Ribonuclease protection analysis of cultured keratinocytes and dermal endothelial cells. There was minimal IP-10 mRNA expression in unstimulated keratinocytes, but upon stimulation with TNF-α and IFN-γ, IP-10 mRNA expression was massively increased. Similarly, there was minimal dermal endothelial cell IP-10 mRNA expression, but upon stimulation with TNF-α and IFN-γ, IP-10 mRNA expression was massively increased.
