Abstract
To discuss the advantages and limitations of hair follicle-derived cell transplantation (FCT) in vitiligo, compared to the epidermal cell transplantation (ECT), and the knowledge gap which is required to be bridged. The papers relevant to the purpose was reviewed. Surgical approaches for treating vitiligo are based on the idea of replenishing lost melanocytes. Skin and hair follicles as the main sources of melanocytes have been applied for this purpose transferring the whole tissue or tissue-derived cell suspension to the vitiligo lesions. Considering the differences between hair follicle and epidermis in terms of the constituting cell populations, phenotype and function of melanocytes, and micro-environmental factors, different response of vitiligo patients to treatment with FCT or ECT would be expected theoretically. However, there is currently a lack of evidence on such a difference. However, ECT appears to be a more feasible, less time-consuming, and more comfortable treatment for both physicians and patients. Although the current evidence has not shown a significant difference between ECT and FCT in terms of efficacy, ECT appears to be more feasible specifically in the treatment of large lesions. However, further randomized controlled clinical trials with larger sample sizes and longer follow-up durations are required to be conducted to draw a definite conclusion on comparing FCT with ECT in terms of the safety, efficacy, durability of the therapeutic effects, and indications in vitiligo patients.

Abstract
Vitiligo is an acquired skin disorder characterized by the destruction of melanocytes resulting in achromic macules and patches involving the affected skin. Multiple methods of treatments have emerged to manage vitiligo, including medical and surgical techniques. Among the surgical techniques described in the management of vitiligo are minipunch grafting, split-thickness skin grafting, hair follicle transplantation, suction blister grafting, and cultured and non-cultured autologous melanocyte transplantation. However, prior to grafting optimal recipient-site preparation is needed for graft survival and successful repigmentation outcomes. Similarly, post-operative care of the recipient site is vital to yielding a viable graft irrespective of the transplantation technique employed. This article reviews the multiple methods employed to prepare the recipient site in vitiligo surgeries and the post-surgical conditions which optimize graft viability. A pubmed search was conducted utilizing the key words listed below.
