Affymetrix Human Gene 2.0 ST Array (hugene20st)
Description
We previously established long-term 3D organoid culture systems for several murine tissues (intestine, stomach, pancreas and liver) as well as human intestine and pancreas. Here, we describe culture conditions to generate long-term 3D culture from human gastric stem cells. The technology can be applied to study the epithelial response to infection with Helicobacter pylori. Human gastric cultures can expand indefinitely in 3D Matrigel. Cultures can be generated from normal tissue, from single sorted stem cells, or from tumor tissue. Organoids maintain many characteristics of the respective tissue in terms of histology, marker expression and euploidy. Organoids from normal tissue express markers of four lineages of the stomach and self-organize in gland and pit-domains. They can be directed to specifically express either lineages of the gastric gland, or the gastric pit by addition of Nicotinamide and withdrawal of Wnt. While gastric pit lineages react marginally to bacterial infection, gastric gland lineages mount a strong inflammatory response. The gastric culture system provides a unique tool to study gastric pathologies.

Description
Multipotent stem cells and their lineage-restricted progeny drive nephron formation within the developing kidney. Validated markers of these early stem/progenitor populations are essential for deciphering their in vivo function and for evaluating their clinical potential for treating adult kidney disease. Here, we document expression of the adult stem cell marker Lgr5 in the developing kidney and assess the stem/progenitor identity of Lgr5+ve cells via in vivo lineage tracing. The appearance and localization of Lgr5+ve cells coincided with that of the S-shaped body around E14. Lgr5 expression remained restricted to cell clusters within developing nephrons in the cortex until P7, when expression was permanently silenced. In vivo lineage tracing identified Lgr5 as a marker of a novel progenitor population within nascent nephrons dedicated to generating the thick ascending limb of Henle's loop and distal convoluted tubule. The Lgr5 surface marker and experimental models described here will be invaluable for deciphering the contribution of early nephron stem cells to developmental defects and for isolating human nephron progenitors as a prerequisite to evaluating their therapeutic potential.

Description
Proliferation of the self-renewing epithelium of the gastric corpus occurs almost exclusively in the isthmus of the glands, from where cells migrate bi-directionally towards pit and base. The isthmus is therefore generally viewed as the stem cell zone. We find that the stem cell marker Troy is expressed at the gland base by a small subpopulation of chief cells. By lineage tracing using a Troy-eGFP-ires-CreERT2 allele, single marked cells are shown to generate entirely labeled gastric units over periods of months. This phenomenon accelerates upon tissue damage. Troy+ chief cells can be cultured to generate long-lived gastric organoids. Troy marks a specific, 'plastic' subset of differentiated chief cells capable of replenishing entire gastric units, essentially serving as a quiescent reserve stem cell.
Publication Title
Differentiated Troy+ chief cells act as reserve stem cells to generate all lineages of the stomach epithelium.

Description
Needle biopsies were performed to obtain liver samples from patients for clinical purposes from patients with Alagille syndrome. A small portion was snap frozen and later used for RNA sequencing analysis. Needle biospies from 5 patients with other liver disorders were included as controls. Overall design: Examination of RNA expression in Alagille patients'' liver samples, compared to other control liver samples (with other chronic liver diseases).

Description
RNA sequencing of control or Notch1-expressing mouse cells co-cultured with control, Jag1WT, or Jag1Ndr-expressing human cells. Deep sequencing and bioinformatical separation of mouse and human reads reveals transcripts specifically regulated in mouse receptor-expressing cells. Overall design: Mouse C2C12 control and C2C12-FLNotch1, and human HEK-293-Flp-In cells (Hansson et al., 2010): HEK293-Flp control (Flp Ctrl), HEK293-Flp-Jag1WT (Flp Jag1+), HEK293-Flp-Jag1Ndr (Flp Jag1Ndr) were used in this experiment. In one 12-well plate, we seeded 3 wells of mouse C2C12 control cells and 3 wells of C2C12-FLN1 cells, with 3.6x105 cells in 1 mL antibiotic-free medium per well. Cells were allowed to settle for 8 hours. C2C12 control and C2C12-FLN1 cells were transfected with pcDNA5 (1.6 ug/well). All transfections were done using Lipofectamine® 2000 (InvitrogenTM, cat. no. 11668-019) with Opti-MEM® I Reduced Serum Medium (Gibco®, cat. no. 31985-062), according to manufacturer's instructions. The following day (18 hours post transfection), 3.6x105 cells in 0.5 mL antibiotic-free medium of Flp Ctrl, Flp Jag1+, or Flp Jag1Ndr cells were added. Cells were co-cultured for 6 hours, then lysed in 350 uL per well Buffer RLT (QIAGEN, cat. no. 79216) with 1% 2-Mercaptoethanol (Sigma-Aldrich®, cat. no. M3148) and stored at -80°C until RNA extraction.

Gene expression profiles from ALDH high cells sorted from expanded adult human pancreatic organoids are more similar to fetal pancreatic tissue and ALDH high cells sorted from expanded fetal human pancreatic organoids than to adult human islets or adult islet-depleted exocrine tissue. Overall design: RNA was isolated from ALDHhi cells sorted from organoids after 7 days expansion derived from human adult pancreatic tissue, ALDHhi cells sorted from organoids after 7 days expansion derived from human fetal pancreatic tissue, primary fetal pancreatic tissue, adult human islets from different donors and adult exocrine (islet-depleted) pancreatic tissue from different donors.

Description
Anaplastic lymphoma kinase (ALK) is expressed in around 60% of glioblastomas and conveys tumorigenic function. Therefore, ALK inhibitory strategies with alectinib were investigated in glioblastoma cells. We demonstrated that alectinib inhibited proliferation and clonogenicity of ALK expressing glioblastoma initiating cells, whereas cells without ALK expression or after ALK depletion via knockdown showed primary resistance against alectinib. The aim of this analysis was to investigate molecular mechanisms of alectinib mediated treatment effects in the ALK expressing S24 cells, which represent a primary glioblastoma cell culture, and after knockdown of ALK.

Description
Undifferentiated and differentiated Keratinocytes (AG1478 treated) were stained with antibody-RNA conjugates to measure protein-based diffrentiation changes in conjunction with single-cell transcriptomics. The cells were crosslinked and stained according to the RAID procedure to allow intracellular immunostaining. Antibodies used in this experiment are (TGM1, NOTCH1, KLK6, JAG1, phospho-RPS6, phospho-FAK). Overall design: Three 384 wells plates for untreated and Three 384 wells plates for AG1478 treated cells were processed for single cell transcriptomics

Description
Cell fixation, permeabilization and antibody staining of could have adverse effects on the quality of single cell transcriptomics data. To assess the effects of the RAID procedure, which includes such steps, we performed a direct comparison of single cell transcriptomics by CELseq2 using unfixed and RAID-processed cells. Quality measures (gene complexity, gene detection rate, average gene expression) were performed using 40000 samples UMI counts per cell. Overall design: Single cells were sorted in 96, wells plates. Per condition (unfixed or RAID) three sets (A,B,C) of 48 cells were processed with the CELseq2 protocol.
