Abstract
Skin is composed of major layers, namely a superficial epidermis and a deeper dermis. The color of skin is influenced by a number of pigments, including melanin, which is produced by cells called melanocytes. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal. A number of more noticeable disorders, namely albinism and vitiligo, affect the appearance of the skin and its accessory organs. Vitiligo is associated with significant psycho-social morbidity and a major effect on quality of life. Topical steroids, calcineurin inhibitors, phototherapy and surgery are the most common treatments for melanoma. However, there are many patients who do not respond to any of these modalities. The transplantation of cultured or non-cultured melanocyte is the most important treatment for hypopigmentory disorders. This study aims at reviewing the history of melanocyte cultivation, and evaluating the effectiveness of transplantation of cultured cells. For this purpose, the authors examined the initial process of isolation, characterization, and transplantation of epidermal cells. This review, thus, summarizes the current understanding of the cutaneous pigmentary system from the start of synthesis in the pigment cells, along with the response of repigmentation. During the production of melanin, melanosomes are transferred to neighboring keratinocyte in order to form perinuclear melanin caps. The objective of this review is to analyze the melanocytes transplantation in the last century to date, and explore the methods epidermal cells can increase pigmentation in hypo-pigmented areas in skin disorders. Moreover, the focus is on the story of the melanocyte back to 1950s. In addition, prior systemic therapy was associated with a significant increase, based on combined additional therapy, achieving desired results and improved outcomes. Despite the short study of a long way of melanocyte assessment and following up patient treatment, results of the all reports confirmed the efficacy of the method used in the treatment of stable vitiligo patients, who did not respond to the common algorithms of non-invasive treatments.

Abstract
The skin, as the largest organ, covers the entire outer part of the body, and since this organ is directly exposed to microbial, thermal, mechanical and chemical damage, it may be destroyed by factors such as acute trauma, chronic wounds or even surgical interventions. Cell therapy is one of the most important procedures to treat skin lesions. Fibroblasts are cells that are responsible for the synthesis of collagen, elastin, and the organization of extracellular matrix (ECM) components and have many vital functions in wound healing processes. Today, cultured autologous fibroblasts are used to treat wrinkles, scars, wounds and subcutaneous atrophy. The results of many studies have shown that fibroblasts can be effective and beneficial in the treatment of skin lesions. On the other hand, skin substitutes are used as a regenerative model to improve and regenerate the skin. The use of these alternatives, restorative medicine and therapeutic cells such as fibroblasts has tremendous potential in the treatment of skin diseases and can be a new window for the treatment of diseases with no definitive treatment.

Differential Expression of Insulin-Like Growth Factor 1 and Wnt Family Member 4 Correlates With Functional Heterogeneity of Human Dermal Fibroblasts. Front Cell Dev Biol 2021; 9:628039. [PMID: 33889572 PMCID: PMC8056032 DOI: 10.3389/fcell.2021.628039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Accepted: 03/09/2021] [Indexed: 11/22/2022] Open
Abstract
Although human dermis contains distinct fibroblast subpopulations, the functional heterogeneity of fibroblast lines from different donors is under-appreciated. We identified one commercially sourced fibroblast line (c64a) that failed to express α-smooth muscle actin (α-SMA), a marker linked to fibroblast contractility, even when treated with transforming growth factor-β1 (TGF-β1). Gene expression profiling identified insulin-like growth factor 1 (IGF1) as being expressed more highly, and Asporin (ASPN) and Wnt family member 4 (WNT4) expressed at lower levels, in c64a fibroblasts compared to three fibroblast lines that had been generated in-house, independent of TGF-β1 treatment. TGF-β1 increased expression of C-X-C motif chemokine ligand 1 (CXCL1) in c64a cells to a greater extent than in the other lines. The c64a gene expression profile did not correspond to any dermal fibroblast subpopulation identified by single-cell RNAseq of freshly isolated human skin cells. In skin reconstitution assays, c64a fibroblasts did not support epidermal stratification as effectively as other lines tested. In fibroblast lines generated in-house, shRNA-mediated knockdown of IGF1 increased α-SMA expression without affecting epidermal stratification. Conversely, WNT4 knockdown had no consistent effect on α-SMA expression, but increased the ability of fibroblasts to support epidermal stratification. Thus, by comparing the properties of different lines of cultured dermal fibroblasts, we have identified IGF1 and WNT4 as candidate mediators of two distinct dermal functions: myofibroblast formation and epidermal maintenance.
