Figure 1. Four types of male germ cells used to construct the lncRNA/mRNA libraries.

(A), Representative photographs of SSC, A, PS, and RS after isolation were shown. (B), Expression levels of the male germ cell specific marker genes transcripts (Gfrα-1 for SSC, c-Kit for A, Scp3 for PS, and Prm2 for RS) were determined by real-time PCR. Data shown are the mean ± SEM of three separate experiments performed in triplicate.
