Table 4. PDS-C up-regulated the mRNA expression levels of GATA-1 and GATA-2 genes by RT-qPCR ($\overline{x}\pm s$, n=3).

Hematopoietic cells	PDS-C (mg/L)	Relative expression level of mRNA
		GATA-1	GATA-2
Erythrocyte	0	1.00±0.31	1.00±0.29
	50	1.41±0.32**	2.41±0.35**
Megakaryocyte	0	1.00±0.30	1.00±0.23
	50	1.62±0.31**	2.14±0.33**

**, P<0.01, vs. untreated control cells. PDS-C, panaxadiol saponins component; RT-qPCR, quantitative reverse transcription polymerase chain reaction.
