Abstract
Hair loss disorder (alopecia) affects numerous people around the world. The low effectiveness and numerous side effects of common treatments have prompted researchers to investigate alternative and effective solutions. Hair follicle (HF) bioengineering is the knowledge of using hair-inductive (trichogenic) cells. Most bioengineering-based approaches focus on regenerating folliculogenesis through manipulation of regulators of physical/molecular properties in the HF niche. Despite the high potential of cell therapy, no cell product has been produced for effective treatment in the field of hair regeneration. This problem shows the challenges in the functionality of cultured human hair cells. To achieve this goal, research and development of new and practical approaches, technologies and biomaterials are needed. Based on recent advances in the field, this review evaluates emerging HF bioengineering strategies and the future prospects for the field of tissue engineering and successful HF regeneration.

Abstract
Topical minoxidil (5% foam, 5% solution, and 2% solution) is FDA-approved for androgenetic alopecia (AGA) in men and women.Mechanism of action: Minoxidil acts through multiple pathways (vasodilator, anti-inflammatory agent, inducer of the Wnt/β-catenin signaling pathway, an antiandrogen), and may also affect the length of the anagen and telogen phases.Pharmacokinetics: Approximately 1.4% of topical minoxidil is absorbed through the skin. Minoxidil is a prodrug that is metabolized by follicular sulfotransferase to minoxidil sulfate (active form). Those with higher sulfotransferase activity may respond better than patients with lower sulfotransferase activity.Clinical efficacy (topical minoxidil): In a five-year study, 2% minoxidil exhibited peak hair growth in males at year one with a decline in subsequent years. Topical minoxidil causes hair regrowth in both frontotemporal and vertex areas. The 5% solution and foam were not significantly different in efficacy from the 2% solution.Oral and Sublingual minoxidil (not FDA approved; off-label): After 6 months of administration, minoxidil 5 mg/day was significantly more effective than topical 5% and 2% in male AGA. Low-dose 0.5-5 mg/day may also be safe and effective for female pattern hair loss and chronic telogen effluvium. Sublingual minoxidil may be safe and effective in male and female pattern hair loss.

Abstract
Tissue engineering (TE) is a multidisciplinary research field aiming at the regeneration, restoration, or replacement of damaged tissues and organs. Classical TE approaches combine scaffolds, cells and soluble factors to fabricate constructs mimicking the native tissue to be regenerated. However, to date, limited success in clinical translations has been achieved by classical TE approaches, because of the lack of satisfactory biomorphological and biofunctional features of the obtained constructs. Developmental TE has emerged as a novel TE paradigm to obtain tissues and organs with correct biomorphology and biofunctionality by mimicking the morphogenetic processes leading to the tissue/organ generation in the embryo. Ectodermal appendages, for instance, develop in vivo by sequential interactions between epithelium and mesenchyme, in a process known as secondary induction. A fine artificial replication of these complex interactions can potentially lead to the fabrication of the tissues/organs to be regenerated. Successful developmental TE applications have been reported, in vitro and in vivo, for ectodermal appendages such as teeth, hair follicles and glands. Developmental TE strategies require an accurate selection of cell sources, scaffolds and cell culture configurations to allow for the correct replication of the in vivo morphogenetic cues. Herein, we describe and discuss the emergence of this TE paradigm by reviewing the achievements obtained so far in developmental TE 3D scaffolds for teeth, hair follicles, and salivary and lacrimal glands, with particular focus on the selection of biomaterials and cell culture configurations.

Abstract
Female pattern hair loss (FPHL) is nonscarring progressive thinning of hair with gradual decrease in the number of hair, especially in the frontal, central, and parietal scalp, due to a process known as follicular miniaturization. The etiopathogenesis of FPHL is complex with multiple factors such as genetics, inflammation, hormones, and environment playing role in it. It usually manifests as slowly progressive hair thinning, mainly over the vertex and upper parietal scalp, the frontal hairline is often spared and the miniaturization is also not as severe as in men. A thorough history, clinical examination, hair loss evaluation tests, dermoscopy, and scalp biopsy can help in establishing the diagnosis. Various biochemical tests may be needed in patients with hyperandrogenism. The treatment includes medical and surgical modalities. Topical minoxidil is still considered the first line of treatment. Along with medical therapy, cosmetic camouflage may also be needed in some cases.

