%X Autologous cultured pure melanocyte transplantation (CMT) can be utilized to treat stable vitiligo cases, but clinical data are insufficient to improve its efficacy. To evaluate the influence of various factors on the therapeutic effect of CMT, this single-center retrospective study enrolled stable vitiligo patients who underwent CMT between 2009 and 2020. Univariate and multivariable analysis were used to determine the factors affecting the outcome of repigmentation. The study included 491 patients with long-term follow-up data (6-120 months). It was found that 69.7% of patients achieved an excellent re-color effect and 18.4% achieved a good re-color effect. There were statistically significant differences in pigmentation between patients with stable disease course, vitiligo type, and lesion site. Overall, a significant positive correlation between the target area treatment ratio of varied lesions and the percentage of repigmentation was found. CMT is effective and well tolerated in the treatment of stable vitiligo. Various factors, especially the target area treatment ratio of varied lesions, should be carefully assessed before using CMT. As the target area treatment ratio of varied lesions could further improve the post-operative repigmentation other than type of vitiligo. This clinic trial was approved by Hangzhou Third People's Hospital (number 2023KA015, national clinical record number MR-33-23-034502).
