Continuous liquid interface production (CLIP), an additive manufacturing technology, has several unique features that make it a suitable platform for 3DBP of cell-laden scaffolds. However, the feasibility CLIP bioprinting and efficacy of CLIP-bioprinted cell/matrix therapies have not yet been explored. In this work, we demonstrate the utility of CLIP for cell therapy 3DBP with a simple gelatin methacrylate-based resin and anticancer drug-secreting fibroblasts as a model therapy against recurrent glioblastoma. We demonstrate that CLIP enables rapid, consistent production of cell-laden scaffolds, and cells maintain their viability and tumor-killing efficacy in vitro post-printing. Importantly, we proved that bioprinted cells survive longer in vivo than directly injected cells, and that this effect may correspond to better survival outcomes in a mouse model of glioblastoma resection.

The results demonstrate a significantly higher uptake of the targeted AuNCs into MCF-7 cells compared to nontargeted counterparts.

This cytotoxicity can be attributed to multiple factors, including hyperthermia induced by RF irradiation, heat-triggered release of the loaded drug, and the generation of reactive oxygen species (ROS).

Recent advancements in DNA nanotechnology have spurred the development of endogenous stimuli-responsive functional DNA-based nanosystems, enabling controlled release of DNAzyme by internal cues. This mini-review examines recent innovations in the design and development of nanostructured platforms that enable the endogenously triggered release of DNAzymes, along with their catalytic cofactors, primarily for cleavage of a substrate such as messenger RNA (mRNA).

This study introduces a novel approach to boost MSC-exosome production by promoting cell–cell and cell–extracellular matrix (ECM) interactions. Specifically, ECM-integrated MSC spheroid bioprinting technology is employed to optimize exosome secretion, analyzing the effects of spheroid size and ECM composition on exosome production. It is demonstrated that smaller spheroids constructed using MSCs exhibit an enhanced production of exosomes. Additionally, incorporating ECM components, such as fibrin, Matrigel, and collagen, particularly at higher concentrations, further boosts exosome production. Among these, MSC spheroids with a 150 μm diameter and 0.6% w/v collagen integration demonstrate the highest exosome secretion, achieving an 18.4-fold increase compared to traditional 2D culture systems. Furthermore, exosomes derived from ECM-enhanced MSC spheroids exhibit strong efficacy in an in vitro scratch wound assay, underscoring their therapeutic potential.
