  • Stem cell pluripotency genes play a key role in the early development of animals. According to known species’ stem cell pluripotency genes,four genes（ Oct4,Nanog,Sox2 and c-Myc） were cloned by using the homologue-sequence method from the earthworm Eisenia foetida. The expression of these four genes was detected by the real-time fluorescence quantitative PCR in the earthworm E. foetida at the early development stage. The expression of the four genes was escalated gradually from day 0 to 21,the highest at 21 d at the cocoon hatching stage,but declined at day 28. Three genes Oct4,Nanog and c-Myc were detected to have higher expression at the larval stage than at the cocoon hatching stage. This suggested that the four genes had similar expression pattern and might have a synergistic effect during the early development of Eisenia fetida.

Abstract: Stem cell pluripotency genes play a key role in the early development of animals. According to known species’ stem cell pluripotency genes,four genes（ Oct4,Nanog,Sox2 and c-Myc） were cloned by using the homologue-sequence method from the earthworm Eisenia foetida. The expression of these four genes was detected by the real-time fluorescence quantitative PCR in the earthworm E. foetida at the early development stage. The expression of the four genes was escalated gradually from day 0 to 21,the highest at 21 d at the cocoon hatching stage,but declined at day 28. Three genes Oct4,Nanog and c-Myc were detected to have higher expression at the larval stage than at the cocoon hatching stage. This suggested that the four genes had similar expression pattern and might have a synergistic effect during the early development of Eisenia fetida.
