Microarray data validated by qRT-PCR: the fold change of mRNA expression between HPCs and hepatocytes

Gene	Microarray			qRT-PCR
	HPC	Hep	Fold (M ± SD) a	Fold (M ± SD) b
CD24	P	A	N/A	A/A
CD44	P	A	N/A	A/A
CD99	P	A	N/A	A/A

^a: The fold change in mRNA expression between HPCs and hepatocytes as determined by microarray analysis was calculated from three chips in each group. ^b: The fold change in mRNA expression between HPCs and hepatocytes as measured by real-time RT-PCR; the qRT-PCR results represent five individual samples, and PCR was performed in triplicate for each sample. A, absent; P, present; N/A, not applicable; A/A, absent from both kinds of cells.
