Abstract
Dermal papilla cells (DPCs) is the key dermal component of the hair follicle that directly regulates hair follicle development, growth and regeneration. Successfully isolated and cultured DPCs of Rex rabbit could provide a good model for the study of hair follicle development mechanism in vitro. Skin samples were collected from 30-day old Rex rabbits and separated by combination of Dispase II and Collagenase D, separation, culture, and purification of DPCs. The morphology of DPCs in vitro was observed and the growth curve was drawn, the number of DPCs presented progressive increase in a logarithmic model between the 4th day and the 7th day. The results of immune chemical and immune fluorescence shown that α smooth muscle actin (α-SMA) and versican were positive in cells. Growth character of the passages 3 (P3), P6, P9 and P12 DPCs were observed using MTT at 24 h, 48 h, 72 h, 96 h, 120 h and 144 h. The cell density of P12 was lower than P3 (P < 0.05); the flow cytometric analysis showed that DPCs at resting state/first gap (G0/G1) stage of P3 was higher than P12 (P < 0.05), and second gap/mitosis (G2/M) stage of P3 was lower than P12 (P < 0.05). However, the DPCs of P12 present triangular or short fusiform, retaining their unique aggregative growth characteristics. This results shown that the DPCs properties of P12 from Rex rabbits, still fit functional research in vitro. In conclusion, we successfully established the culturing condition of DPCs from Rex rabbits, and provide a material for studying the molecular mechanism of hair follicle development.

Abstract
De novo skin regeneration with human keratinocytes amplified in culture is a life-saving procedure for patients with extensive skin loss and chronic wounds. It also provides a valuable platform for gene function and therapeutic assessments. Nevertheless, tissues generated in this manner lack hair follicles that are important for skin homeostasis, barrier function, and repair. In this study, we generated skin tissues with human keratinocytes combined with dermal papilla (DP) cells isolated from mouse whisker hair. For this, cultured keratinocytes and mouse DP (mDP) cells were mixed at 10:1 ratio and seeded onto devitalized human dermal matrix derived from surgically discarded human abdominoplasty skin. After 1 week in submerged culture, the cell/matrix composites were grafted onto the skin wound beds of immunocompromised NSG.SCID mice. Histological analysis of 6-week-old skin grafts showed that tissues generated with the addition of mDP cells contained Sox2-positive dermal condensates and well-differentiated folliculoid structures that express human keratinocyte markers. These results indicate that cultured mDP cells can induce hair follicle neogenesis in the de novo regenerated skin tissues. Our method offers a new experimental system for mechanistic studies of hair follicle morphogenesis and tissue regeneration and provides insights to solving an important clinical challenge in generation of fully functional skin with a limited source of donor cells.

Role of Annexin A2 isoform 2 on the aggregative growth of dermal papillae cells. Biosci Rep 2018; 38:BSR20180971. [PMID: 30341243 PMCID: PMC6435533 DOI: 10.1042/bsr20180971] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Revised: 09/25/2018] [Accepted: 10/09/2018] [Indexed: 12/14/2022] Open
Abstract
The dermal papilla is a major component of hair, which signals the follicular epithelial cells to prolong the hair growth process. Human Annexin A2 was preliminarily identified by two-dimensional gel electrophoresis (2-DE), MALDI-TOF-MS and database searching. The aim of the present study was to explore the role of Annexin A2 in the aggregative growth of dermal papillae cells (DPC). Reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were adopted to detect the expression of Annexin A2. And siRNA technique was used to suppress the expression of Annexin A2. Construction of over-expression vector was used to up-regulate the expression of Annexin A2. Cell Counting Kit 8 (CCK-8) and proliferating cell nuclear antigen (PCNA) were taken to detect the proliferation of DPC. The expression of Annexin A2 mRNA was up-regulated in passage 3 DPC compared with passage 10 DPC by RT-PCR. In line with the results at the mRNA level, Western blot analysis revealed that Annexin A2 isoform 2 was up-regulated significantly in passage 3 DPC compared with passage 10 DPC. The Annexin A2 isoform 2 siRNA was synthesized and transfected into passage 3 DPC. RT-PCR data showed the mRNA expression of Annexin A2 isoform 2 was suppressed in passage 3 DPC. Western blot results showed the expression level of Annexin A2 isoform 2 and PCNA were suppressed in passage 3 DPC. CCK-8 results showed that the proliferation of passage 3 DPC was suppressed (P < 0.05). Recombinant plasmid PLJM-Annexin A2 isoform 2-expression vector were constructed and were transfected into passage 10 DPC. RT-PCR data showed the mRNA expression of Annexin A2 isoform 2 was up-regulated in passage 10 DPC. Western blot results showed the expression level of annexin A2 isoform 2 and PCNA were up-regulated in passage 10 DPC. CCK-8 assay showed the proliferation of DPC was stimulated compared with control group (*P < 0.05). Our study proved that Annexin A2 isoform 2 may participate in regulating the proliferation of DPC and may be related to aggregative growth of dermal papilla cells. Therefore, our study suggests that Annexin A2 may be linked to hair follicle growth cycle.

