ABSTRACT: The libraries contained in this experiment come from hair follicle dermal papilla primary whole cells, HFDPC isolated from independent donors. They are stranded PE101 Illumina Hi-Seq RNA-Seq libraries from rRNA-depleted Total RNA > 200 nucleotides in size.

Project description:Dermal papilla cells isolated from the human hair follicle are capable of inducing hair growth in recipient epithelia. However, demonstrating disparity from rodent dermal papilla, human cells lose this inductive competance immediately upon growth in culture under normal growth conditions. We grew dermal papilla cells in hanging drop cultures that are morphologically akin to intact dermal papilla, and found that by enhancing the environment for aggregation, we could restore the inductive capacity of human dermal papilla cells in culture. The underlying genes that regulate the inductive potential of dermal papilla cells is not well understood, and we sought to use global profiling to identify key genes and pathways related to inductive competance within dermal papilla cells. We used Affymetrix microarrays to profile human dermal papilla cells in both hair inducing, and non-hair inducing states. Affymetrix microarrays were used to to perform profiling of human dermal papilla cells, both as intact tissues (freshly isolated from scalp), and at several stages in subsequent two dimensional culture; cell explant outgrowths (p0), cells at passage 1 (p1), passage 3 (p3) and passage 5 (p5). RNA was isolated from cultured cells 72 hours after feeding. Cells at passage 3 were also grown in hanging drops to form dermal spheroids, that were used for RNA collection 48 hours after establishment. All experiments were performed using tissue from three biological replicates (#D5, D6, D7),

Project description:Here we have developed a novel FACS strategy to prospectively isolate hair follicle dermal stem cells, dermal sheath and dermal papilla cells from adult skin initiating synchronous hair follicle regeneration and identified Hic1 as a marker of hfDSCs and Rspondins as stimulators of hfDSCs and epithelial cells, and subsequently hair follicle regeneration
Project description:During the epidemic of the dengue virus (DENV) infection in Taiwan in 2014 and 2015, we observed an abnormally high frequency of increased scalp hair shedding in infected individuals that could not be explained by telogen effluvium. In this study, the mechanism of hair loss caused by DENV was explored. Human hair follicle dermal papilla cells (HFDPCs) are essential for hair follicle morphogenesis and cycling. Thus, we established an in vitro DENV infection model in HFDPCs. On immunofluorescence analysis, HFDPCs that were susceptible to DENV infection responded to type I interferon (IFN) treatment, and the cells showed antibody-dependent enhancement (ADE) effect. The expression of the pro-inflammatory cytokines, interleukin 6 (IL-6), and tumor necrosis factor-alpha (TNF-?), revealed an inflammatory response in DENV-infected HFDPCs. In particular, DENV infection impaired cell viability, and it activated caspase-associated cell death signaling in HFDPCs. In conclusion, our data indicate that direct infection with DENV causes inflammation and cell death in HFDPCs, which is involved in the mechanisms of hair loss after DENV infection. The knowledge of DENV infection in an immune-privileged tissue, such as hair follicles, may suggest their use for further studies on post-dengue fatigue syndrome (PDFS).
Project description:The dermal papilla (DP) of the hair follicle plays crucial roles in the hair follcie morphogenesis and cycling. Thus, the elucication of human DP molecular signature is of great interest. DP cell culture by conventional method impairs intrinsic properties of DP cells. Isolatoion of human DP is hampered by the lack of specific cell surface markers. Thus, it still depends on manual microdissection, with which the removal of minor contamination is unfeasible. Cultured DP cells are mostly pure. Aggregation of cultured DP cells was shown to restore some intrinsic properties in cultured DP cells. Fibroblasts are distinct dermal cell population and provide baseline for DP arrays.

Cultured DP cells are mostly pure. Aggregation of cultured DP cells was shown to restore some intrinsic properties in cultured DP cells. Fibroblasts are distinct dermal cell population and provide baseline for DP arrays. Four sets of Genechip microarrays were generated from freshly-microdissected DPs (fDP), cultured DP cells (cDP), cultured fibroblasts (Fibro) collected from respective volunteers. Two sets of Genechips were additionally prepared from aggregated DP cells (agDP) and cultured DP cells which were used for the generation of agDPs (each set derived from respective volunteer). These Genechips can be compared to elucidate the genes possibly contribute to intrinsic property of intact human DPs. For instance, comparisons between cultured DP (cDP) and fibroblast (Fibro) or between aggregated DP (agDP) and cDP could sort out potential DP signature genes, as each population is predominantly consisted of DP cells. When the expression levels of those genes were compared between fDP and cDP chips, the genes up- or equally expressed in fDPs should represent DP signature genes.
