This characterization can support pathophysiological models and treatment strategies.This study aimed to explore the morphology, growth rate and gene expression profile of fibroblasts from facial melasma, compared to adjacent photoexposed skin.MethodsThis project was approved by the Research Ethics Council (Unesp, Botucatu-SP, number 0461-11). and all participants consented to participate.Ten adult women with facial melasma underwent biopsy (2-mm punch, using a sterile technique) of the melasma skin on the malar region and from the adjacent, clinically normal, photoexposed skin (<2 cm of distance), laterally. The participants were untreated for the dermatosis for at least 30 days, except for the use of sunscreen.The skin fragments were sectioned and placed in fibroblast culture, maintained in medium 106 (Gibco™) containing growth factors (LSGS Kit, Gibco™). The fibroblasts were seeded (in triplicate) at a density of 5 × 103 in a 12-well cell culture plate.Cultured fibroblasts, from healthy and damaged skin, from five participants, were seeded at a density of 1 × 104 in a 6-well cell culture plate, and the number of cells per cm2 was evaluated after two, five and eight days, based on the evaluation of 30 fields, and compared (between topographies) by a generalized linear mixed-effects model. Sample normality was evaluated by the Shapiro-Wilk test.Subsequently, cell senescence was evaluated using senescence β-galactosidase (SA-β-gal) staining kit (Cell Signaling Technology®), following the manufacturer's instructions. After 24 hours of cell plating, the culture medium was removed, followed by washing with PBS and the addition of fixation solution for 15 minutes at room temperature. Then, it was washed with PBS twice, followed by overnight incubation with β-galactosidase solution (Cell Signaling Technology®) at 37 °C. After the solution was removed, 70% glycerin was added.A total of 300 cells were counted per sample. The morphology of the cultured fibroblasts and the percentage of cells labeled with cytoplasmic SA-β-gal were compared between the topographies (melasma and adjacent healthy skin).Fibroblasts from the primary cell culture of the other five participants were submitted to a real-time PCR array (96-well plate, Custom RT2 Profiler PCR Arrays, Qiagen) to assess the expression of 39 genes associated with growth factors and tissue repair, WNT pathway activation, neocollagenesis, metalloproteinase synthesis, estrogen receptors, and antioxidant mechanisms (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>).

These morphological and metabolic changes support a senescent phenotype in melasma skin fibroblasts.Senescence is a central factor in the mechanisms of aging, and the Senescence-Associated Secretory Phenotype (SASP) is known to be the main trigger of age-related phenotypes, such as wrinkles and pigmentation.<a class="elsevierStyleCrossRef" href="#bib0080">16</a> It should be noted that there is evidence of phenotypic differences related to ethnicity and susceptibility to fibroblast senescence.<a class="elsevierStyleCrossRef" href="#bib0085">17</a>Senescent fibroblasts secrete inflammatory cytokines and stem cell factors, which promote collagen degradation through MMP activation and have reduced mitotic potential.

Damage to the upper dermis and the basement membrane zone facilitates the transit of melanogenic factors to the basement layer. In the present study, despite a marginal implication, MMP9 showed a high fold change (>2), which, in association with the lower expression of TIMP1 and 4, suggests participation of melasma skin fibroblasts in the deficient repair of the upper dermis and angiogenesis.The role of sex hormones in cutaneous estrogen receptor β expression in melasma is well established.<a class="elsevierStyleCrossRef" href="#bib0095">19</a> Overall, ESR2 is expressed during the repair process.<a class="elsevierStyleCrossRef" href="#bib0100">20</a> The upper dermis and basement membrane are heavily damaged in melasma skin, compared to adjacent healthy, photoexposed skin and photoprotected skin.<a class="elsevierStyleCrossRefs" href="#bib0005">1,14</a> Moreover, estrogen, α-MSH, and HGF stimulate melanogenesis by directly binding to the melanocyte receptor and are also released during the wound healing process.<a class="elsevierStyleCrossRefs" href="#bib0105">21,22</a> These findings indicate that the chromic and unsuccessful upper dermis repair process can induce melanogenesis in melasma.Some genes related to the Wnt/β-catenin pathway showed different behavior in fibroblasts from the skin with melasma, in relation to photoexposed adjacent skin; the DKK3 inhibitory factor was down-regulated, while WNT3A was overexpressed.