Abstract
Inula helenium (IH) is known to possess antifungal, anti-bacterial, anti-helminthic, and anti-proliferation activities. Caesalpinia Sappan (CS) is known to reduce inflammation and improve blood circulation. Based on their folkloric use, these plants are expected to be promising candidates for promoting hair growth and preventing hair loss. Moreover, these plants are rich sources of certain phytochemicals, which have been reported to promote hair growth. In this clinical trial, we investigate the efficacy of a scalp shampoo formulated by mixing extracts of IH and CS in preventing hair loss and promoting hair growth in patients with androgenetic alopecia. Using a phototrichogram (Folliscope 2.8, LeadM, Korea), we compared the hair density and total hair counts in patients receiving the scalp shampoo at baseline, and at 8, 16, and 24 weeks after use of the shampoo. We found a statistically significant increase in the total hair count in the test group (n = 23) after 16 and 24 weeks of using the scalp shampoo (2.17 n/cm2 ± 5.72, p < 0.05; and 4.30 n/cm2 ± 6.37, p < 0.01, respectively) as compared to the control subjects. Based on the results of this clinical study, we conclude that the IH and CS extract complex is a promising remedy for preventing hair loss and promoting hair growth.

Abstract
Hair follicles develop from the ectoderm in embryos and cyclically regenerate using proper spatiotemporal signaling molecules, which are conserved in organogenesis during adulthood. Previously, we demonstrated that bioengineered hair follicle germs could regenerate functional hair follicles via a three-dimensional cell manipulation technique, which we named the "organ germ method ." We could also regulate the type of hair follicle and pigmentation with correct structures by rearranging the source of the cells. In this article, we describe a detailed protocol for the regeneration of functional hair follicles and their stem cell niches by the rearrangement of embryonic or adult hair follicle-derived epithelial and mesenchymal cells.

Abstract
BACKGROUND Androgenetic alopecia is a condition with a high prevalence worldwide and affects both males and females. Currently, only 2 approved treatments exist: finasteride (males only) and minoxidil 2 or 5% solution (males and females). METHODS We conducted a randomized, open-label, multicenter noninferiority study to determine whether a caffeine-based 0.2% topical liquid would be no less effective than minoxidil 5% solution in males (n = 210) with androgenetic alopecia. The primary end point was the percentage change in the proportion of anagen hairs from baseline to 6 months using a frontal and occipital trichogram. RESULTS At 6 months, the group of the 5% minoxidil solution showed a mean improvement in anagen ratio of the trichogram of 11.68%, and the group of the 0.2% caffeine solution had an anagen improvement of 10.59%. The difference of mean values between both groups was 1.09%. The statistical analysis was performed and reported in accordance with the CONSORT Guidelines 2010 for reporting of noninferiority and equivalence randomized trials. CONCLUSION A caffeine-based topical liquid should be considered as not inferior to minoxidil 5% solution in men with androgenetic alopecia.

Abstract
Bioengineering hair follicles using cells isolated from human tissue remains a difficult task. Dermal papilla (DP) cells are known to guide the growth and cycling activities of hair follicles by interacting with keratinocytes. However, DP cells quickly lose their inductivity during in vitro passaging. Rodent DP cell cultures need external addition of growth factors, including WNT and BMP molecules, to maintain the hair inductive property. CD133 is expressed by a subpopulation of DP cells that are capable of inducing hair follicle formation in vivo. We report here that expression of a stabilized form of β-catenin promoted clonal growth of CD133-positive (CD133+) DP cells in in vitro three-dimensional hydrogel culture while maintaining expression of DP markers, including alkaline phosphatase (AP), CD133, and integrin α8. After a 2-week in vitro culture, cultured CD133+ DP cells with up-regulated β-catenin activity led to an accelerated in vivo hair growth in reconstituted skin compared to control cells. Further analysis showed that matrix cell proliferation and differentiation were significantly promoted in hair follicles when β-catenin signaling was up-regulated in CD133+ DP cells. Our data highlight an important role for β-catenin signaling in promoting the inductive capability of CD133+ DP cells for in vitro expansion and in vivo hair follicle regeneration, which could potentially be applied to cultured human DP cells.

