One of the most effective and safe therapeutic methods for treating vitiligo, mixed autologous keratinocytes (KCs) and melanocytes (MCs) cultures have been used for autologous cell transplantation. However, the present transplantation method is faced with a problem that may require a large amount of skin tissue and keratinocytes have limited culture potency. We have found previously that human adipose derived stromal cells (hASCs) from aspirated fat tissue could be used in place of KCs and sufficient amounts of hASCs for transplantation could be obtained by small amount of aspirated fat tissue. The present investigation was determined the effect of ASCs on ex vivo expansion MCs for transplantation. In addition, we examined for a preservation conditions of MCs which have reported low recovery rates and a slowdown in growth after cryopreservation. Various conditions including ASCs ratio, incubation period, and additive materials for MCs cultivation was determined to improve the expansion ability of MCs. The growth rate of MCs colony was elevated 6.85 folds compared the previous conditions. These MCs showed a specific expression of immature melanocyte protein, Trp-2, but did not express the mature melanocyte proteins and markers (c-kit, CD133, and etc.) of mesenchymal stem cells that represents in ASCs feeder. Results in cryopreservation experiments were determined a preservation medium for MCs showing an increased recovery rates after thawing. The characteristics of MCs after cryopreservation using a designed medium were indicated consistent morphology and immunophenotype. In conclusion, ASCs as a feeder could be used in place of keratinocytes for ex vivo expansion of MCs. For clinical trial for vitiligo patients, efficiency experiments in preclinical state should be followed.
