Project description:Single Cell Microarray <br>E10.5 genital ridges (TM at E7.5) incubated in 0.5mM EDTA/ PBS for 20 minutes at 37ï¾°C were transferred to 2% BSA/ PBS. PGCs were collected from the genital ridges pierced with fine glass needles. Released PGCs were identified by their morphological characteristics and transferred into lysis buffer with a mouth pipette. PGCs were genotyped with the remaining genital ridges. The amplified cDNA library of each PGC was classified by qPCR-based expression analyses of Nanog, Oct4, and Stella/Dppa3 (Kurimoto et al., 2007). cDNAs were labeled by in vitro transcription (Affymetrix). The cRNAs were hybridized with the GeneChip Mouse Genome 430 2.0 Array (Affymetrix). Data were analyzed using the Microsoft Excel and MeV (multiple experimental viewer) software. <br>
