In the intricate skeletal muscle tissue, the symbiotic relationship between myotubes and their supporting vasculature is pivotal in delivering essential oxygen and nutrients. This study explored the complex interplay between skeletal muscle and endothelial cells in the vascularization of muscle tissue. By harnessing the capabilities of three-dimensional (3D) bioprinting and modeling, we developed a novel approach involving the co-construction of endothelial and muscle cells, followed by their subsequent differentiation. Our findings highlight the importance of the interaction dynamics between these two cell types. Notably, introducing endothelial cells during the advanced phases of muscle differentiation enhanced myotube assembly. Moreover, it stimulated the development of the vascular network, paving the way for the early stages of vascularized skeletal muscle development. The methodology proposed in this study indicates the potential for constructing large-scale, physiologically aligned skeletal muscle. Additionally, it highlights the need for exploring the delicate equilibrium and mutual interactions between muscle and endothelial cells. Based on the multicell-type interaction model, we can predict promising pathways for constructing even more intricate tissues or organs. [GRAPHICS] .

The catalyst layers(CLs) electrode is the key component of the membrane electrode assembly(MEA) in proton exchange membrane fuel cells(PEMFCs). Conventional electrodes for PEMFCs are composed of carbon-supported, ionomer, and Pt nanoparticles, all immersed together and sprayed with a micron-level thickness of CLs. They have a performance trade-off where increasing the Pt loading leads to higher performance of abundant triple-phase boundary areas but increases the electrode cost. Major challenges must be overcome before realizing its wide commercialization. Literature research revealed that it is impossible to achieve performance and durability targets with only high-performance catalysts, so the controllable design of CLs architecture in MEAs for PEMFCs must now be the top priority to meet industry goals. From this perspective, a 3D ordered electrode circumvents this issue with a support-free architecture and ultrathin thickness while reducing noble metal Pt loadings. Herein, we discuss the motivation in-depth and summarize the necessary CLs structural features for designing ultralow Pt loading electrodes. Critical issues that remain in progress for 3D ordered CLs must be studied and characterized. Furthermore, approaches for 3D ordered CLs architecture electrode development, involving material design, structure optimization, preparation technology, and characterization techniques, are summarized and are expected to be next-generation CLs for PEMFCs. Finally, the review concludes with perspectives on possible research directions of CL architecture to address the significant challenges in the future.
