Project description:Microarray analysis was used to evaluate expression differences from a single donor human bone marrow stromal cells (hBMSCs) as a function of varied polymer-based tissue engineering scaffolds. These scaffolds include polycaprolactone (PCL) nanofibers (PCL_NF), films (PCL_SC), poly D,L-lactic acid (PDLLA) nanofibers (PDLLA_NF), films (PDLLA_SC), tissue culture polystyrene (TCPS) and TCPS with osteogenic supplements (TCPS_OS). The results revealed that scaffold structure was able to significantly affect gene expression, with nanofiber scaffolds inducing similar gene expression patterns to hBMCSs cultured with osteogenic media. A library of scaffolds prepared from polycaprolactone or poly D,L-lactic acid was sythesized and cultured with hBMSCs for 14 days with RNA extracted from cells on Day 1 and Day 14. Gene expression analysis was performed using BRB ArrayTools. SC = spun coat, BNF = big nanofiber, TCPS = tissue culture polystyrene, TCPS+OS = tissue culture polystyrene with osteogenic supplements.

Project description:Development of systems allowing the maintenance of native properties of mesenchymal stromal cells (MSC) is a critical challenge for studying physiological functions of skeletal progenitors, as well as towards cellular therapy and regenerative medicine applications. Conventional stem cell culture in monolayer on plastic dishes (2D) is associated with progressive loss of functionality, likely due to the absence of a biomimetic microenvironment and the selection of adherent populations. Here we demonstrate that 2D MSC expansion can be entirely bypassed by culturing freshly isolated bone marrow cells within the pores of 3D scaffolds in a perfusion-based bioreactor system, followed by enzymatic digestion for cell retrieval. The 3D-perfusion system supported MSC growth while maintaining cells of the hematopoietic lineage, and thus generated a cellular environment mimicking some features of the bone marrow stroma. As compared to 2D-expansion, sorted CD45- cells derived from 3D-perfusion culture after the same time (3 weeks) or a similar extent of proliferation (7-8 doublings) maintained a 4.3-fold higher clonogenicity and exhibited a superior differentiation capacity towards all typical mesenchymal lineages, with similar immunomodulatory function in vitro. Transcriptomic analysis performed on MSC from 5 donors validated the robustness of the process and indicated a reduced inter-donor variability as well as a significant upregulation of multipotency-related gene clusters following 3D-perfusion as compared to 2D expansion. The described system offers a model to study how factors of a 3D engineered niche may regulate MSC function and, by streamlining conventional labor-intensive processes, is prone to automation and scalability within closed bioreactor systems. Nucleated cells were isolated from 5 fresh human bone marrow aspirates by means of red blood cells lyses buffer and then were seeded into a 3D perfusion bioreactor system using a pure hydroxyapatite 3D scaffold and in conventional Petri dishes (2D). After culture for 19 days, cells from both systems were enzymatically retrieved and sorted using anti-CD45-coated magnetic beads. Total RNA was extracted from CD45- cells, QCed and hybridized to Affymetrix microarrays.

Project description:In vitro models of human liver functions are used across a diverse range of applications in preclinical drug development and disease modeling, with particular increasing interest in models that capture facets of liver inflammatory status. This study investigates how the interplay between biophysical and biochemical microenvironment cues influence phenotypic responses, including inflammation signatures, of primary human hepatocytes (PHH) cultured in a commercially available perfused bioreactor. A 3D printing-based alginate microwell system was designed to form thousands of hepatic spheroids in a scalable manner as a comparator 3D culture modality to the bioreactor. Soft, synthetic extracellular matrix (ECM) hydrogel scaffolds with biophysical properties mimicking features of liver were engineered to replace polystyrene scaffolds, and the biochemical microenvironment was modulated with a defined set of growth factors and signaling modulators. The supplemented media significantly increased tissue density, albumin secretion, and CYP3A4 activity but also upregulated inflammatory markers. Basal inflammatory markers were lower for cells maintained in ECM hydrogel scaffolds or spheroid formats than polystyrene scaffolds, while hydrogel scaffolds exhibited the most sensitive response to inflammation as assessed by multiplexed cytokine and RNA-seq analyses. Together, these engineered 3D liver microenvironments provide insights for probing human liver functions and inflammatory response in vitro.

