Norrin, frizzled-4, and Lrp5 signaling in endothelial cells controls a genetic program for retinal vascularization.

View SamplesTranscriptional profiles of Fz4-/- retinal endothelial cells were compared to that of wild type endothelial cells under various culture conditions. The goal was to identify the transcriptional response to Frizzled 4 signaling in cultured retinal endothelial cells. To analyze the Norrin response of WT and Fz4-/- retinal endothelial cells in culture, we co-cultured these cells either with HEK293 cell line that stably expresses Norrin or with control 293 cells.

View SamplesAndrogenetic alopecia (AGA) or common baldness results from a marked decrease in hair follicle size. This miniaturization may be related to loss of hair follicle stem or progenitor cells. To test this hypothesis, we analyzed bald and non-bald scalp from the same individuals for the presence of hair follicle stem and progenitor cells using flow cytometry to quantitate cells expressing CYTOKERATIN 15 (KRT15), CD200, CD34 and ALPHA-6-INTEGRIN (ITGA6). High levels of KRT15 expression correlated with stem cell properties of small cell size and quiescence. Cells with the highest level of KRT15 expression were maintained in bald scalp; however, distinct populations of CD200high ITGA6high cells and CD34-positive cells were markedly diminished. Consistent with a progenitor cell phenotype, the diminished populations localized closely to the stem-cell rich bulge area but were larger and more proliferative than the bulge stem cells. In functional assays, analogous CD200 high /Itga6 high cells from murine hair follicles were multipotent and generated new hair follicles in skin reconstitution assays. These findings suggest that a defect in stem cell activation plays a role in the pathogenesis of AGA.
Bald scalp in men with androgenetic alopecia retains hair follicle stem cells but lacks CD200-rich and CD34-positive hair follicle progenitor cells.

View SamplesTo characterize the long-term effect on the transcriptome of a decrement in Norrin/Fz4/Lrp signaling, microarray hybridization was performed with RNA from acutely dissociated and anti-PECAM immunoaffinity-purified adult WT, Fz4-/-, Lrp5-/-, and Norrin- retinal vascular cells.
