Here, we demonstrate how the proposed technique may be used to establish a well-tailored, anisotropic microenvironment that promotes myogenic differentiation of human skeletal muscle–derived pericytes (hPeri). Using high-resolution mass spectrometry–based proteomics with the integration of literature-derived signaling networks, we uncovered that (i) a 3D biomimetic matrix environment (PEG-fibrinogen) confers a less mitogenic microenvironment compared to standard 2D cultures, favoring the formation of contractile-competent bundles of pericyte-derived myotubes in an anchoring-independent 3D state and (ii) the RoWS method promotes an upregulation of muscle matrix structural protein besides increasing contractile machinery proteins with respect to 3D bulk cultures. Finally, in vivo investigations demonstrate that the 3D-biofabricated myo-substitute is fully compatible with the host ablated muscular tissue, exhibiting myo-substitute engraftment and muscle regeneration in a mouse model of VML.

By employing a multiscale approach that combined first-principles calculations, molecular dynamics simulations, and kinetic Monte Carlo methods, the relationship between LBL morphology engineering and carrier mobility in donor/acceptor (PM6/L8-BO) thin films is elucidated. During solvent evaporation, the order of solid-phase formation in LBL films was top surface, bottom region, and then the middle region. The early solid precipitation from precursor solutions was acceptor, resulting in a well-ordered molecular arrangement and reducing energy disorder of acceptor LUMO levels. Furthermore, the difference in energy disorders between the A/D blend region and the pure A or D domains enabled LBL morphology engineering to balance electron and hole mobilities, thereby mitigating charge accumulation and recombination.

In the model of the orthotopic CRC, AIE-Pep NPs can precisely localize <i>F. nucleatum</i> around CRC. Moreover, AIE-Pep NPs demonstrated a limit of detection (LOD) of 82.97 CFU/mL for <i>F. nucleatum</i>, which could significantly differentiate the feces of CRC mice from those of normal mice.