However, the results were consistent and allowed the authors to explore, in a preliminary way, the hypothesis about the role of fibroblasts in the pathogenesis of melasma, proposing new investigations related to the pathogenesis and therapeutic strategies of melasma. The sample of patients submitted to the senescence and proliferation assay was different from the one submitted to the gene expression comparison, although the results were parallel. Finally, the investigation of fibroblasts from controls without melasma, matched by age, photoexposure pattern, photoaging, and phototype, could also elucidate the particular susceptibility of fibroblasts from individuals with melasma to senescence.Further studies should investigate the regulatory factors of these pathways and the cytokine network between keratinocytes, melanocytes, nerves, endothelium, and fibroblasts in melasma, preferably through studies with tissue cultures, for genomic, proteomic, and functional experiments.ConclusionsFibroblasts from the skin with melasma showed a lower growth rate, less fusiform morphology, and greater accumulation of SA-β-gal than those from adjacent healthy photoexposed skin. Furthermore, their gene expression profile comprised pro-inflammatory, pro-melanogenic, and tissue repair deficit-related factors, which can induce damage to the upper dermis and support the focal pigmentary phenotype in melasma.Financial supportFAPESP – number 2012/09233-5, 2012/05004-1; CNPq – number 401309/2016-9.Authors' contributionsAna Cláudia Cavalcante Espósito: Design and planning of the study; collection, analysis, and interpretation of data; drafting and editing of the manuscript; Critical review of the literature; Approval of the final version of the manuscript.Gabrielli Brianezi: Design and planning of the study; collection, analysis, and interpretation of data; approval of the final version of the manuscript.Luciane Donida Bartoli Miot: Design and planning of the study; collection, analysis, and interpretation of data; effective participation in research orientation; approval of the final version of the manuscript.Hélio Amante Miot: Design and planning of the study; collection, analysis, and interpretation of data; statistical analysis; drafting and editing of the manuscript; critical review of the literature; critical review of the manuscript; approval of the final version of the manuscript.Conflicts of interestNone declared."

ObjectiveTo explore the morphology, growth rate, and gene expression profile of fibroblasts from the skin with melasma in comparison to fibroblasts from the adjacent healthy skin. MethodsTen women with facial melasma were biopsied (lesion and adjacent healthy skin), and the fragments were processed for fibroblast culture. Samples from five participants were seeded to evaluate growth (days 2, 5 and 8) and senescence (SA-β-gal) curves. The samples from the other participants were submitted to real-time PCR to comparatively evaluation of the expression of 39 genes. ResultsCultured fibroblasts from melasma skin were morphologically less fusiform in appearance and on average a 34% (95% CI 4%‒63%) greater proportion of cells labeled with SA-β-gal than the fibroblasts from the adjacent skin. The cell growth rate was lower for the melasma samples after eight days (p < 0.01). TheWNT3A, EDN3, ESR2, PTG2, MMP1, and SOD2 genes were up-regulated, whereas the COL4A1, CSF2, DKK3, COL7A1, TIMP4, CCL2, and CDH11 genes were down-regulated in melasma skin fibroblasts when compared to the ones from adjacent healthy skin. Study limitationsSmall sample size; absence of functional tests. ConclusionsFibroblasts from the skin with melasma showed a lower growth rate, less fusiform morphology and greater accumulation of SA-β-gal than those from adjacent photo exposed skin. Moreover, their gene expression profile comprised factors that may contribute to upper dermis damage and sustained melanogenesis."
