Expression level of KitL mRNA and KL-1/KL-2 ratio in skin tissues of B6-mi/mi and WB-mi/mimice.

(A) Semiquantitative RT-PCR to compare the expression level of KitL mRNA. RNAs extracted from skin tissues of B6-mi/mi and WB-mi/mi mice were subjected to RT-PCR. (B) RT-PCR Southern analysis to examine KL-1/KL-2 ratio. (C) KL-1/KL-2 ratio. The intensity of the bands for KL-1 and KL-2 mRNAs was quantified by densitometry, and the ratio was calculated. The bars represent the means ± SEs of 3 independent experiments.
