Hair-forming potency of GFP-positive and GFP-negative cells by an in vivo cell-grafting assay

Dermal component	Epidermal component	Success rate
Sorted GFP + cells	Keratinocytes	7 /7 (4) 100%
Sorted GFP − cells	Keratinocytes	0/5 (3) 0%
Sorted GFP + cells	None	0/3 (2) 0%
Unsorted dermal cells	Keratinocytes	3/3 (2) 100%
Re-sorted GFP + cultured cells	Keratinocytes	3/3 (2) 100%
Re-sorted GFP − cultured cells	Keratinocytes	0/4 (2) 0%

Success rate is number of haired mice/number of mice grafted; numbers in parentheses are the number of experiments performed separately.
