Transcription profiling of human epithelial stem cells co-cultured with the dermal papilla

ABSTRACT: Clonogenic keratinocyte stem cells isolated from the bulge area of human telogen follicles were co-cultured with dermal papilla cells in a transwell system. RNA was isolated from stem cells for different periods of time (day 0, 1, 2, and 5) after co-culture with DP and analyzed for changes in gene expression using Genechip microarrays.

Dermal papilla-induced hair differentiation of adult epithelial stem cells from human skin.

Roh Cecilia C Tao Qingfeng Q Lyle Stephen S

Physiological genomics 20040803 2

The epithelial-mesenchymal interactions between keratinocyte stem cells and dermal papilla (DP) cells are crucial for normal development of the hair follicle as well as during hair cycling. During the cyclical regrowth of a new lower follicle, the multipotent hair follicle stem cells are stimulated to proliferate and differentiate through interactions with the underlying mesenchymal DP cells. To characterize the events occurring during the process of epithelial stem cell fate determination, we u ...[more]

Gene expression in feather dermal papilla (DP)

Project description:The feather follicle is a “professional” regenerative organ that undergoes natural cycling and, regeneration after wound plucking. Similar to mammalian hair follicle, dermal papilla (DP) controls feather regeneration, shape, size, and axis. Here we report gene expression profiling for feather DP at different growth stages. For growth phase, we compared gene expression of DP, the ramogenic zone of feather branching epithelium (Erz) and the mesenchymal pulp (Pp). We also compared gene expression of DP at resting phase. To characterize the feather regeneration process, we further profiled gene expression at Day-2 and Day-4 post wound. Our results provide a resource for investigating feather growth and regeneration. Examination of gene expression in dermal papilla (DP) at growth phase and resting phase feather follicle, and during feather regeneration.

Dermal papilla signature gene expression in immortalized human dermal papilla cells from balding and non-balding scalp

High-throughput sequencing of extracellular vesicles from human dermal papilla cells

Project description:The use of dermal papilla cells for hair follicle (HF) regeneration is long accepted much attention. However, cultured dermal papilla cells tend to lose the hair-inducible capability during passaging, which restricts its application. Increasing evidences indicate that dermal papilla cells exert their regulatory function of HF growth mainly through their unique paracrine properties, opening up a way to exosome therapies.This study aimed to explore the effects of exosomes from high and low-passaged human scalp follicle dermal papilla cells (DP-Exos) on hair follicle stem cells (HFSCs) activation and hair growth, and to investigate the underline mechanism. DP-Exos were isolated by ultracentrifugation and cultured with human scalp follicles and HFSCs. The hair elongation and cell proliferation was assessed. Quantitative real-time PCR (qRT-PCR) and Western-blot were performed to detect the expression levels of a class of miRNAs and proteins which have positive roles in regulating hair growth and HFSCs proliferation. High throughput miRNA sequencing of miRNAs in high (P8) and low-passaged (P3) DP-Exos was performed, and the utmost miRNA and its target gene was identified via bioinformatics analysis.

Transcriptome analysis of cells in mouse hairy melanocytic nevi

Project description:RNA-seq data was obtained from different skin cell types at two time points: postnatal day P30, when WT dorsal hair follicles are in actively growing state (aka anagen) and P56, when WT hair follicles are in resting state (aka telogen). Cell types include: Bulge stem cells (B), dermal papilla fibroblasts (DP), secondary hair germ cells (HG), melanocytes (Melan), myeloid cells (Myel) and CD45-positive immune cells (I). All cell were FACS sorted and only live single cells were collected for RNA extraction.

Transcriptome comparison of balding and non-balding dermal papilla aggregates from NHEK co-culturing

Project description:Androgenetic alopecia (AGA, male patterned baldness) is a prevalent hair loss condition in males that develops due to the influence of androgens and genetic predisposition. The keratinocytes-surrounded spheroid dermal papilla (DP) at the base of the hair follicle is essential in hair morphogenesis and cycling. With the aim of elucidating genes involved in AGA pathogenesis, we co-cultured immortalised balding and non-balding human DP cells (DPC) derived from male AGA patients with epidermal keratinocyte (NHEK) using multi-interfacial polyelectrolyte complexation (MIPC) technique, and compared gene expression using RNA-seq between isolated balding and non-balding DP aggregates.

Transcription profiling of mouse hair follicles in the 2nd telogen to anagen transition

Project description:Hair Follicle regeneration relies on both epithelial components (bulge and hair germ cells) and a mesenchymal one (dermal papilla cells). We used microarrays to detail the global programme of gene expression underlying organ regeneration at the transition between quiescent stages (early and middle telogen) and the initiation of a new growth (late telogen). Experiment Overall Design: These microarray at the 3 different stages were designed to identify signals released by the mesenchymal dermal papilla cells to activate epithelial growth, their target genes in the hair germ and bulge compartments, and to get at gene signature differences and similarities between hair germ and bulge cells.

Expression data of freshly microdissected human hair follicle dermal papilla and its comparisons

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.

Gene expression data of human dermal pilla cells, human induced pluripotent stem cell-derived CD271+CD90+ mesenchymal stem cells before and after the induction toward dermal papilla cells

Project description:To assess if human induced pluripotent stem cell-derived mesenchymal stem cells (hiPSC-MSCs) could be induce to acquire dermal papilla (DP) properties (especially hair inductive capacity), hiPSCs were initially programmed in serum-free MSC medium with FGF, TGFbeta and PDGF. Subsequently, hiMSCs were exposed to retinoic acid and activators of WNT, BMP and FGF signaling pathways. Global gene expression profiles were compared among primarily cultured human DP cells, hiPSC-MSCs before and after induction.
