial-scale optimization. This study employs spectrophotometric analysis to explore post-bioprinting growth density variation within hybrid hydrogel biomaterial scaffolds. Three biomaterials-Alginic acid sodium salt (ALGINATE), Nanofibrillated Cellulose (NFC)-TEMPO, and CarboxyMethyl (CMC)-are chosen their scaffolding capabilities. Bioink development impact on proliferation morphology are conducted. Chlorella compositions is probed using absorbance measurements, additional assessment shear thinning properties. Notably, NFC exhibits reduced compared CMC. Results reveal that while mono-hydrogel substrates pronounced adhesion inhibit proliferation, alginate fosters increased concentration alongside a slight viscosity rise.

Mesenchymal stem cells (MSCs) play a critical role in cell therapy due to their tissue-mimicking abilities. However, conventional 2D culture conditions often lead the loss of native hypoxic niche, potentially limiting therapeutic efficacy. 3D bioprinting offers method recreate intricate biological environments by integrating with extracellular matrices. Therefore, it is essential adapt printing techniques accurately replicate MSCs' ecological facilitating integration technology into clinical applications. In this study, we optimized capabilities using performed cellular aggregates (PCA) method. We observed that printed matrix creates microenvironment, resulting significant increase level production several paracrine signaling molecules and immunomodulatory factors MSCs. Furthermore, MSCs exhibited enhanced stemness proliferative capacity early stages culture. RNA-seq analysis revealed these changes behavior were associated environment created during procedure By optimizing bioink composition parameters, successfully simulated vivo leading notable improvements MSC characteristics capacity. RNA sequencing further confirmed activation hypoxia pathways, which are crucial for properties. These findings offer valuable insights leveraging MSC-based therapies regenerative medicine.

Abstract The integration of conductive biological materials into in vitro models represents a transformative approach to advancing biomedical research while addressing critical sustainability challenges. Traditional used tissue engineering and disease modeling are often environmentally detrimental, derived from non-renewable resources, limited their ability replicate the dynamic properties native tissues. Conductive bridge this gap by offering unique combination biodegradability, sustainability, functional properties, such as bioelectricity biocompatibility, that essential for mimicking physiological environments. Herein, development current applications biodegradable materials, including advanced polymers polyaniline polypyrrole, carbon-based nanocomposites, renewable biopolymers lignin cellulose, overviewed. These not only reduce ecological footprint but also enable precise simulation electrical signaling tissues, cardiac, neural, muscular systems, thereby enhancing relevance models. Their three-dimensional (3D) constructs, organ-on-chip platforms, bioprinting technologies facilitates patient-specific models, paving way personalized therapeutic diagnostic applications. In addition precision, these align with global efforts implement circular economy principles research, promoting resource efficiency waste reduction. By combining environmental responsibility state-of-the-art functionality, redefining future 3D accelerating innovation regenerative medicine, drug development, fostering sustainable framework scientific discovery.
