Abstract Background Cellular and cell-derived components of adipose-derived tissue for the purposes of dermatologic and aesthetic rejuvenation applications have become increasingly studied and integrated into clinical practice. The hair follicle goes through phases of growth, regression, and quiescence, and it is suspected that adipocytes secrete factors to promote activation of hair follicles dermal papilla cells, increasing migration, and proliferation in vitro; as well as increasing conversion of hair follicles from the telogen to anagen phase in vivo. Objectives Evaluation of efficacy and safety of adipose-derived adult stem cells (ADSCs) injection in hair follicle regeneration in female pattern hair loss (FPHL). Methods 33 patients were included and divided into 3 groups according to Sinclair’s classification according to severity. ADSCs were extracted from lipoaspirate and injected into the frontoparietal scalp. Patients were assessed clinically, trichoscopically and immunohistochemically. Results At week 24, there was improvement of hair thickness and count, both in frontal and occipital areas. Histopathological and immunohistochemical assessment at week 12 showed decrease of perifollicular inflammation and decrease of DKK-1 immunostaining. Conclusion The use of ADSCs in treatment of FPHL in subjects included in this study showed improvement of perifollicular inflammation, in addition to density and thickness of hair.

We have examined the expression of smooth muscle alpha-actin in hair follicles in situ, and in hair follicle dermal cells in culture by means of immunohistochemistry. Smooth muscle alpha-actin was present in the dermal sheath component of rat vibrissa, rat pelage and human follicles. Dermal papilla cells within all types of follicles did not express the antigen. However, in culture a large percentage of both hair dermal papilla and dermal sheath cells were stained by this antibody. The same cells were negative when tested with an antibody to desmin. Overall, explant-derived skin fibroblasts had relatively low numbers of positively marked cells, but those from skin regions of high hair-follicle density displayed more smooth muscle alpha-actin expression than fibroblasts from areas with fewer follicles. 2-D SDS-PAGE confirmed that, unlike fibroblasts, cultured papilla cells contained significant quantities of the alpha-actin isoform. The rapid switching on of smooth muscle alpha-actin expression by dermal papilla cells in early culture, contrasts with the behaviour of smooth muscle cells in vitro, and has implications for control of expression of the antigen in normal adult systems. The very high percentage of positively marked cultured papilla and sheath cells also provides a novel marker of cells from follicle dermis, and reinforces the idea that they represent a specialized cell population, contributing to the heterogeneity of fibroblast cell types in the skin dermis, and possibly acting as a source of myofibroblasts during wound healing.

AbstractHair regenerative medicine has emerged as a promising approach for the treatment of severe hair loss. Recent advances in three-dimensional tissue engineering, such as formation of hair follicle germs (HFGs), have considerably improved hair regeneration after transplantation in animal models. Here, we proposed an approach for fabricating HFGs containing vascular endothelial cells. Epithelial, dermal papilla, and vascular endothelial cells initially formed a single aggregate, which subsequently became a dumbbell-shaped HFG, wherein the vascular endothelial cells localized in the region of dermal papilla cells. The HFGs containing vascular endothelial cells exhibited higher expression of hair morphogenesis-related genes in vitro, along with higher levels of hair shaft regeneration upon transplantation to the dorsal side of nude mice, than those without vascular endothelial cells. The generated hair follicles represented functional characteristics, such as piloerection, as well as morphological characteristics comparable to those of natural hair shafts. This approach may provide a promising strategy for fabricating tissue grafts with higher hair inductivity for hair regenerative medicine.

Parallel cultures of adult rat vibrissa dermal papilla cells and skin fibroblasts revealed differences between the two cell types with respect to a number of criteria. In particular the dermal papilla cells demonstrated a distinctive single cell morphology, and at confluence formed cell aggregates radically different from regular fibroblast multilayering and patterning. This finding confirmed repeated observations of papilla cell clumping in short-term culture. The dermal papilla cells which are mitotically quiescent in situ were also shown to have a lower proliferative capacity than the skin fibroblasts. The affinity shown by papilla cells towards each other in culture reflected the behaviour demonstrated by isolated dermal papillae transplanted into ear dermis and into the collagenous capsule of the vibrissa follicle. In the absence of epidermal contact the papilla cells remained as recognizable rounded aggregates for the experimental period of up to nine months. Synthesis of extracellular material typical of that seen in situ was observed, particularly during the first weeks following transplantation. The collective behaviour of the dermal papilla cells revealed in this study may be significant for the morphogenetic activity of the papilla, and for papilla size during the hair cycle. It may also reflect the retention of embryonic-like properties by the dermal component of adult hair follicles.

