Croton oil initiates skin disease in female mice

	Spontaneous disease	0.8% croton oil	Fisher's exact test
Male	9/47 (19%)	2 /11 (18%)	P = 1.0
Female	9/43 (21%)	5/7 (71%)	P = 0.014
Total	18/90 (20%)	7/18 (39%)	P = 0.122

The number of either unmanipulated mice or mice treated at age 10 days with 0.8% croton oil that developed clinically apparent cutaneous GVHD. All mice tallied here were from the 3339 line of 2-2-3/K14-A_β
