Table 3. Tyrosinase mRNA (Ty-mRNA) detection results via reverse transcriptase polymerase chain reaction (RT-PCR), from receptor skin biopsies before and after grafting (among 12 receptor areas).

	Positive Ty-mRNA	Negative Ty-mRNA
Before grafting	1	11
After grafting	12 (100.0%)	None

Conversion percentage = 100.0%.