Abstract
Objective Dermal papilla and hair epithelial stem cells regulate hair formation and
the growth cycle. Damage to or loss of these cells can cause hair loss. Although
several studies claim to reconstitute hairs using rodent cells in an animal model,
additional research is needed to develop a stable human hair follicle reconstitution
protocol. In this study, we have evaluated hair induction by injecting adult cultured
human dermal papilla cells and a mixture of hair epithelial and dermal papilla cells in
a mouse model.
Materials and Methods In this experimental study, discarded human scalp skins were
used to obtain dermal papilla and hair epithelial cells. After separation, cells were cultured
and assessed for their characteristics. We randomly allocated 15 C57BL/6 nude mice into
three groups that received injections in their dorsal skin. The first group received cultured
dermal papilla cells, the second group received a mixture of cultured epithelial and dermal
papilla cells, and the third group (control) received a placebo [phosphate-buffered saline
(PBS-)].
Results Histopathologic examination of the injection sites showed evidence of hair
growth in samples that received cells compared with the control group. However, the
group that received epithelial and dermal papilla cells had visible evidence of hair growth.
PKH tracing confirmed the presence of transplanted cells in the new hair.
Conclusion Our data showed that injection of a combination of adult human cultured
dermal papilla and epithelial cells could induce hair growth in nude mice. This study emphasized that the combination of human adult cultured dermal papilla and epithelial cells
could induce new hair in nude mice.

Abstract
The particular combination of polydeoxyribonucleotides, l-carnitine, calcium ions, proteolytic enzyme and other ingredients acts in a synergetic way in the regeneration of skin and connective tissues. This new formulation of active principles was tested in vitro as a cell and tissue culture medium and in vivo for various preparations in support of tissue regeneration. In vitro, the new blend allowed the maintenance of skin biopsies for more than 1 year in eutrophic conditions. Immunocytochemical analyses of fibroblasts isolated from these biopsies confirmed a significant increase of the epidermal and connective wound-healing markers such as collagen type I, collagen type IV, cytokeratin 1 (CK1), CK5, CK10 and CK14 versus controls. To examine the effects of the new compound in vivo, we studied impaired wound healing in genetically diabetic db/db mice. At day 18, diabetic mice treated with the new composition showed 100% closure of wounds and faster healing than mice treated with the other solutions. This complex of vital continuity factors or life-keeping factors could be used as a tissue-preserving solution or a cosmetic/drug/medical device to accelerate wound healing in the treatment of patients with deficient wound repair to promote the regeneration of cutaneous and connective tissues (injuries-wound, dermatitis) and prevent the recurrent relapses.

Abstract
The vibrissal follicle-sinus complex (FSC) is a sensory receptor of the mammalian integumentary system that is located around the mouth. The purpose of the present study was to identify the actual 3-dimensional structure of the rat vibrissal FSC. Rat skin tissue was serially sectioned at a thickness of 10 μm and then stained with Masson's trichrome. The serial sections were reconstructed 3-dimensionally using Reconstruct software. The rat vibrissal follicle is a spindle-shaped structure that is embedded within a blood sinus and enveloped within a thick collagenous capsule. The vibrissal FSC is innervated by the deep vibrissal and superficial vibrissal nerves. The deep vibrissal nerve, travelling in the basal-to-apical direction, penetrates the thick collagenous capsule of the vibrissal FSC. The sinus system can be divided into a superior portion, known as the ring sinus, and an inferior portion, known as the cavernous sinus. The ring sinus contains a C-shaped structure, the ringwulst, which is suspended from the mesenchymal sheath of the follicle. Collagenous trabeculae can be seen in the cavernous sinus but not in the ring sinus. The ring sinus encircles the follicle obliquely and asymmetrically. The ringwulst encircles the follicle incompletely, in a C-shaped fashion. This study has demonstrated the previously underappreciated 3-dimensional structure of the vibrissal FSC, which differs from previously reported descriptions, and provides data that will enhance the understanding of vibrissal function.

