Transcription profiling of human hair follicles from men and women

ABSTRACT: Investigation of Gene Expression Profiling in Unstaged Head Hair Follicles Plucked from Men and Women Experiment Overall Design: Total RNA was extracted from 1-3 unstaged follicles plucked from the scalp of each of 36 adult human volunteers. The average quantifiable yield of RNA per follicle was 112.5 ng. Ten samples were selected, based on ribosomal ratio, relative integrity number and total yield, for expression profiling. By preamplifying the extracted RNA (starting with as little as 30 ng), sufficient labeled RNA was generated to conduct Afymetrix-based gene expression analysis.

Characterizing gene expression in hair follicles can help to elucidate the hair growth cycle by delineating the genes and pathways involved in follicular growth and degeneration. The objectives of this study were to determine whether intact RNA could be extracted from a small number of plucked, unstaged hair follicles in sufficient quantity to conduct gene expression profiling, and to conduct global gene expression profiling. To this end, RNA was extracted from 1 to 3 unstaged follicles plucked ...[more]

Plucked hair follicles from patients with chronic discoid lupus erythematosus show a disease-specific molecular signature

Project description:When faced with clinical symptoms of scarring alopecia – the standard diagnostic pathway involves a scalp biopsy which is an invasive and expensive procedure. Furthermore, clinical activity of scarring alopecias is often difficult to assess as symptoms of permanent damage and signs of activity can overlap or be difficult to distinguish. Here we report that gene expression analysis of only a small number of hair follicles (HF) plucked from lesional areas of the scalp is sufficient to characterise chronic discoid lupus erythematosus (CDLE). Lesional and non-lesional HFs were extracted from the scalp of patients with CDLE, psoriasis and healthy controls. The expression profile from CDLE HFs coincides with published profiles of CDLE from skin biopsy and was consistent with histopathological diagnostic features of CDLE. We therefore propose that information obtained from this non-invasive approach are sufficient to diagnose scalp LE.

Mouse bulge (CD34+CD200+CD49+) versus secondary hair germ (CD34-CD200+CD49+) versus interfollicular epidermis (CD34-CD200-CD49+)

Project description:Mouse back skin was disassociated to single cells, sorted by cell surface markers and tested by microarrray To compare the gene expression of mouse bulge (CD34+CD200+CD49+) versus secondary hair germ (CD34-CD200+CD49+) versus interfollicular epidermis (CD34-CD200-CD49+) xx Bald scalp retains hair follicle stem cells but lacks CD200-rich and CD34-positive hair follicle progenitor cells Androgenetic 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. 4 independent biologic replicates (each pooled from 3 distinct mice) were sorted for Mouse bulge (CD34+CD200+CD49+) versus secondary hair germ (CD34-CD200+CD49+) versus interfollicular epidermis (CD34-CD200-CD49+)

Expression data from the dermis of human stretched scars and patient-matched healthy dermis from occipital scalps

Project description:It is well accepted that elevated mechanical tension of the skin surrounding a healing wound stimulates a fibrotic cascade of events and contributes to an increased size of scars. A laxity paradox in the field of hair transplantation describes a phenomenon opposing this view. During Strip Follicular Unit Transplantation (Strip FUT), surgeons remove a strip of scalp skin (approximately 5 cm x 10 cm, depending on the number of hair follicles required) from the occipital scalp, which is then used to harvest hair follicles that will be transplanted into the balding frontal scalp. Most patients with normal scalp skin laxity heal with narrow normotrophic scars, while a small number of patients (14%) with very loose scalp skin, and so low residual skin tension, heal with post operating scar widening (4 - 12 mm). These scars, referred to as stretched scars in the hair transplantation field, often require revision surgery or secondary hair grafting into the scar. We hypothesise that stretched scars present a unique transcriptional signature different from other types of scars. To determine the gene expression profile of stretched scars, we used Affymetrix microarrays to perform profiling of fibrotic dermis and the surrounding patient-matched healthy dermis.

Metabolomics Analysis of Frontal Fibrosing Alopecia

Project description:Scarring alopecia consists of a collection of disorders characterized by destruction of hair follicles, replacement with fibrous scar tissue, and irreversible hair loss. Alopecia affects men and women worldwide and can be a significant source of psychological stress and depression for affected individuals. The purpose of this study was to explore metabolic profiles in scalp tissue samples from normal control subjects (n=6) and in matched samples obtained from affected (n=12) and unaffected (n=12) areas of the scalp in patients with lymphocytic Frontal Fibrosing Alopecia (FFA). Frontal fibrosing alopecia results from destruction of hair follicles by an inflammatory lymphocytic infiltrate that is localized around the upper portion of the hair follicle.

Isolated of dermal papilla cells from follicular unit extraction

Project description:Hair follicles were originally obtained in the form of intact hair follicles from human scalp during microscopic hair transplant procedures of Follicular Unit Extraction (FUE). Dermal papilla cells were freshly isolated or traditionally isolated and cultured in basic medium supplied with 10% FBS. Freshly-isolated DPCs and cultured DPCs were sequenced using third generations of sequencing.
