Objective:
To explore the expression profile of male germ cell-associated genes during the spontaneous differentiation of induced pluripotent stem cells (iPS) and assess the potency of their spontaneous differentiation into male germ cells in vitro.
Methods:
Embryoid body (EB) formation was used to promote the spontaneous differentiation of iPS into male germ cells, and the expressions of germ cell-associated genes were detected by real-time PCR and PCR.
Results:
Real-time PCR and PCR revealed different expression levels of relevant genes at different times of iPS spontaneous differentiation into male germ cells. Each of the 9 genes analyzed exhibited one of the four temporal expression patterns: wavelike increase of Oct4, progressive decrease of Dppa3 and Stra8, wavelike decrease of Dazl, and decrease following initial increase of Tex14, Msy2, Scp1, Scp3 and Akap3.
Conclusion:
Induced pluripotent stem cells express male germ cell-associated genes and male haploid genes during their spontaneous differentiation through EB formation, and have the potency of differentiating into male gametes.