Abstract
Hair follicle morphogenesis and regeneration occur by an extensive and collaborative crosstalk between epithelial and mesenchymal skin components. A series of pioneering studies, which revealed an indispensable role of follicular dermal papilla and dermal sheath cells in this crosstalk, has led workers in the field to study in detail the anatomical distribution, functional properties, and molecular signature of the trichogenic dermal cells. The purpose of this paper was to provide a practical summary of the development and recent advances in the study of trichogenic dermal cells. Following a short review of the relevant literature, the methods for isolating and culturing these cells are summarized. Next, the bioassays, both in vivo and in vitro, that enable the evaluation of trichogenic properties of tested dermal cells are described in detail. A list of trichogenic molecular markers identified by those assays is also provided. Finally, this methods review is completed by defining some of the major questions needing resolution.

Abstract
BACKGROUND The dermal papilla is a major component of hair, which signals the follicular epithelial cells to prolong the hair growth process. To date, little is known about the significance of the specific protein(s) express in the dermal papilla cells (DPC) with regard to their aggregative behaviour. OBJECTIVES To identify proteins involved in aggregative behaviour of DPC, we comparatively analyzed the proteome of cells with and without aggregative behaviour. METHODS A series of methods were used, including two-dimensional gel electrophoresis (2-DE), PDQuest software analysis of 2-DE gels, peptide mass fingerprinting based on matrix-assisted laser desorption/ionisation-time of flight-mass spectrometry (MALDI-TOF-MS), and NCBInr database searching, to separate and identify differentially expressed proteins. Western blotting and reverse transcriptase polymerase chain reaction (RT-PCR) were used to validate the differentially expressed proteins. RESULTS Image analysis revealed that averages of 618+/-22 and 568+/-47 protein spots were detected in passages 3 and 10 DPC, respectively. Twenty-four differential protein spots were measured with MALDI-TOF-MS. A total of 17 spots yielded good spectra, and 15 spots matched with known proteins after database searching. Western blotting confirmed that heat shocking protein 70 was up-regulated in passage 3 DPC. Over-expression of mitochondrial ribosomal protein S7 was confirmed by RT-PCR, indicating that they are involved in aggregation of DPC through some signaling pathway. CONCLUSIONS The clues provided by the comparative proteome strategy utilized here will shed light on molecular mechanisms of DPC in aggregative behaviour.

Abstract
Wnts are deeply involved in the proliferation and differentiation of skin epithelial cells. We previously reported the differentiation of cultured primary skin epithelial cells toward hair shaft and inner root sheath (IRS) of the hair follicle via beta-catenin stabilization caused by Wnt-10b, however, the effects of Wnt-10b on cultured hair follicles have not been reported. In the present study, we examined the effects of Wnt-10b on shaft growth using organ cultures of whisker hair follicles in serum-free conditions. No hair shaft growth was observed in the absence of Wnt-10b, whereas its addition to the culture promoted elongation of the hair shaft, intensive incorporation of BrdU in matrix cells flanking the dermal papilla (DP), and beta-catenin stabilization in DP and IRS cells. These results suggest a promoting effect of Wnt-10b on hair shaft growth that is involved with stimulation of the DP via Wnt-10b/beta-catenin signalling, proliferation of matrix cells next to the DP, and differentiation of IRS cells by Wnt-10b.

Abstract
Alkaline phosphatase (ALP) activity was detected in the restricted mesenchymal and epithelial regions in mouse vibrissal follicles. Its localization and strength dramatically changed during the hair cycle. Activity in the dermal papilla (DP) was moderate in very early anagen, reached a maximal level in early anagen, decreased at the proximal region of DP after mid anagen, and was kept at a low level during catagen. The bulbar dermal sheath showed intense ALP activity only in early anagen. Although most bulbar epithelium did not show ALP activity, germinative epidermal cells that were adjacent to the ALP-negative DP cells became ALP-positive in mid anagen and rearranged in a single layer so as to encapsulate the DP in mid catagen. During catagen, the outermost layer of bulbar epithelium became ALP-positive, which could be follicular epithelial precursors migrating from the bulge. Before the initiation of hair formation, ALP activity in the bulbar epithelium rapidly decreased and that in DP increased. These dynamic changes of ALP expression might be related to DP's functions in hair induction and also to reconstruction of the bulbar structure during the hair cycle.

Abstract
The dermal papilla plays pivotal roles in hair follicle cycle and dermal papilla cells (DPCs) with aggregative behavior have more obviously inductive ability. In the present study, the suppression subtractive hybridization method was employed to identify the differentially expressed genes in dermal papillae cells with aggregative behavior. Following mRNA isolation of DPC with and without aggregative behavior, cDNA of both populations were prepared and subtracted by suppression PCR. Sequencing of enriched cDNAs identified five genes differentially expressed including capping protein, paladin, and vascular endothelial growth factor. Interestingly, HSPC016, first cloned from CD34+ hematopoietic stem/progenitor cells (HSPC), was identified by SSH, cDNA dot blot and Northern blot, which showed that this gene was differentially expressed in DPC with aggregative behavior. The full-length cDNA of HSPC016 was shown to be 366 bp, and the possible function of HSPC016 related to transcriptional regulation.

