Project description:In our study, we found that low-passage dermal papilla cells (DPCs) and dermal sheath cells (DSCs) has higher homing rate than that of high-passage DPCs and DSCs. To uncover the molecular mechanisms underlying the difference of homing rate between low-passage DPCs/DSCs and high-passage DPCs/DSCs, we perform transcriptome analysis of mRNA expression profiles of low-passage and high-passage DPCs and DSCs.

Project description:We investigated the effect of low oxygen culture on the proliferation and hair inductive capacity of human dermal papilla cells (DPCs) and dermal sheath cells (DSCs). DPCs and DSCs were cultured in atmospheric/hyperoxia (20% O2), physiological/normoxia (6% O2), or hypoxia (1% O2) conditions, respectively. Proliferation of DPCs and DSCs was highest under normoxia. Hypoxia inhibited proliferation of DPCs but enhanced proliferation of DSCs. In DPCs, hypoxia down-regulated expression of hair inductive capacity-related genes, including BMP4, LEF1, SOX2, and VCAN, and normoxia up-regulated expression of ALP. In DSCs, both normoxia and hypoxia up-regulated SOX2 expression, and hypoxia down-regulated BMP4 expression. Microarray analysis revealed increased expression of pluripotency-related genes, including SPRY, NR0B1, MSX2, IFITM1, and DAZL, under hypoxia. In an in vivo hair follicle reconstitution assay, cultured DPCs and DSCs were transplanted with newborn mouse epidermal keratinocytes into nude mice using a chamber method. In DPCs, normoxia allowed the most efficient induction of hair follicles. In DSCs, hypoxia allowed the most efficient induction and maturation of hair follicles. These results suggest that low oxygen culture enhances the proliferation and maintains functions of human DPCs and DSCs and could be used for skin engineering and clinical applications.

Project description:Hair follicles undergo recurrent cycling of controlled growth (anagen), regression (catagen), and relative quiescence (telogen) with a defined periodicity. Taking a genomics approach to study gene expression during synchronized mouse hair follicle cycling, we discovered that, in addition to circadian fluctuation, CLOCK-regulated genes are also modulated in phase with the hair growth cycle. During telogen and early anagen, circadian clock genes are prominently expressed in the secondary hair germ, which contains precursor cells for the growing follicle. Analysis of Clock and Bmal1 mutant mice reveals a delay in anagen progression, and the secondary hair germ cells show decreased levels of phosphorylated Rb and lack mitotic cells, suggesting that circadian clock genes regulate anagen progression via their effect on the cell cycle. Consistent with a block at the G1 phase of the cell cycle, we show a significant upregulation of p21 in Bmal1 mutant skin. While circadian clock mechanisms have been implicated in a variety of diurnal biological processes, our findings indicate that circadian clock genes may be utilized to modulate the progression of non-diurnal cyclic processes. To investigate the molecular control of hair follicle cycling, we profiled mRNA expression in mouse dorsal skin at multiple representative time points in the synchronized second postnatal hair growth cycle and in a depilation-induced hair growth cycle. For profiling of second synchronized and depilation-induced hair growth cycle, the same upper-mid region of dorsal skin was excised from C57BL/6 mice at representative postnatal days (P). The time points for second hair growth cycle are classified into different phases of the hair growth cycle based on established morphological guidelines as follow: early anagen (P23, P25), mid anagen (P27), late anagen (P29, P34), early catagen (P37, P39), mid catagen (P41), and telogen (P44). Depilation-induced hair growth cycle by applying wax/rosin mixture on the dorsal skin of seven-week old mice (all follicles in telogen) was performed on mice. The corresponding phases of the hair growth cycle at number of days following depilation (D) is as follow: early anagen (D3), mid anagen (D5), late anagen (D8, D12), and early catagen (D17). For each time point, multiple biological replicates were profiled, with each mouse dorsal skin separately hybridized to an Affymetrix array.

Project description:Purpose: The goals of this study were to identify Pathways that Tregs utilize in the skin to maintain tissue homesostasis in the context of hair follcile cycling. Methods: Hair follicle stem cells (HFSCs), in the presence and absence of Tregs, were induced into cycle through a model of depilation induced anagen. HFSCs were then purified by cell sorting at day 4 post depilation based on cell surface marker expression (CD45 negative, MHC Class II negative, Sca-1 negative, EpCAM negative, CD34 Positive, Integrin alpha6 High) to generate mRNA transcription profiles. Results: Transcriptional profiling revealed a significant reduction in proliferation/differentiation associated genes expressed in HFSCs isolated from Treg depleted mice Conclusion: Our study represents the first detailed analysis of Treg modulation of tissue stem cell behaviour mRNA profiles of HFSC isolated from 7-10 week old WT and Foxp3-DTR mice at 4 days post depilation of dorsal skin.

Project description:The aim of this study was to determine the effects of Alpinetin (AP) on transcriptome profiles of hair follicle regeneration. Depilation was performed on mice back skin. After 24 hours, the depilated area was treated with 3 mg/ml Alpinetin that were dissolved in 65% ethanol once a day. At day 4 post depilation, skin samples without interfollicular epidermis were obtained for RNAseq. We identified 1567 different expression genes between AP and VC group by using an optimized data analysis workflow.