Abstract
Human dermal papilla (DP) cells have been studied extensively when grown in the conventional monolayer. However, because of great deviation from the real in vivo three-dimensional (3D) environment, these two-dimensional (2D) grown cells tend to lose the hair-inducible capability during passaging. Hence, these 2D caused concerns have motivated the development of novel 3D culture techniques to produce cellular microtissues with suitable mimics. The hanging-drop approach is based on surface tension-based technique and the interaction between surface tension and gravity field that makes a convergence of liquid drops. This study used this technique in a converged drop to form cellular spheroids of dermal papilla cells. It leads to a controllable 3Dspheroid model for scalable fabrication of inductive DP microtissues. The optimal conditions for culturing high-passaged (P8) DP spheroids were determined first. Then, the morphological, histological and functional studies were performed. In addition, expressions of hair-inductive markers including alkaline phosphatase, α-smooth muscle actin and neural cell adhesion molecule were also analyzed by quantitative RT-PCR, immunostaining and immunoblotting. Finally, P8-DP microtissues were coimplanted with newborn mouse epidermal cells (EPCs) into nude mice. Our results indicated that the formation of 3D microtissues not only endowed P8-DP microtissues many similarities to primary DP, but also confer these microtissues an enhanced ability to induce hair-follicle (HF) neogenesis in vivo. This model provides a potential to elucidate the native biology of human DP, and also shows the promising for the controllable and scalable production of inductive DP cells applied in future follicle regeneration.

Abstract
Hair follicle morphogenesis is first induced by epithelial-mesenchymal interactions in the developing embryo. In the hair follicle, various stem-cell populations are maintained in specialized niches to promote repetitive hair follicle-morphogenesis, which is observed in the variable lower region of the hair follicle as a postnatal hair cycle. In contrast, the genesis of most organs is induced only once during embryogenesis. We developed a novel bioengineering technique, the Organ Germ Method, that employs three-dimensional stem cell culture for regenerating various organs and reproducing embryonic organogenesis. In this chapter, we describe a protocol for hair follicle germ reconstitution using adult follicle-derived epithelial stem cells and dermal papilla cells with intracutaneous transplantation of the bioengineered hair-follicle organ germ. This protocol can be useful not only for the clinical study of hair regeneration but also for studies of stem cell biology and organogenesis.

Abstract
The hair follicle is a regenerating organ that produces a new hair shaft during each growth cycle. Development and cycling of the hair follicle is governed by interactions between the epithelial and mesenchymal components. Therefore, development of an engineered 3D hair follicle would be useful for studying these interactions to identify strategies for treatment of hair loss. We have developed a technique suitable for assembly of different cell types in close proximity in fibrous hydrogel scaffolds with resolutions of ∼50 μm. By assembly of dermal papilla (DP) and keratinocytes, structures similar to the native hair bulb arrangement are formed. Gene expression of these constructs showed up-regulation of molecules involved in epithelial-mesenchymal interactions of the hair follicle. Implantation of the follicular structures in SCID mice led to the formation of hair follicle-like structures, thus demonstrating their hair inductive ability. The transparency of the fiber matrix and the small dimensions of the follicular structures allowed the direct quantitation of DP cell proliferation by confocal microscopy, clearly illustrating the promoting or inhibitory effects of hair growth regulating agents. Collectively, our results suggested a promising application of these 3D engineered follicular structures for in vitro screening and testing of drugs for hair growth therapy.

