3D stem cell spheroids have immense potential for various tissue engineering applications. However, current spheroid fabrication techniques encounter viability issues due to limited oxygen access cells trapped within the core, as well nonspecific differentiation complicated environment following transplantation. In this study, functional are developed using mesenchymal with 2D hetero-nanostructures (HNSs) composed of single-stranded DNA (ssDNA) binding carbon nanotubes (sdCNTs) and gelatin-bind black phosphorus nanosheets (gBPNSs). An osteogenic molecule, dexamethasone (DEX), is further loaded fabricate an sdCNTgBP-DEX HNS. This approach aims establish a multifunctional cell-inductive improved transportation through hollow nanotubes, stimulated growth by phosphate ions supplied from BP oxidation, in situ immunoregulation, osteogenesis induction DEX molecules after implantation. Initial transplantation rat calvarial bone defect shows vivo macrophage shifts M2 phenotype, leading pro-healing microenvironment regeneration. Prolonged implantation demonstrates outstanding neovascularization, osteointegration, new Therefore, these engineered hold great promise repair they allow delivery provide immunoregulative signals all-in-one construct.

Bone tissue engineering (BTE) holds promise for treating bone defects, and 3D-printed porous scaffolds are pivotal regeneration. This study explores the impact of material extrusion 3D printing (ME3DP) process parameters (i.e., layer height temperature) on made polyetherimide (PEI) BTE. The intricate relationships shaping scaffold dimensional accuracy, residual stresses, warpage tendencies were unveiled using comprehensive numerical simulations. Our findings reveal that higher heights enhance stability, especially at lower temperatures, reducing maximum displacements. Consequently, lead to critical values. insight is instrumental in optimizing process, vital precise net shape BTE applications. Furthermore, stresses also revealed a correlation between temperatures increased stresses. These emphasize necessity balancing flow, temperature, quality. Therefore, right balance precision mechanical stability producing high-quality meet requirements.
