Functional heterogeneity of mouse prostate stromal cells revealed by single cell RNA-seq

ABSTRACT: We perform a single cell RNA-seq analysis to investigate the phenotypic and functional heterogeneity of the adult mouse prostate stromal cells. Our analysis identifies three major cell populations representing the smooth muscle cells and two types of fibroblast cells enriched by CD90 and CD34, respectively. The CD90+ stromal cells are in direct contact with the epithelial cells and express plentiful growth factors and genes associated with cell motility, developmental process, and androgen biosynthesis. This suggests that they may regulate epithelial cell survival and growth. The CD34+ stromal cells highly express genes associated with the extracellular matrix and cytokine-mediated signaling pathways, indicating a role in tissue repair and immune responses. The CD34+ stromal cells significantly suppress the luminal differentiation of the basal cells in the organoid culture assay. Our study identifies novel surface markers enabling physical separation of stromal cell subpopulations and generate gene expression profiles that imply their cellular functions.

Functional and transcriptional heterogeneity of human hemopoietic lympho-myeloid progenitors

Project description:Cord blood (CB) samples from normal donors were obtained with informed consent. Fresh CB samples were processed within 18-34h after collection. Mononuclear cells were isolated and CD34+ fraction was separated. CB CD34+ enriched fraction was lineage depleted by staining with purified anti-human CD2, CD3, CD4, CD7, CD8a, CD11b, CD14, CD19, CD20, CD56, CD235a followed by Qdot 605 conjugated goat F(ab')2 anti-mouse IgG (H+L). Cells were also stained with anti-human CD38-FITC, CD45RA-PE or -BV650, CD123-PE Cy7, CD90-biotin, CD34- PerCP and CD10-APC. Finally, cells were incubated with streptavidin-conjugated APC-eF780 and Hoechst 33258 (Invitrogen, final concentration: 1 g/ml). Populations were defined, as follows: HSC - Lin-CD34+CD38-CD90+CD45RA-CD10-, MPP - Lin-CD34+CD38-CD90-CD45RA-CD10-, LMPP - Lin-CD34+CD38-CD90-/loCD45RA+CD10-, MLP - Lin-CD34+CD38-CD90-/loCD45RA+CD10+, GMP - Lin-CD34+CD38+CD123+CD45RA+CD10-, CMP - Lin-CD34+CD38+CD123+CD45RA-CD10-, MEP - Lin-CD34+CD38+CD123-CD45RA-CD10-.

Gene expression down-regulation in prostate tumor-associated stromal cells involves organ-specific genes

Project description:The prostate stroma is a key mediator of epithelial differentiation and development, and potentially plays a role in the initiation and progression of prostate cancer. Isolation and characterization of viable populations of the constituent cell types of prostate tumors could provide valuable insight into the biology of cancer. The CD90+ stromal fibromuscular cells from tumor specimens were isolated by cell-sorting and analyzed by DNA microarray. Dataset analysis was used to compare gene expression between normal and tumor-associated reactive stromal cells. Reactive stroma is characterized by smooth muscle differentiation, prostate down-regulation of SPOCK3, MSMB, CXCL13, and PAGE4, bladder down-regulation of TRPA1, HSD17B2, IL24, and SALL1, and an up-regulation of CXC-chemokines. This study identified a group of differentially expressed genes in CD90+ reactive stromal cells that are potentially involved in organ development and smooth muscle cell differentiation.

Reprogramming of prostate cancer-associated stromal cells

Project description:CD90+ prostate cancer-associated (CP) stromal cells represent a disease cell type found only in tumor tissue. Genetic reprogramming by induced pluripotent stem (iPS) cell technology might be used to “normal gene expression of diseased cells thereby providing a cure. The resultant iPS cells would no longer express the disease program, and, like stem cells, might respond to normal differentiative signaling. Thus, CP stromal cells, isolated from tumor tissue and cultured in vitro, were transfected with POU5F1/LIN28/NANOG/SOX2 lentiviral vectors. iPS cells were obtained at a frequency of 10^4. Transcriptome analysis showed an almost complete match in gene expression between the iPS cells and human embryonic stem cells. Genes of CP stromal cells were fully inactivated. CP stromal cells were isolated from tissue, cultured and transfected with lentiviral vectors containing NANOG, SOX2, POU5F1, LIN28. The resultant induced pluripotent cells were analyzed by DNA microarrays.
