Dermal papilla is considered the control center of hair follicle growth and hair cycle. The secondary hair follicle (producing cashmere) growth cycle of the Cashmere goat ( Capra hircus) is circannual, and each growth phase can be easily distinguished by its long duration. To identify gene expression patterns and differences of the dermal papilla cell (DPC) between the anagen and telogen phases, we established two DPC lines: ana-DPCs (DPCs derived from the anagen secondary hair follicle) and tel-DPCs (DPCs derived from the telogen secondary hair follicle). Compared with the ana-DPCs, the tel-DPCs lost the capacity to form cell aggregates and showed lower cell proliferation rate. Transcriptome sequencing revealed that 825 genes were differentially expressed by at least threefold between the two DPC lines. These genes were significantly enriched in cell cycle control, cell division, and chromosome partitioning from the Eukaryotic Orthologous Groups of proteins (KOG) database and in cell cycle, cell adhesion molecules, cytokine-cytokine receptor interaction, and p53 signaling pathway from the Kyoto Encyclopedia of Gene and Genomes (KEGG) database. Enrichment analyses revealed that in the middle of the telogen the DPCs of secondary hair follicles (SHFs) seemed on the one hand to promote the degeneration of SHFs and cessation of cashmere growth, while on the other hand to resist self-apoptosis and prepare for the regeneration or revivification of fully functional dermal papillae. These findings provide a better understanding of hair follicle growth and will be useful for identification of novel molecules associated with the control of hair growth cycle.

Cashmere, which has high economic value, is made from the secondary hair follicles of cashmere goat skin. Dermal papilla cells (DPCs) are considered the center for regulation of hair growth, which is closely related to hair follicle growth. We constructed LEF-1 overexpression and interference experimental groups of goat DPCs to investigate LEF-1 regulation of DPCs proliferation by Wnt signaling, and provide a theoretical basis for improving cashmere yield. In primary DPCs, LEF-1, β-catenin, C-myc, and cyclin D1 expression in the LEF-1 overexpression group was 9.25-, 1.27-, 1.74-, and 1.63-fold, respectively, that of the control. LEF-1, β-catenin, C-myc, and cyclin D1 expression in the LEF-1 interference group was 0.20-, 0.75-, 0.38-, and 0.39-fold, respectively, that of the control. In secondary DPCs, LEF-1, β-catenin, C-myc, and cyclin D1 expression in the LEF-1 overexpression group was 10.53-, 1.48-, 1.64-, and 1.39-fold, respectively, that of the control. LEF-1, β-catenin, C-myc, and cyclin D1 expression in the LEF-1 interference group was 0.21-, 0.71-, 0.40-, and 0.36-fold, respectively, that of the control. Primary and secondary DPCs proliferation rates changed with LEF-1 expression. Therefore, the LEF-1 regulation pattern of cell proliferation through Wnt signaling is similar in both DPCs.

This study is an investigation to evaluate how the controlled release of different growth factors affects the hair follicle growth of mice in the second anagen stage of hair cycle. For the controlled release of basic fibroblast growth factor (bFGF) and hepatocyte growth factor (HGF), they were incorporating into biodegradable gelatin hydrogels, while a biodegradable collagen hydrogel was used for incorporation of vascular endothelial growth factor (VEGF). After subcutaneous implantation of the different hydrogels incorporating each growth factor or injection of phosphate buffered saline (PBS) containing the same dose of growth factor into the back of mice, the hair follicle growth was evaluated photometrically and histologically based on four parameters: the skin color of reverse side of the implanted or injected site, the number of vessels newly formed, the area occupied by hair follicle tissue, and the hair length. The area in close proximity to the implanted site of hydrogels incorporating growth factor was still dark in color 10 days after application. The hydrogel incorporating any type of growth factor enabled the hair follicles to increase the size, leading significantly enhanced area occupied by hair follicles per unit area of tissue. Implantation of the hydrogels incorporating growth factor increased significantly the number of blood vessels newly formed. Moreover, the length of hair shaft was elongated by the hydrogel incorporating growth factor to a significantly higher extent than the corresponding growth factor. Neither empty gelatin nor collagen hydrogels affected the hair follicle growth. These results indicate that the hydrogel incorporating growth factor induced the anagen-preservable activity. We conclude that the controlled release enabled growth factors to positively act on the hair growth cycle of mice, irrespective of the factor type.

