    Santa Cruz Biotechnology protamine 1 prm1
    Nonhuman primate embryonic stem cell (nhpESC) histone 2B-green fluorescent protein (H2B-GFP) cells differentiated in spermatogonial stem cell (SSC) conditions yield haploid, round spermatid-like cells. ( A ) Representative cell cycle flow cytometry profile data from one of five separate differentiations (n = 5) ( left image ) of nhpESC H2B-GFP cells differentiated in SSC conditions for 10 days. The dark green peak on the left-hand side of the graph represents the 1N peak ( asterisk ). ( B ) Fluorescence in situ hybridization (FISH) confirms haploidy. Representative FISH images from five different (n = 5) nhpESC H2B-GFP cells differentiated for 10 days in SSC conditions. The FISH Probe for chromosome 1 ( green ) shows a diploid cell ( left image ) with two chromosome 1s ( arrow indicating two green dots ), and sorted haploid cells ( right image ) show one chromosome 1 (arrow indicating one green dot ). Bar = 5 μ m. ( C ) Following our 10-day differentiation, haploid cells were sorted by fluorescence-activated cell sorting and immunostained with antibodies against postmeiotic spermatid markers ( red , third column ) acrosin ( top row ), <t>Protamine</t> <t>1</t> <t>(PRM1;</t> middle row ), and Transition Protein 1 (TNP1; bottom row ). H2B-GFP ( green , second column ); Hoechst stain ( blue , first column ) for deoxyribonucleic acid. Merge of fluorescence images ( fourth column ). Bar = 10 μ m. Data shown are representative of five separate differentiations (n = 5). ( D ) Representative images of round spermatids from a rhesus testis cell biopsy ( left ) and an in vitro-derived round spermatid-like cell ( right ) stained with 4′,6-diamidino-2-phenylindole ( blue ), Protamine 1 ( red ), and acetylated tubulin ( green ). Bar = 5 μ m.