Abstract
Hair follicle transplantation is often used in the treatment of androgenetic alopecia (AGA). However, the only source of hair follicles is from human donors themselves, which limits the application of this approach. One possible solution is to reconstitute hair follicle from dissociated cells. Currently, a number of microscale technologies have been developed to create size and shape controlled microenvironments in tissue engineering. Photopolymerizable PEGDA hydrogels are often selected as promising scaffolds in engineered microtissues due to their biocompatibility and adjustable mechanical properties. Here, we fabricated an array of PEGDA microwells with center islets that mimic the architecture of human hair follicles using soft lithography. Dermal and epithelial cells were seeded in different compartments of the microstructured mould to mimic mesenchymal and epithelial compartmentalization in native hair follicles. We demonstrated that these compartmentalized microstructures support cell proliferation and cell survival over 14 days, and spreading of dermal fibroblasts was observed. This hydrogel micromould provides a potentially useful tool for engineering 3D hair follicle-mimicking complex cultures in vitro.

Abstract
Hair follicle morphogenesis and regeneration depend on intensive but well-orchestrated interactions between epithelial and mesenchymal components. Accordingly, the enhancement of this crosstalk represents a promising approach to achieve successful bioengineering of human hair follicles. The present article summarizes the techniques, both currently available and potentially feasible, to promote epithelial-mesenchymal interactions (EMIs) necessary for human hair follicle regeneration. The strategies include the preparation of epithelial components with high receptivity to trichogenic dermal signals and/or mesenchymal cell populations with potent hair inductive capacity. In this regard, bulge epithelial stem cells, keratinocytes predisposed to hair follicle fate or keratinocyte precursor cells with plasticity may provide favorable epithelial cell populations. Dermal papilla cells sustaining intrinsic hair inductive capacity, putative dermal papilla precursor cells in the dermal sheath/neonatal dermis or trichogenic dermal cells derived from undifferentiated stem/progenitor cells are promising candidates as hair inductive dermal cells. The most established protocol for in vivo hair follicle reconstitution is co-grafting of epithelial and mesenchymal components into immunodeficient mice. In theory, combination of individually optimized cellular components of respective lineages should elicit most intensive EMIs to form hair follicles. Still, EMIs can be further ameliorated by the modulation of non-cell autonomous conditions, including cell compartmentalization to replicate the positional relationship in vivo and humanization of host environment by preparing human stromal bed. These approaches may not always synergistically intensify EMIs, however, step-by-step investigation probing optimal combinations should maximally enhance EMIs to achieve successful human hair follicle bioengineering.

Abstract
Well-orchestrated epithelial-mesenchymal interactions are crucial for hair follicle (HF) morphogenesis. In this study, ectodermal precursor cells (EPCs) with the capacity to cross talk with hair-inductive dermal cells were generated from human induced pluripotent stem cells (hiPSCs) and assessed for HF-forming ability in vivo. EPCs derived from three hiPSC lines generated with 4 or 3 factors (POU5F1, SOX2, KLF4 +/- MYC) mostly expressed keratin 18, a marker of epithelial progenitors. When cocultured with human dermal papilla (DP) cells, a 4 factor 201B7 hiPSC-EPC line upregulated follicular keratinocyte (KC) markers more significantly than normal human adult KCs (NHKCs) and other hiPSC-EPC lines. DP cells preferentially increased DP biomarker expression in response to this line. Interestingly, 201B7 hiPSCs were shown to be ectodermal/epithelial prone, and the derived EPCs were putatively in a wingless-type MMTV integration site family (WNT)-activated state. Importantly, co-transplantation of 201B7 hiPSC-EPCs, but not NHKCs, with trichogenic mice dermal cells into immunodeficient mice resulted in HF formation. Human HF stem cell markers were detected in reconstituted HFs; however, a low frequency of human-derived cells implied that hiPSC-EPCs contributed to HF morphogenesis via direct repopulation and non-cell autonomous activities. The current study suggests a, to our knowledge, previously unrecognized advantage of using hiPSCs to enhance epithelial-mesenchymal interactions in HF bioengineering.

Human mesenchymal stromal cells could deliver erythropoietin and migrate to the basal layer of hair shaft when subcutaneously implanted in a murine model. Tissue Cell 2012; 44:249-56.

