Artificial assembly of mature tissues in vitro is challenging from many viewpoints. Therefore, production of intermediate building blocks - cell spheroids expected to be a viable alternative. The purpose of this research is to develop a biomimetic system for scale up maintenance of spheroids in vitro, and to confirm basic performance of the device. The system consists of a 3D culture unit and a medium perfusion unit. The 3D culture unit is dedicated for spheroid culture without using scaffolds, eliminating concerns about biocompatibility of artificial materials. our culture vessel allows easy disassembly and tissue extraction, as well as the resulting tissue can be formed into an any desirable shape. The spheroids are cultured in a sealed environment and their life are sustained by hollow fiber perfusion fluidics. We confirmed by visual and by microscopic examination that no contamination did occur before and after spheroid inoculation. Moreover, we confirmed growth and fusion between cells when C2C12 spheroids were cultured in this system.

Mononuclear non-heme iron enzymes catalyze a wide array of important oxidative transformations. They are correspondingly diverse in both structure and mechanism. Despite significant evolutionary distance, it is becoming increasingly apparent that these enzymes nonetheless illustrate a compelling case of mechanistic convergence the formation of peroxo species bridging metal and substrate.

Intracellular viscosity is a critical microenvironmental factor in various biological systems, and its abnormal increase is closely linked to the progression of many diseases. Therefore, precisely controlling the release of bioactive molecules in high-viscosity regions is vital for understanding disease mechanisms and advancing their diagnosis and treatment. However, viscosity alone cannot directly trigger chemical reactions.

Natural skin receptors use ions as signal carriers, while most of the developed artificial tactile sensors utilize electrons as information carriers. To imitate the biological ionic sensing behavior, here, we present a kind of biomimetic, ionic, and fully passive mechanotransduction mechanism leveraging mechanical modulation of interfacial ionic p-n junction (IPNJ) through microchannels. Sensors based on this mechanism do not rely on an external power supply and can encode external tactile stimuli into highly analogous signal outputs to those of natural skin receptors, in terms of both signal type (i.

Soft microfluidic systems play a pivotal role in personalized medicine, particularly in in vitro diagnostics tools and disease modeling. These systems offer unprecedented precision and versatility, enabling the creation of intricate three-dimensional (3D) tissue models that can closely emulate both physiological and pathophysiological conditions. By leveraging innovative biomaterials and bioinks, soft microfluidic systems can circumvent the current limitations involving the use of polydimethylsiloxane (PDMS), thus facilitating the development of customizable systems capable of sustaining the functions of encapsulated cells and mimicking complex biological microenvironments.