Project description:The liver is the most common site for colorectal cancer (CRC) metastasis and new tissue culture models are needed to study hepatic metastasis from CRC as none of the current models mimic the biological, biochemical and structural characteristics of the metastatic microenvironment. Decellularization provides a novel approach for the study of cancer extracellular matrix (ECM) as decellularized scaffolds retained their tissue-specific features and biological properties. In the present study we created a 3D model of CRC and matched CRC liver metastasis (CRLM) using patient-derived decellularized ECM scaffolds seeded with HT-29 CRC cell line. Here we show increased HT-29 cell proliferation and migration capability when cultured in cancer-derived scaffolds compared to same-patient healthy colon and liver tissues. CRLM scaffolds also induced activation of epithelial-mesenchymal transition (EMT) with cancer cells showing loss of E-cadherin expression and increased Vimentin expression. EMT was confirmed by gene expression profiling, with the most represented biological processes in CRLM-seeded scaffolds involving demethylation, deacethylation, cellular response to stress metabolic processes, response to oxygen level and to starvation. The complex 3D culture environment reduced the HT-29 cell response to anti-CRC drug 5-FU when used at standard IC50 determined in 2D cultures. In conclusion, our 3D culture system with patient-derived tissue-specific decellularized ECM better recapitulates the metastatic microenvironment compared to conventional 2D culture conditions and represents a relevant approach for the study of liver CRC metastasis formation and progression. Transcriptomic analysis was performed comparing the global gene expression profiles of HT29 cells grown on CRLM and HL scaffolds. The transcriptomic profile of each 3D subtype was compared with HT29 cells grown in plastic. Hierarchical clustering analysis revealed that the gene expression signature of recellularized CRLM scaffolds was more comparable to recellularized HL scaffolds, than to HT29 cells grown in 2D. Gene set enrichment analysis (GSEA) of the differently expressed genes (DEG) up-regulated in recellularized CRLM scaffolds compared to HT29 grown in 2D revealed that genes involved in demethylation, deacethylation and metabolic process belong to the most enriched biological pathways in repopulated-CRLM scaffolds. Comparing the DEG between recellularized CRLM scaffolds vs HT29 grown in 2D with a series of a-priori defined gene-set, called Hallmark, we obtained concordant results with the “HYPOXIA” and “EPITHELIAL_MESENCHYMAL_TRANSITION” pathway, enriched in recellularized CRLM, supporting the idea that 3D culture models are the ability to re-create a complex environment in terms of oxygen tension, nutrients, and metabolic gradient, similarly to the in vivo environment.

Project description:To characterize cells cultured in 3D culture system using NanoCulture plates (NCPs) (Scivax) and in 2D culture, we examined gene expression in HT-29 cells on day 1 or day 7 on NCPs or 2D monolayer culture, using DNA microarrays. From our study, tumour cells grown on NCPs were morphologically different from cells in 2D monolayers, and the cells on NCPs actively migrated and aggregated to form multicellular spheroids (MCSs). To characterize this cell migration and intercellular adhesion, we compared gene expression in HT-29 cells on day 1 on NCPs and 2D monolayer culture using DNA microarrays. We could not find any significant difference in gene expression related to cell migration or cell-cell adhesion between cells grown on NCPs and as 2D monolayers on day 1, showing that cells on NCPs migrated and aggregated without any changes in gene expression (3D Day1 vs 2D Day1 2Fold change.xls). We next characterized mature 3D MCSs on NanoCulture plates, by comparing the gene expression profile of MCSs on day 7 and day 1 (3D Day7 vs 3D Day 1 2Fold change.xls). On day 7, we found a statistically significant increase in the expression of genes related to multicellular organization, intercellular signalling and the response to hypoxia. DNA microarray analysis also showed that the expression of genes that have been reported to be target genes for the transcription factor hypoxia-inducible factor 1 (HIF-1) (Ke, Q. & Costa, M. Hypoxia-inducible factor-1 (HIF-1). Mol Pharmacol 70, 1469-1480 (2006); Semenza, G.L. Defining the role of hypoxia-inducible factor 1 in cancer biology and therapeutics. Oncogene 29, 625-634.) was increased on day 7. When compared day 7 with 2D culture cells, the same tendency was observed (3D Day7 vs 2D Day 7 2Fold change.xls). HT-29 cells were maintained routinely as 2D monolayers in a humidified atmosphere of 5% CO2 in air at 37 °C in the growth medium recommended by suppliers. Exponentially growing cells were used in experiments, after trypsinization to detach them from the plates. Viable cells were counted using trypan blue dye-exclusion. For experiments, cells were seeded in 96-well plates at 1×10^4 cells/100 ul of NanoCulture Medium-M (Scivax) in either NCPs (Scivax), or in polystyrene plates for 2D monolayers, for 1 day or 7 days. Cells were collected and used for RNA extraction and DNA microarray analysis.
