(Submitter supplied) 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.

(Submitter supplied) Hair follicle matrix, outer root sheath, dermal papilla cells and melanocytes and a dermal fraction enriched in fibroblasts were FACS isolated from 4d backskins. Targets from two biological replicates of each were generated and the expression profiles were determined using Affymetrix Mouse Genechip 430A arrays. Comparisons between the sample groups allow the identification of cell-type specific genes. more...

(Submitter supplied) Expression of deltaNB-cateninER allows the time and duration of B-catenin activation to be controlled precisely through the application of 4OHT. We have shown that B-catenin activation in adult mouse epidermis stimulates de novo hair follicles and the formation of a new bulge and melanocyte niche. We utilize Affymetrix Mouse Genome 430A 2.0 oligonucleotide arrays to investigate the differential regulation of RNA in skin from 7 week old female deltaNB-cateninER transgenic mice following 0, 1, or 7 days B-catenin activation in the epidermis. more...

(Submitter supplied) We developed a Tet-inducible system to express deltaNp63alpha isoform under the control of keratin 5 promoter. Transgenic mice, which were Bigenic (BG) developed a severe skin phenotype with abnormal keratinocyte differentiation and defects in hair follicle development and cycling. Skin samples from transgenic animals and wild type animals were analyzed for global transcriptome changes.

(Submitter supplied) 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. more...

(Submitter supplied) 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.

(Submitter supplied) The hair follicle (HF) is a complex miniorgan that serves as an ideal model system to study stem cell (SC) interactions with the niche during growth and regeneration. Dermal papilla (DP) cells are required for activating SCs during the adult hair cycle, but the signal exchange between niche and SC precursors/transit amplifying progenitor cells (TACs) that regulates HF morphogenetic growth is largely unknown. more...

(Submitter supplied) Different types of hair follicles can be found in the skin of mice. It is believed that the signals that control hair follicle differentiation arise from cells in a structure called the dermal papilla. Understanding the nature of those signals is of interest for the biology of the normal tissue. We have developed a technique for isolation of dermal cells by enzymatic digestion of intact skin. We have identified two subpopulations of cells that can be separated by FACS. more...

(Submitter supplied) TERT is an essential protein component of telomerase, a ribonuclearprotein complex that protects chromosomal ends. Ectopic expression of TERT in mouse skin activates hair follicle stem cells and induces active growth phase of hair cycles, called anagen. This activity of TERT is independent of its reverse transcriptase function, indicating that this is a non-telomeric function of TERT. We performed time-course microarray analysis using conditional bi-transgenic mice (iK5-TERT) to understand the mechanism of this novel non-telomeric function of TERT. more...
