Scale bar, 20 μm. m, Purities of SG (82.60 %), PS (82.69 %), RS (87.76 %), ES (81.9 %), IC (92.63 %) and SC (96.35 %) cells. n = 3. n, Quantification of Rpl39 and Rpl39l mRNA levels in testicular cells by qPCR. n = 3. o, Absolute protein quantification of RPL10, RPL10L, and RPL22, RPL22L1 in testicular cells by PRM. n = 3. For g, h, k, m, n and o, data are mean ± s.e.m. n values represent the number of samples.
