Title
Microvalve bioprinting as a biofabrication tool to decipher tumor and endothelial cell crosstalk: Application to a simplified glioblastoma model

AbstractBioprinting technologies are powerful new bioengineering tools that can spatially reproduce multiple microenvironmental cues in a highly controlled, tunable, and precise manner. In this study, microvalve bioprinting technology was successfully used to print in close proximity endothelial and tumor cells at higher concentrations than previously thought possible, while preserving their viability. We propose that the resulting multicellular models, bioprinted in a controlled extracellular matrix microenvironment, are well-suited to study endothelial and cancer cell crosstalk within a cancer niche. As proof of concept, microvalve bioprinting was applied to the bioengineering of a simplified glioblastoma model in which biological processes involved in tumor expansion, such as tumor cell invasion patterns, cell proliferation, and senescence could be easily visualized and quantified. In this model, U251 glioblastoma cells and primary human umbilical vein endothelial cells (HUVECs) exhibited good printability and high viability after printing. U251 cells formed physiologically relevant clusters and invasion margins, while HUVECs generated vascular-like networks when primary fibroblasts were added to the model. An oxidative stress mimicking the one encountered within a tumor microenvironment during radiotherapy or genotoxic chemotherapy was shown to both diminish endothelial cells proliferation and to increase their senescence. Results also suggested that stressed glioblastoma cells may alter normal endothelial cell proliferation but not impact their senescence. This data demonstrates the potential of microvalve bioprinting to fabricate in vitro models that can help decipher endothelial and tumor cell crosstalk, within controlled and modulable microenvironments, and can then be used to address critical questions in the context of cancer recurrence.

AbstractWhen considering regenerative approaches, the efficient creation of a functional vasculature, that can support the metabolic needs of bioengineered tissues, is essential for their survival after implantation. However, it is widely recognized that the post-implantation microenvironment of the engineered tissues is often hypoxic due to insufficient vascularization, resulting in ischemia injury and necrosis. This is one of the main limitations of current tissue engineering applications aiming at replacing significant tissue volumes. Here, we have explored the use of a new biomaterial, the cell-assembled extracellular matrix (CAM), as a biopaper to biofabricate a vascular system. CAM sheets are a unique, fully biological and fully human material that has already shown stable long-term implantation in humans. We demonstrated, for the first time, the use of this unprocessed human ECM as a microperforated biopaper. Using microvalve dispensing bioprinting, concentrated human endothelial cells (30 millions ml−1) were deposited in a controlled geometry in CAM sheets and cocultured with HSFs. Following multilayer assembly, thick ECM-based constructs fused and supported the survival and maturation of capillary-like structures for up to 26 d of culture. Following 3 weeks of subcutaneous implantation in a mice model, constructs showed limited degradative response and the pre-formed vasculature successfully connected with the host circulatory system to establish active perfusion.This mechanically resilient tissue equivalent has great potential for the creation of more complex implantable tissues, where rapid anastomosis is sine qua non for cell survival and efficient tissue integration.

AbstractThanks to its biological properties, the human amniotic membrane (HAM) combined with a bone substitute could be a single-step surgical alternative to the two-step Masquelet induced membrane (IM) technique for regeneration of critical bone defects. However, no study has directly compared these two membranes. We first designed a 3D-printed scaffold using calcium phosphate cement (CPC). We assessed its suitability in vitro to support human bone marrow mesenchymal stromal cells (hBMSCs) attachment and osteodifferentiation. We then performed a rat femoral critical size defect to compare the two-step IM technique with a single-step approach using the HAM. Five conditions were compared. Group 1 was left empty. Group 2 received the CPC scaffold loaded with rh-BMP2 (CPC/BMP2). Group 3 and 4 received the CPC/BMP2 scaffold covered with lyophilized or decellularized/lyophilized HAM. Group 5 underwent a two- step induced membrane procedure with insertion of a polymethylmethacrylate (PMMA) spacer followed by, after 4 weeks, its replacement with the CPC/BMP2 scaffold wrapped in the IM. Micro-CT and histomorphometric analysis were performed after six weeks. Results showed that the CPC scaffold supported the proliferation and osteodifferentiation of hBMSCs in vitro. In vivo, the CPC/BMP2 scaffold very efficiently induced bone formation and led to satisfactory healing of the femoral defect, in a single-step, without autograft or the need for any membrane covering. In this study, there was no difference between the two-step induced membrane procedure and a single step approach. However, the results indicated that none of the tested membranes further enhanced bone healing compared to the CPC/BMP2 group.

AbstractThe field of bioprinting has shown a tremendous development in recent years, focusing on the development of advanced in vitro models and on regeneration approaches. In this scope, the lack of suitable biomaterials that can be efficiently formulated as printable bioinks, while supporting specific cellular events, is currently considered as one of the main limitations in the field. Indeed, extracellular matrix (ECM)-derived biomaterials formulated to enable printability and support cellular response, for instance via integrin binding, are eagerly awaited in the field of bioprinting. Several bioactive laminin sequences, including peptides such as YIGSR and IKVAV, have been identified to promote endothelial cell attachment and/or neurite outgrowth and guidance, respectively. Here, we show the development of two distinct bioinks, designed to foster vasculogenesis or neurogenesis, based on methacrylated collagen and hyaluronic acid (CollMA and HAMA, respectively), both relevant ECM-derived polymers, and on their combination with cysteine-flanked laminin-derived peptides. Using this strategy, it was possible to optimize the bioink printability, by tuning CollMA and HAMA concentration and ratio, and modulate their bioactivity, through adjustments in the cell-active peptide sequence spatial density, without compromising cell viability. We demonstrated that cell-specific bioinks could be customized for the bioprinting of both human umbilical vein cord endothelial cells (HUVECs) or adult rat sensory neurons from the dorsal root ganglia, and could stimulate both vasculogenesis and neurite outgrowth, respectively. This approach holds great potential as it can be tailored to other cellular models, due to its inherent capacity to accommodate different peptide compositions and to generate complex peptide mixtures and/or gradients.