Hair Follicle Growth

The dermal papilla comprises mesenchymal cells in hair follicles, which play the main role in regulating hair growth. Maintaining the potential hair inductivity of dermal papilla cells (DPCs) and dermal sheath cells during cell culture is the main factor in in vitro morphogenesis and regeneration of hair follicles. Using common methods for the cultivation of human dermal papilla reduces the maintenance requirements of the inductive capacity of the dermal papilla and the expression of specific dermal papilla biomarkers. Optimizing culture conditions is therefore crucial for DPCs. Moreover, exosomes appear to play a key role in regulating the hair follicle growth through a paracrine mechanism and provide a functional method for treating hair loss. The present review investigated the biology of DPCs, the molecular and cell signaling mechanisms contributing to hair follicle growth in humans, the properties of the dermal papilla, and the effective techniques in maintaining hair inductivity in DPC cultures in humans as well as hair follicle bioengineering.

Abstract Background: Cashmere goats make an outstanding contribution to the livestock textile industry and their cashmere is famous for its slenderness and softness and has been extensively studied. However, there are few reports on the molecular regulatory mechanisms of the secondary hair follicle growth cycle in cashmere goats. In order to explore the regular transition through the follicle cycle and the role of key genes in this cycle, we used a transcriptome sequencing technique to sequence the skin of Inner Mongolian cashmere goats during different months. We analyzed the variation and difference in genes throughout the whole hair follicle cycle. We then verified the regulatory mechanism of the cashmere goat secondary hair follicle growth cycle using fluorescence quantitative PCR. Results: The growth cycle of cashmere hair could be divided into three distinct periods: a growth period (March–September), a regression period (September–December), and a resting period (December–March). The results of differential gene analyses showed that March was the most significant month. Cluster analysis of gene expression throughout the whole growth cycle further supported the key nodes of the three periods of cashmere growth, and the differential gene expression of keratin corresponding to the ground haircashmere growth cycle further supported the results from tissue slices. Quantitative fluorescence analysis showed that KAP3-1, KRTAP 8-1, and KRTAP 24-1 genes had close positive correlation with the cashmere growth cycle, and their regulation was consistent with the growth cycle of cashmere. Conclusion: The growth cycle of cashmere cashmere could be divided into three distinct periods: a growth period (March–September), a regression period (September–December) and a resting period (December–March). March was considered to be the beginning of the cycle. KAP and KRTAP showed close positive correlation with the growth cycle of secondary hair follicle cashmere growth, and their regulation was consistent with the cashmere growth cycle. But hair follicle development-related genes are expressed earlier than cashmere growth, indicating that cycle regulation could alter the temporal growth of cashmere. This study laid a theoretical foundation for the study of the cashmere development cycle and provided evidence for key genes during transition through the cashmere cycle. Our study provides a theoretical basis for cashmere goat breeding.

Abstract. Inner Mongolian Cashmere goat is an excellent local breed selected for the dual-purpose of cashmere and meat. There are three lines of Inner Mongolian Cashmere goat: Erlangshan, Alashan and Aerbasi. Cashmere is a kind of precious textile raw material with a high price. Cashmere is derived from secondary hair follicle (SHF), while hair is derived from primary hair follicle (PHF). The growth cycle of SHF of cashmere goat is 1 year, and it can be divided into three different stages: anagen, catagen and telogen. In this study, we tried to find some important influence factors of SHF growth cycle in skin tissue from Inner Mongolian Cashmere goats by RNA sequencing (RNA-Seq). Three female Aerbasi Inner Mongolian Cashmere goats (2 years old) were used as experimental samples in this study. Skin samples were collected in September (anagen), December (catagen) and March (telogen) at dorsal side from cashmere goats. Results showed that over 511 396 044 raw reads and 487 729 890 clean reads were obtained from sequence data. In total, 51 different expression genes (DEGs) including 29 downregulated genes and 22 upregulated genes were enriched in anagen–catagen comparing group. The 443 DEGs contained 117 downregulated genes and 326 upregulated genes that were enriched in catagen–telogen comparing group. In telogen–anagen comparing group, 779 DEGs were enriched including 582 downregulated genes and 197 upregulated genes. The result of gene ontology (GO) annotation showed that DEGs are in different growth cycle periods, and enriched GO items are mostly related to the transformation of cell and protein. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment result indicated that metabolic process has a great impact on SHF growth cycle. Based on the results of a comprehensive analysis of differentially expressed genes, GO enrichment and KEGG enrichment, we found that FGF5, FGFR1 and RRAS had an effect on the hair follicle growth cycle. The results of this study may provide a theoretical basis for further research on the growth and development of SHF in Inner Mongolian Cashmere goats.
