A 3D Cell Culture Organ-on-a-Chip Platform With a Breathable Hemoglobin Analogue Augments and Extends Primary Human Hepatocyte Functions in vitro

remarkable progress in cell culture three-dimensional (3D) technology and organs-on-a-chip has opened doors to recapitulate the complex aspects of human physiology, pathology and drug responses in vitro. Challenges regarding the delivery of oxygen, throughput, multiplexed testing, and experimental complexity which is intended to ensure that the 3D cell culture perfusion of organs-on-a-chip model into routine research tool adopted by academic and industry stakeholders.

To move the field forward, we present a scalable throughput organ-on-a-chip insert a tube system that requires 48 to operate the 3D cell culture models of organ independent statistician. Then, we introduce in-good perfusion to avoid the loss of cell signaling and drug metabolites in an otherwise one-way flow of perfusate. Furthermore, in order to improve the relevance of the model cell culture in 3D in vitro, we address the problem of transport of oxygen by the blood using, for the first time, an analog of hemoglobin breathing to increase gas deliveries cell respiration, as in vivo approximately 98% of the delivery of oxygen to cells occurs through reversible binding hemoglobin.

Next, we show that an increase in cellular metabolic pathways oxygenation shift towards oxidative phosphorylation that contribute to the maintenance of differentiated phenotype in vitro liver. Finally, we show that the activity of the cytochrome family of P450 enzymes of drug metabolism increased and prolonged in hepatocytes human primary cultured in 3D compared with two-dimensional (2D) cell culture gold standard with important consequences for drug metabolism, drug-drug interactions and pharmacokinetic studies in vitro.

Vasculogenesis of Human Dental Pulp Stem Cells Grown in Matrigel with Fully Defined Serum Free Culture Media

Generation of blood vessels is one of the most important challenges in tissue engineering and regeneration. Human cells pulp stem teeth (hDPSCs) are some of the most promising types of stem cells to induce vasculogenesis and angiogenesis because they not only secrete vascular endothelial growth factor (VEGF), but also can differentiate in vitro into both endotheliocytes and pericytes in culture serum-free media.

Additionally, hDPSCs can generate a complete blood vessel that contains both endothelial and mural coating in vivo after transplantation into adult brain. However, many serum-free media used for growth of a supplement containing hDPSCs undisclosed composition. It generates uncertainty as to which component of the appropriate necessary and dumped to the differentiation of vascular hDPSCs, and also block the transfer of basic research findings to clinical cell therapy.

In this work, we designed and tested a new medium that endothelial differentiation to the composition fully defined using standard basal culture medium plus B27 mixture, heparin and growth factors, including VEGF-A165 at different concentrations. We also optimized in vitro Matrigel assay to characterize both hDPSCs ability to differentiate cells of blood vessels and their capacity to produce tubular blood vessel in 3D culture.

Description of serum-free culture medium for the induction of vasculogenesis fully defined using human adult stem cells as a potential highlight relevant innovation for tissue engineering applications. In conclusion, we achieve efficient vasculogenesis start hDPSCs using serum-free culture medium with fully defined composition, which is valid for the purpose of human cell therapy.

Protection of human induced stem cells are pluripotent against shear stresses in suspension culture by Bingham plastic fluid

suspension cultures is an important method used in the industrial preparation of pluripotent stem cells (PSC), for regenerative therapy and drug screening. Generally, suspension culture require agitation to keep the PSC suspended aggregate and to promote mass transfer, but agitation also cause cell damage.

In this study, we investigated the use of Bingham plastic fluid, equipped with a polysaccharide-based polymer, to preserve the PSC of damage to cells in suspension culture. Rheometric analysis shows that the culture medium obtained yield stress and became Bingham plastic fluid, after supplementation with FP003 polymer.

Analysis of growth / death revealed that the formation of aggregates 2 days and 2 days of suspension in a Bingham plastic media improved cell growth and cell death is prevented. After the initial aggregation step, while the strong agitation (120 rpm) of the conventional culture medium resulted in massive cell death, in Bingham plastic fluid we obtain the same growth as normal culture with optimal agitation (90 rpm).

This shows that the Bingham plastic fluid cells are protected from shear stresses in suspension culture and can be used to increase their resilience when developing large scale. This article is protected by copyright. All rights reserved.

Co-Culture System Analysis Enteroids / Colonoids with innate Immune Cells

enteroids human intestine derived from adult stem cells offer the relevant ex vivo system for studying the biological process of the human gut. They create mobile and functional features of the intestinal epithelium of the small intestine (enteroids) or intestine (colonoids) although limited by the lack of relevant cell types that help maintain tissue homeostasis and to respond to external challenges.

In the intestine, innate immune cells interact with the function of epithelial barrier function support, and deploy effector. We have established a co-culture system enteroid / monolayers colonoid and macrophages underlying and polymorphonuclear neutrophils to recapitulate cellular skeleton of human intestinal epithelial niche. Enteroids generated from biopsies or tissue resected from every segment of the intestines of humans and maintained in long-term culture as a three-dimensional structure through supplementation stem cell growth factor. immune cells isolated from human whole blood fresh or frozen peripheral blood mononuclear cells (PBMC).

A 3D Cell Culture Organ-on-a-Chip Platform With a Breathable Hemoglobin Analogue Augments and Extends Primary Human Hepatocyte Functions in vitro

Monocytes from PBMC differentiated into macrophages by cytokine stimulation prior to co-culture. The method is divided into two main components of the model: (1) generate enteroid / monolayers colonoid and isolating immune cells and (2) the assembly enteroid / colonoid-immune cell co-culture with separate apical and basolateral compartment. Co-culture containing macrophages can be maintained for 48 hours while they neutrophils involved, because of their shorter life span, remain viable for 4 hours.

Enteroid co-cultures of immune-activating several outcome measures, including transepithelial resistance, production of cytokines / chemokines, phenotypic analysis of immune cells, immunofluorescence tissue imaging, protein or mRNA expression, antigen or microbial uptake, and other cellular functions. © 2020 Wiley Periodicals LLC.