Abstract
Green fluorescent protein (GFP)-expressing wild-type, and nontransgenic mouse vibrissa follicle cells were cultured and implanted to mouse ears and footpads. Dermal papiller (DP)-derived cells and cells from the peribulbar dermal sheath "cup" (DSC) induced new hair follicles in both implanted ears and footpads, while nonbulbar dermal sheath cells did not. Confocal microscopy revealed that GFP-expressing DP and DSC cells induced hair growth associated with the formation of DP exclusively comprised of fluorescent cells. In mouse ears, but not footpads, fluorescent DP and DSC cells could also be identified in DP along with nonfluorescent cells. DSC cells were characterized in vivo and in vitro by low alkaline phosphatase activity in contrast to high alkaline phosphatase in DP cells. The results indicate transplanted DP and DSC cells were equally capable of DP formation and hair follicle induction. This suggests the DP and peribulbar DSC may be functionally similar. In addition to observing papillae exclusively composed of GFP-expressing cells, DP and DSC cells may also have combined with resident cells to form papillae composed of implanted GFP-expressing cells and host-derived non-GFP-expressing cells. Alkaline phosphatase expression may be utilized as a simple marker to identify hair follicle mesenchyme derived cells with hair follicle inductive abilities.

Abstract
Hair fiber production is the macroscopic end-point of a highly complex set of interactions between the hair follicle's epithelial and mesenchymal components. The nature of this relationship is largely set during hair follicle morphogenesis, but is dramatically revisited in the adult during the unique tissue remodeling events required for hair follicle cycling. Whereas significant attention has focused on the fate of the hair follicle epithelium during these events, associated changes in hair follicle fibroblast subpopulations remain unclear. Here, we present a speculative review that represents a critical and innovative synthesis of the current literature and summarizes a recently submitted original study by the authors, on the nature of hair cycle-dependent fibroblast dynamics and on how perturbations thereof may lead to several clinical manifestations of altered human hair growth.

Abstract
The continuously remodeled hair follicle is a uniquely exploitable epithelial-mesenchymal interaction system. In contrast to the cyclical fate of the hair follicle epithelium, the dynamics of the supposedly stable hair follicle mesenchyme remains enigmatic. Here we address this issue using the C57BL/6 hair research model. During hair growth, increase in total follicular papilla size was associated with doubling of papilla cell numbers, much of which occurred before intra-follicular papilla cell proliferation, and subsequent to mitosis in the proximal connective tissue sheath. This indicates that some papilla cells originate in, and migrate from, the proliferating pool of connective tissue sheath fibroblasts. Follicular papilla cell number and total papilla size were maximal by anagen VI, but intriguingly, decreased by 25% during this period of sustained hair production. This cell loss, which continued during catagen, was not associated with intra-follicular papilla apoptosis, strongly indicating that fibroblasts migrate out of the late anagen/early catagen papilla and re-enter the proximal connective tissue sheath. Low-level apoptosis occurred only here, along with the "detachment" of cells from the regressing connective tissue sheath. Thus, the hair follicle mesenchyme exhibits significant hair cycle-associated plasticity. Modulation of these cell interchanges is likely to be important during clinically important hair follicle transformations, e.g. vellus-to-terminal and terminal-to-vellus during androgenetic alopecia.

Abstract
Hair growth depends on maintenance of signalling between the dermal papilla and the germinative epithelium (GE), from which the differentiated layers of the hair fibre originate. Because no molecular studies have been reported which concentrate specifically on GE cells either in vivo or in vitro, we prepared a cDNA library enriched for messages which were highly expressed in GE cells to identify genes that may be involved in hair growth control. Of 35 subtracted library clones sequenced, 23 shared extensive homology with previously determined cDNA sequences, including LEF-1 and id4. Hair follicle organ culture models are often used to investigate the molecular basis of hair growth, although hair growth arrest occurs relatively rapidly in vitro. As an indicator of their role in follicle activities, we compared the expression of GE-specific clones in different regions of freshly isolated vibrissa follicles, with the corresponding regions of growth arrested, cultured follicles. Changes in the expression of some of these clones indicates that they could be related to fundamental cellular activities in the follicle. A library enriched for GE-specific clones therefore provides a useful source of candidate molecules for studies of follicular epithelial cell behaviour, both in vivo and in vitro.
