Quantitative design of microRNA-responsive mRNA from expression data

ABSTRACT: Limiting expression to target cell types is a longstanding goal in gene therapy, which could be met by sensing endogenous microRNA. However, an unclear association between microRNA expression and activity currently hampers such an approach. Here, we probe this relationship by measuring the stability of synthetic microRNA-responsive 3'UTRs across 10 cell lines in a library format. By systematically addressing biases in microRNA expression data and confounding factors such as microRNA crosstalk, we demonstrate that a straightforward model can quantitatively predict reporter stability purely from expression data. We use this model to design constructs with previously unattainable response patterns across our cell lines. The rules we derive for microRNA expression data selection and processing should apply to microRNA-responsive devices for any environment with available expression data.

High-throughput automated organoid culture via stem-cell aggregation in microcavity arrays

Project description:Stem-cell-derived epithelial organoids are routinely used for the biological and biomedical modelling of tissues. However, the complexity, lack of standardization and quality control of stem cell culture in solid extracellular matrices hampers the routine use of the organoids at industrial scale. Here, we report the fabrication of microengineered cell-culture devices and scalable and automated methods for the suspension culture and real-time analysis of thousands of individual gastrointestinal organoids trapped in microcavity arrays within a polymer-hydrogel substrate. The absence of a solid matrix significantly reduces organoid heterogeneity, as we show for mouse and human gastrointestinal organoids. We used the devices to screen for anticancer drug candidates with patient-derived colorectal cancer organoids, and high-content image-based phenotypic analyses to reveal insights into drug-action mechanisms. The scalable organoid-culture technology should facilitate the use of organoids in drug development and diagnostics.

Comprehensive analysis of the secretome and transcriptome stability from WJ-Mesenchymal Stromal cells throughout GMP-Manufacturing

Project description:Mesenchymal stromal cells (MSCs) hold promise for cell-based therapies due to their ability to stimulate tissue repair and modulate immune responses. Umbilical cord-derived MSC from Wharton’s jelly (WJ), offer advantages such as low immunogenicity and potent immune modulatory effects. However, ensuring consistent quality and safety throughout their manufacturing process remains critical. RNA sequencing (RNA-seq) emerges as a crucial tool for assessing genetic stability and expression dynamics. This study examines the secretome and transcriptome signatures throughout WJ-MSCs Good Manufacturing Practice (GMP) production, focusing in the role of Total RNA or Massive Analysis of cDNA Ends (MACE-Seq)-RNA sequencing. Through comprehensive transcriptomic analysis, we demonstrated the stability of WJ-MSC transcriptome across manufacturing stages. Notably, MACE-Seq enhanced the identification of key expression patterns related to senescence and immunomodulation. These findings highlight the potential of MACE-Seq as a routine quality assessment tool for WJ-MSC-based therapies, ensuring their efficacy and safety in clinical applications. Importantly, MACE-Seq proves valuable for characterizing WJ-MSC products, providing insights unattainable through traditional assays.

COMPARATIVE ANALYSIS OF THE PROTEOME OF KUPFFER CELLS AND MONOCYTES

Project description:Macrophage population in most mammalian organs consists of cells of different origin, with the exception of the central nervous system and the liver, where macrophages of monocytic origin are almost completely absent. The reasons for such distribution and the phenomenon of coexistence of the two separate macrophage lineages with different origin in mammals remain poorly understood. In present study we compared Kupffer cells and monocytes by the immunophenotype, gene expression profile, proteome and pool of mircoRNA. Observed differences do not allow to consider the resident liver macrophages as purely M2 macrophages or monocytes have purely M1 features. Two populations of macrophages of monocytic origin and resident macrophages have fundamentally different roles in maintaining homeostasis. Monocytic macrophages are involved in the regulation of inflammation, and resident macrophages are involved in the regulation of specific organ functions (nitrogen metabolism, complement system protein synthesis). However, if other indicators would be considered as markers of macrophage activity, it is worth noting that Kupffer cells possess some features of M2 macrophages. This is indicated by their expression profile of let-7b/c/d/e miRNAs, a high content of proteins associated with oxidative phosphorylation, as well as an increased level of synthesis of Arg1, IL10.