Abstract
Mesenchymal stromal cells (MSC) are an attractive cell-targeting vehicle for gene delivery. MIDGE (an acronym for Minimalistic, Immunologically Defined Gene Expression) construct is relatively safer than the viral or plasmid expression system as the detrimental eukaryotic and prokaryotic gene and sequences have been eliminated. The objective of this study was to test the ability of the human MSC (hMSC) to deliver the erythropoietin (EPO) gene in a nude mice model following nucleofection using a MIDGE construct. hMSC nucleofected with MIDGE encoding the EPO gene was injected subcutaneously in Matrigel at the dorsal flank of nude mice. Subcutaneous implantation of nucleofected hMSC resulted in increased hemoglobin level with presence of human EPO in the peripheral blood of the injected nude mice in the first two weeks post-implantation compared with the control groups. The basal layer of the hair shaft in the dermal layer was found to be significantly positive for immunohistochemical staining of a human EPO antibody. However, only a few basal layers of the hair shaft were found to be positively stained for CD105. In conclusion, hMSC harboring MIDGE-EPO could deliver and transiently express the EPO gene in the nude mice model. These cells could be localized to the hair follicle and secreted EPO protein might have possible role in hair regeneration.

Abstract
Organ replacement regenerative therapy is purported to enable the replacement of organs damaged by disease, injury or aging in the foreseeable future. Here we demonstrate fully functional hair organ regeneration via the intracutaneous transplantation of a bioengineered pelage and vibrissa follicle germ. The pelage and vibrissae are reconstituted with embryonic skin-derived cells and adult vibrissa stem cell region-derived cells, respectively. The bioengineered hair follicle develops the correct structures and forms proper connections with surrounding host tissues such as the epidermis, arrector pili muscle and nerve fibres. The bioengineered follicles also show restored hair cycles and piloerection through the rearrangement of follicular stem cells and their niches. This study thus reveals the potential applications of adult tissue-derived follicular stem cells as a bioengineered organ replacement therapy. Bioengineered hair follicles can be produced from embryonic follicle germ cells, but whether these follicles can interact with the surrounding tissue and function normally is unknown. Here, bioengineered hair follicles transplanted into mouse dermis make connections with the surrounding tissue and show normal hair cycles.

Abstract
Introduction: Emerging regenerative medicine technologies have yet to be utilized in hair restoration surgery. Urinary bladder extracellular matrix (UBM) has shown promise in a wide variety of applications, inducing site-specific remodeling of injured tissue. This case series describes one clinician's experience in the first use of this regenerative material in hair restoration surgery. Materials and Methods: Twenty subjects underwent one of several protocols: (1) Treatment of 3-mm biopsies within donor site scars with UBM versus untreated controls, (2) Removal of a strip of donor site scar tissue and treatment of the site with UBM, (3) Soaking of occipital hair follicle grafts in a solution of UBM, or (4) Soaking of beard or temple hair follicle grafts. Results: At 6 months, hair was observed in biopsy sites that contained UBM, including donor scar areas that would not normally regrow hair, in contrast to the control biopsy sites. Similar results were observed for the strip excisions. UBM-soaked occipital, beard, and temple hair grafts consistently yielded higher than expected numbers of hair follicles. Conclusions: These cases provide anecdotal support for the hypothesized benefits of UBM regenerative technology in restoration therapy for men and women with androgenetic hair loss.

Abstract
Mesenchymal stem cells (MSCs) are remarkable in stem cell biology. Not only do they have significant tissue regeneration potential, but more recently their paracrine effects (either innate or through genetic augmentation) have become increasingly recognized as useful therapeutic approaches. In particular, clinical roles for MSC therapy in neuroprotection and immune suppression are likely to emerge. These therapeutic effects will be particularly advantageous in work on neurological tissues, because MSC-based molecular therapy could overcome some of the difficulties of long-term drug delivery to tissues, such as the eye, which are relatively inaccessible to systemic delivery (for example due to the blood retina barrier). MSC therapy is, therefore, poised for significant impact in ocular molecular therapeutics, particularly for chronic diseases, such as retinal degeneration, glaucoma, and uveitis. Other molecular and tissue regeneration effects of MSCs are also likely to have impact in the management of ocular surface disease and oculoplastics.
