    Rattus norvegicus Spermatogenesis Colony-Forming Assays

    Knowledge gaps persist on signaling pathways and metabolic states in germ cells sufficient to support spermatogenesis independent of a somatic environment. Consequently, methods to culture mammalian stem cells...

    Long Evans rat spermatogonial lines are effective germline vectors for transgenic rat production

    Long Evans rat strains are applied as research models in a broad spectrum of biomedical fields (>15,800 citations, NCBI PubMed). Here, we report an approach to genetically modify the Long Evans rat germline in...

    GSG1L suppresses AMPA receptor-mediated synaptic transmission and uniquely modulates AMPA receptor kinetics in hippocampal neurons

    Regulation of AMPA receptor (AMPAR)-mediated synaptic transmission is a key mechanism for synaptic plasticity. In the brain, AMPARs assemble with a number of auxiliary subunits, including TARPs, CNIHs and CKAM...

    Slee** Beauty transposon mutagenesis in rat spermatogonial stem cells

    We describe an experimental approach for generating mutant alleles in rat spermatogonial stem cells (SSCs) using Slee** Beauty (SB) transposon–mediated insertional mutagenesis. The protocol is based on mobiliza...

    Rat Spermatogonial Stem Cell-Mediated Gene Transfer

    More than 20 years have passed since the advent of genetic manipulation of the mouse germline using cultures of pluripotent embryonic stem cells. Still, despite remarkable successes in the mouse, the applicati...

    Enter the rat

    Advances in stem-cell technology have broken the barrier to gene targeting in mammals other than mice. A wide array of research opportunities now opens up, especially in studies involving the laboratory rat.

    Generating knockout rats by transposon mutagenesis in spermatogonial stem cells

    Cultured rat spermatogonia, genetically modified via a transposon-based gene trap, are inserted into the testes of sterile rats and give rise to mutant progeny with many different genotypes.

    Isolating Highly Pure Rat Spermatogonial Stem Cells in Culture

    Methods are detailed for isolating highly pure populations of spermatogonial stem cells from primary cultures of testis cells prepared from 22- to 24-day-old rats. The procedure is based on the principle that ...
