Single-cell transcriptomics reveals natural product Shi-Bi-Man promotes hair regeneration

ABSTRACT: Purpose: This study aimed to explore the mechanism of SBM to promote hair regeneration through single-cell transcriptomics Methods: Supplementation with intragastric administration or smear administration of SBM in artificially shaved C57BL/6 mice to observe its hair growth. Single-cell RNA sequencing were performed to explore the role of SBM for hair regeneration. Results: SBM significantly induced hair growth compared with control treatment.The results of single-cell sequencing revealed that after SBM treatment, the number of hair follicle stem cells (HFSCs) and dermal papilla cells (DPCs) increased significantly. Cell interactions and volcano maps show that interaction of FGF signaling pathway was significantly enhanced, in which FGF7 expression was especially upregulated in DPCs. In addition, Wnt signaling pathway also had a partially enhanced effect on the interactions between various cells in the skin. Network pharmacology study showed that the promotion of FGF and Wnt pathways by SBM was also enriched in alopecia diseases. Conclusion: We report that SBM has a potential effect on the promotion of hair growth by mainly activating FGF signaling pathway. The use of SBM may be a novel therapeutic option for hair loss.

Introduction of the TERT and BMI1 Genes into Murine Dermal Papilla Cells Ameliorates Hair Inductive Activity

Project description:Dermal papilla cells (DPCs) are located at the bottom of hair follicles and play important roles on hair induction by interacting with epidermal cells. DPCs are promising cell sources for hair regeneration therapy for alopecia patients. However, freshly isolated DPCs rapidly lose their hair inductive activity and proliferative potential under culture conditions. We examined the effects of telomere reverse transcriptase (TERT) and B-cell-specific Moloney murine leukemia virus insertion region 1 (BMI1) on extending the life span of murine DPCs as well as on hair inductive activity.TERT and BMI1 genes were introduced into murine DPCs using lentivirus vectors. Hair inductive activity of transfected DPCs (t-DPCs) was determined by in vivo chamber assay in nude mice. Transcripts between intact dermal papillae (DPs) and cultured DPCs were compared by microarray analysis.

Human dermal papilla cell culture medium iTRAQ

Project description:Alopecia is an exceedingly prevalent problem and lacks effective therapy. Recently, research has focused on early-passage dermal papilla cells (DPCs), which have hair inducing activity both in vivo and in vitro. Our previous study indicated that factors secreted from early-passage DPCs contribute to hair follicle (HF) regeneration. To identify which factors are responsible for HF regeneration and why late-passage DPCs lose this potential，we collected 48-h-culture medium (CM) from both of passage 3 and 9 DPCs and subcutaneously injected the DPC-CM into NU/NU mice. Passage 3 DPC-CM induced HF regeneration, based on the emergence of a white hair coat, but passage 9 DPC-CM not. In order to identify the key factors responsible for hair inductive capacity, CM from passage 3 and 9 DPCs was analyzed by iTRAQ-based quantitative proteomic technology. We identified 1360 proteins, of which 213 proteins were differentially expressed between CM from early-passage vs. late-passage DPCs, including SDF1, MMP3, biglycan and LTBP1.Further analysis indicated that the differentially-expressed proteins regulated the Wnt, TGF-β and BMP signaling pathways, which directly and indirectly participate in HF morphogenesis and regeneration. Subsequently, we selected 19 proteins for further verification by multiple reaction monitoring (MRM) between the two types of CM. These results would be used to identify the key factors for inducing HF regeneration and reveal the molecular mechanisms of losing inductive ability of DPCs. Furthermore, it is possible to explore some drugs for alopecia in the clinic according to this secretome date analysis.

Transcription profiles of human dermal sheath cells cultured under 20%-O2 or 6%-O2 condition

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.

Transcriptome Analysis of Dihydrotestosterone-treated 2D- and 3D-cultured Dermal Papilla Cells

Project description:Hair follicle growth inhibitory effect of dihydrotestosterone (DHT)-treated two-dimensional (2D)- and 3D-cultured DPCs were evaluated. 2D- and 3D-cultured DPC proliferation was inhibited after co-culturing with outer root sheath (ORS) cells under DHT treatment. Moreover, gene expression levels of β‐catenin and neural cell adhesion molecule (NCAM) were significantly decreased and those of cleaved caspase-3 significantly increased in 2D- and 3D-cultured DPCs with increasing DHT concentrations. ORS cell proliferation also significantly increased after co-culturing in the control-3D model compared with the control-2D model. ki67 downregulation and cleaved caspase-3 upregulation in DHT-2D and 3D groups significantly inhibited ORS cell proliferation. Sequencing showed an increase in the expression of genes related to extracellular matrix synthesis in the 3D model group. Additionally, the top 10 hub genes were identified, and the expression of nine chemokine-related genes in DHT-treated DPCs was found significantly increased. We also identified the interactions between transcription factor (TF)–genes and microRNAs with hub genes and the TF–microRNA coregulatory network. Overall, the findings indicate that 3D-cultured DPCs are more representative of in vivo conditions than are 2D-cultured DPCs, and contribute to our understanding of the molecular mechanisms underlying androgen-induced alopecia.
