Special Issue Information

Dear Colleagues,

In recent years, research on the fabrication and application of living tissues and organs has been widely conducted using 3D culture (three-dimensional culture) techniques. For example, materials such as ECM (extracellular matrix) and synthetic polymers can be microfabricated to provide a favorable environment and scaffold for individual cells. In other words, a culture environment similar to a living organism (in vivo) can be reconstructed in vitro and created using MEMS (micro electro mechanical system) technology. In addition, it has been possible to induce pluripotent cells (ES cells and iPS cells) and tissue stem cells into target 3D models (brain, liver, skin, bone, cornea, cartilage, cancer, etc.) by improving culture methods and conditions. The obtained tissues and organs are expected to be applied in many fields of biomedicine, regenerative therapy, and drug discovery. Here, we call for reports on 'Applications of 3D Cell Culture in Biomedicines' in various fields of biomedicines. Examples of topics of interest include:

  • 3D cultures (culture technology, biomaterials, culture device, culture device design, simulation, etc.).
  • 3D tissue and organs (biomedicine, regenerative therapy, and drug discovery, in vitro, in vivo, ex vivo).

Therefore, this Special Issue seeks to publish high-quality articles, including original research and reviews.

BACKGROUND: Three-dimensional cellular models provide a more comprehensive representation of in vivo cell properties, encompassing physiological characteristics and drug susceptibility. METHODS: Primary hepatocytes were seeded in ultra-low attachment plates to form spheroids, with or without tumoral cells. Spheroid structure, cell proliferation, and apoptosis [...] Read more.
BACKGROUND: Three-dimensional cellular models provide a more comprehensive representation of in vivo cell properties, encompassing physiological characteristics and drug susceptibility. METHODS: Primary hepatocytes were seeded in ultra-low attachment plates to form spheroids, with or without tumoral cells. Spheroid structure, cell proliferation, and apoptosis were analyzed using histological staining techniques. In addition, extracellular vesicles were isolated from conditioned media by differential ultracentrifugation. Spheroids were exposed to cytotoxic drugs, and both spheroid growth and cell death were measured by microscopic imaging and flow cytometry with vital staining, respectively. RESULTS: Concerning spheroid structure, an active outer layer forms a boundary with the media, while the inner core comprises a mass of cell debris. Hepatocyte-formed spheroids release vesicles into the extracellular media, and a decrease in the concentration of vesicles in the culture media can be observed over time. When co-cultured with tumoral cells, a distinct distribution pattern emerges over the primary hepatocytes, resulting in different spheroid conformations. Tumoral cell growth was compromised upon antitumoral drug challenges. CONCLUSION: Treatment of mixed spheroids with different cytotoxic drugs enables the characterization of drug effects on both hepatocytes and tumoral cells, determining drug specificity effects on these cell types.

Biocompatibility testing of materials is carried out in 2D cell cultures or animal models despite serious limitations. 3D skin equivalents are advanced in vitro models for human skin. Silicone has been shown to be noncytotoxic but capable of eliciting an immune response. Our aim was to (1) establish a 3D skin equivalent to (2) assess the proinflammatory properties of silicone. We developed a coculture of keratinocytes and fibroblasts resulting in a 3D skin equivalent with an implant using samples from a breast implant. Samples with and without the silicone implant were studied histologically and immunohistochemically in comparison to native human skin samples. Cytotoxicity was assessed via LDH-assay, and cytokine response was assessed via ELISA. Histologically, our 3D skin equivalents had a four-layered epidermal and a dermal component. The presence of tight junctions was demonstrated in immunofluorescence. The only difference in 3D skin equivalents with implants was an epidermal thinning. Implanting the silicone samples did not cause more cell death, however, an inflammatory cytokine response was triggered. We were able to establish an organotypical 3D skin equivalent with an implant, which can be utilised for studies on biocompatibility of materials. This first integration of silicone into a 3D skin equivalent confirmed previous findings on silicone being non-cell-toxic but capable of exerting a proinflammatory effect. Full article
