(Submitter supplied) In response to polarization cues, cultured Caco-2 cells, a human colon adenocarcinoma-derived cell line, form a polarized epithelium resembling normal enterocytes. We investigated potential signaling mechanisms activated by Caco-2 cells that might trigger the genome-wide transcriptional reprogramming that accompanies polarization (Saaf et al, submitted-I). cDNA microarrays were used to compare the transcriptional profile of Caco-2 polarization to the gene expression profiles of normal human colon and colon tumors. more...

(Submitter supplied) CELL CULTURE: The human intestinal epithelial cell line Caco-2 (obtained from Dr. Stanley Falkow, Stanford University) was used to study the genome-wide expression program underlying the transition from cell proliferation to establishment of a polarized epithelial layer. Cells were first grown in sparse culture on plastic p15 dishes to generate a population of "contact naive" cells. These cells were combined and plated at confluency on Costar filter inserts. more...

(Submitter supplied) Fibroblast cells were cultured from human skin, either tumor (basal cell carcinoma) or non-tumor tissue. Cells were propagated for several passages in culture, then switched to low (0.1%) serum conditions for 48 hours prior to mRNA harvest. Reference for all arrays was Stratagene Universal Human Reference RNA. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. more...

(Submitter supplied) Dataset contains samples that are all fibroblast cells that have been cultured from fresh human tissue. Fibroblasts were derived either from tumor (basal cell carcinoma) or non-tumor (control) tissue. Samples were maintained in DMEM, 10% FBS, glutamine, pen/strep and passaged for 4 passages before RNA harvest was performed using Invitrogen FastTrack. Reference channel RNA is the same for each array in the dataset and is Stratagene Universal Reference RNA. more...

(Submitter supplied) Purpose: to determine cellular heterogeneity of the murine colonic epithelium and mesenchyme; Summary: We determined 16 disctinct sub-populations of colonic epithelial and mesenchymal cells. Further we found 3 distinct sub-populations of colonic PdgfraEGFP-positive fibroblasts.

(Submitter supplied) The conducting airway epithelium of the rodent and human lung is underlaid by mesenchymal cells that include vasculature, smooth muscle, fibroblasts and cartilage. The goal of this project is to identify cellular and molecular changes in the mesenchyme after injury to the epithelium by exposure to SO2 and which may participate in repair of the epithelium We used Affymetrix microarray analysis to compare transcripts in tracheal mesenchyme before and after SO2 injury.

(Submitter supplied) The conducting airway epithelium of the rodent and human lung is made up of about equal proportions of ciliated and secretory cells. In addition, in regions where the epithelium is pseudostratfied, ~30% of the epithelium consists of undifferentiated basal cells (BCs). Evidence suggests that these BCs are multipotent stem cells that can self renew over the long term and give rise to both ciliated and secretory lineages. more...

(Submitter supplied) Intestinal stem cells are sequestered into crypts generated during postnatal development in mice. During this timeframe, we investigated the transition of the surrounding mesenchymal niche. Using single cell RNA sequencing, we generated transcriptomic libraries from a combination of whole tissue and transgenically labeled fractions, including GFP+ fractions from PdgfraH2BEGFP and GFP-tDt+ fractions from PdgfraH2BEGFP;Myh11CreERT2;Rosa26tDt+ mice, of the intestinal mesenchyme at varying postnatal and adult stages. more...

(Submitter supplied) Signals from the surrounding niche drive proliferation and suppress differentiation of intestinal stem cells (ISCs) at the bottom of intestinal crypts. Among sub-epithelial support cells, deep sub-cryptal CD81+ PDGFRAlo trophocytes alone sustain ISC functions ex vivo. Here we show that mRNA and chromatin profiles of abundant CD81- PDGFRAlo stromal cells resemble those of trophocytes and that both populations provide crucial canonical Wnt ligands. more...

(Submitter supplied) In silico analysis identified signalling molecules related to Wnt (Wnt1, 2, 5a, 5b, 6, 11, 14, Wisp1, 2, sFRP1 and 2, Dkks 2 and 3) and BMP (BMP1, 4, 5) pathways. Many of these tags matched multiple transcripts in GenBank, while other potential molecules could not be detected because the transcripts either lacked an anchoring enzyme site or the site was immediately adjacent to the polyA+ sequence.

(Submitter supplied) The intestinal epithelium requires trophic factors and signaling gradients to maintain proper positioning of Intestinal Stem Cells (ISC) and proper differentiation of ISCs. Because the underlying mesenchyme is composed of numerous cell types, we utilized both transgenic and antibody methods to isolate specific mesenchymal populations including GFP-hi and GFP-lo cells from the murine transgenic PDGFRAH2BEGFP mouse (Jackson, #007669), endothelial and lymphatic endothelial cells via antibody for CD31+LYVE1- and CD31+LYVE1+, respectively. more...

To explore how closely assembloids resemble the native tissue, we performed the transcriptional profiling of stromal cells from assembloids and epithelial cells from assembloids, organoids, and colon tissue at the single-cell level.