Porphyra-334 is a kind of mycosporine-like amino acid absorbing ultraviolet-A. Here, we characterized porphyra-334 as a potential antiaging agent. An in vitro assay revealed that porphyra-334 dramatically promoted collagen synthesis in fibroblast cells. The effect of porphyra-334 on cell proliferation was dependent on the cell type, and the increase of cell viability by porphyra-334 was the highest in keratinocyte cells among the three tested cell types. An in vivo clinical test with 22 participants demonstrated the possible role of porphyra-334 in the improvement of periorbital wrinkles. RNA-sequencing using human follicle dermal papilla (HFDP) cells upon porphyra-334 treatment identified the upregulation of metallothionein- (MT-) associated genes, confirming the antioxidant role of porphyra-334 with MT. Moreover, the expression of genes involved in nuclear chromosome segregation and the encoding of components of kinetochores was upregulated by porphyra-334 treatment. Furthermore, we found that several genes associated with the hair follicle cycle, the hair follicle structure, the epidermal structure, and stem cells were upregulated by porphyra-334 treatment, suggesting the potential role of porphyra-334 in hair follicle growth and maintenance. In summary, we provided several new pieces of evidence of porphyra-334 as a potential antiaging cosmetic agent and elucidated the expression network in HFDP cells upon porphyra-334.

Abstract IntroductionDermal papilla cells (DPc) is an important element in studying the hair follicle (HF) niche. The human hair follicle dermal papilla cells (HFDPC) are widely used as an in vitro model to study hair growth related research. These cells are usually grown in 2D culture, nevertheless, this system did not show efficient therapeutic effect on HF regeneration and growth, and key differences were observed between cell activity in vitro and in vivo. ObjectiveRecent studies have showed that HFDPC grown in 3D hanging spheroids is more morphologically akin to intact DPc microenvironment. This current study showed that the 3D model is applicable to the commercial cell line with new insights on its variability by comparing to previous studies of gene signature restored by 3D culture.Methods and Results Our data demonstrated that HFDPCS grown in 3D in vitro model can influence not only hair growth-related pathways but also immune system -related pathways compared to 2D cell monolayer. Furthermore, we compared the expression of signalling molecules and metabolism-associated proteins of HFDPC in minoxidil (FDA approved drug for hair loss treatment) and 3,4,5-tri-O-caffeoylquinic acid (TCQA) (recently found to induce hair growth in vitro and in vivo) treated 3D and 2D cell cultures using microarray analysis. Conclusion Further validation of the results confirms the suitability of this cell line for 3D model while providing new insights such as to the mechanisms behind the hair growth effects of 3D spheroid treated with hair growth promoting agents.

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.

Androgens can gradually transform large scalp hair follicles to smaller vellus ones, causing balding. The mechanisms involved are unclear, although androgens are believed to act on the epithelial hair follicle via the mesenchyme-derived dermal papilla. This study investigates whether the levels and type of androgen receptors in primary lines of cultured dermal papilla cells derived from balding scalp hair follicles differ from those of follicles from non-balding scalp. Androgen receptor content was measured by saturation analysis using the non-metabolisable androgen, [3H]mibolerone (0.05-10 nM) in a 9-10 point assay. Pubic dermal fibroblasts and Shionogi cells were examined as positive controls. Repetitive assays of Shionogi cells showed good precision in the levels of androgen receptor content (coefficient of variation = 3.7%). Specific, high affinity, low capacity androgen receptors were detected in dermal papilla cells from both balding and non-balding follicles. Balding cells contained significantly (P < 0.01) greater levels of androgen receptors (Bmax = 0.06 +/- 0.01 fmol/10(4) cells (mean +/- S.E.M.)) than those from non-balding scalp (0.04 +/- 0.001). Competition studies with a range of steroids showed no differences in receptor binding specificity in the two cell types. The higher levels of androgen receptors in cells from balding scalp hair follicles with similar properties to those from non-balding scalp concur with the expectations from their in vivo responses to androgens. This supports the hypothesis that androgens act via the dermal papilla and suggests that cultured dermal papilla cells may offer a model system for studying androgen action in androgenetic alopecia.

ABSTRACT Androgens stimulate hair growth in many areas, e.g. the beard; they also induce regression and balding on the scalp with increasing age in genetically disposed individuals. The cause(s) of this biological conundrum is unknown but age-related; androgen-potentiated changes also occur in the prostate. The mesenchymederived dermal papilla situated at the base of the hair follicle is thought to play an important role in regulating the growth and development of the follicular epithelium. Since androgens probably act on the hair follicle via the dermal papilla, cultures of dermal papilla cells from human hair follicles with differing responses to androgens in vivo have been established and their ability to bind androgens assessed. Receptor binding was assayed by saturation analysis (0·05–10 nmol/l) using the synthetic non-metabolizable androgen, [3H]mibolerone. Shionogi 115 cells were also assayed as a positive control. Specific high-affinity low-capacity androgen receptors were identified in 12 dermal papilla primary cell lines with similar characteristics to established androgen receptors. Cells from androgen-sensitive follicles (beard, scrotum and pubis) contained higher levels of androgen receptors than those derived from relatively androgeninsensitive non-balding scalp follicles whether the receptor content was calculated in relation to cell number, protein or DNA content of the cells. These results support the hypothesis that androgens act on hair follicles via the dermal papilla in vivo and demonstrate that dermal papilla cells exhibit an altered phenotype in culture which depends on the body site from which they were derived. Cultured human dermal papilla cells should prove a useful model system for studies of the mechanism of androgen action, and further investigations may elucidate the paradox of why bald men can grow beards.
