In 20 patients who have stable vitiligo with the duration of stability more than 3 months, non cultured epidermal cell suspension will be done. Patients will be divided into 2 subgroups of 10 patients each of stability duration of 3-6 months and more than 1 year respectively and non cultured epidermal cell suspension will be done.

In 20 patients who have stable vitiligo with the duration of stability more than 3 months, combination of non cultured epidermal cell suspension and non cultured dermal cell suspension will be done. Patients will be divided into 2 subgroups of 10 patients each of stability duration of 3-6 months and more than 1 year respectively and combination of non cultured epidermal cell suspension and non cultured dermal cell suspension will be done.

Vitiligo

Non cultured epidermal cell suspension Split thickness skin specimen will be transferred under aseptic conditions to a container with normal salineand transferred to laboratory. There, the skin graft will be transferred to Trypsin-EDTA solution (0.25% trypsin and 0.02% EDTA) in a Petri dish and incubated overnight at 4°C in 5% CO2 to separate the epidermis from the dermis.Afterwards, the Trypsin-EDTA solution will be removed and PBS will be added and pipetted well so as to separate the cells from the tissue.The suspension will be centrifuged at 1000 rpm for 5 minutes.The supernatant will then be discarded and Phosphate buffer saline is added to make suspension of non-cultured epidermal cells.

Non cultured epidermal cell suspension

Non-cultured Dermal Cell Suspension Skin punch will be collected in phosphate buffer saline (PBS) with antibiotics (penicillin and streptomycin). The epidermis will be cut off from dermis carefully using a surgical blade (Epidermal part will be used for the epidermal cell suspension). Dermis will be then cut into small pieces and incubated in collagenase (1mg/ml) overnight at room temperature. Next day content will be diluted with PBS and centrifuged at 1000rpm for 5 minutes. Pellet will be washed three times with PBS to remove collagenase activity. Phosphate buffer saline is added to make suspension of non-cultured dermal cells and will be used for the autologous transplantation.

Repigmentation will be assessed as follows -
≤25% Minimal repigmentation 26-50% Mild repigmentation 51-75% Moderate repigmentation 76-90% Marked repigmentation >90% Excellent repigmentation
