Article Synopsis
  • Collagen anisotropy provides important structural cues that influence how cells behave in tissue engineering, but traditional 3D printing methods often fail to create scaffolds with this property.
  • This study introduced a 4D printing technique combining extrusion-based printing with magnetic alignment to create collagen scaffolds that have a high degree of anisotropy.
  • Results showed that while adjusting materials and printing conditions improved collagen alignment, it sometimes compromised print fidelity; nevertheless, scaffolds successfully guided human mesenchymal stem cells towards tendon or ligament-like differentiation, highlighting their potential in musculoskeletal tissue engineering.

Biomass is a valuable renewable energy adapted as an alternative to traditional fossil fuels. Apart from fuels, biomass is synthesized into highly valuable products that are used in various forms including biofuels, biochemical, bioproducts, packing material, and find practice in pharmaceutical, cosmetics, and nutraceuticals industries. Particularly, microalgae a third-generation feedstock known for its rich carbon content possesses protein lipids and carbohydrates produces a variety of green products such as bioethanol, biohydrogen, biodiesel, and biomethane, and also fixes carbon emission to a certain amount in the atmosphere.

Collagen-based scaffolds have been widely used in tissue engineering. The alignment of collagen fibers and the degree of crosslinking in engineering tissue scaffolds significantly affect cell activity and scaffold stability. Changes in microarchitecture and crosslinking degree also impact the mechanical properties of collagen scaffolds.

Carotenoids are the natural pigments available in nature and exhibit different colors such as yellow, red, and orange. These are a class of phytonutrients that have anti-cancer, anti-inflammatory, anti-oxidant, immune-modulatory, and anti-aging properties. These were used in food, pharmaceutical, nutraceutical, and cosmetic industries.
