Green fluorescent protein (GFP)-labeled PGC were cooled rapidly using liquid nitrogen after exposure to a pretreatment solution containing 1.5 M cryoprotectant (ethylene glycol or dimethyl sulfoxide, 30 or 50 min) and a vitrification solution containing 3 M cryoprotectant and 0.5 M sucrose (5, 10, 20, or 30 min). Embryonic cells that were pretreated for 30 min and vitrified for 20 min with ethylene glycol had the greatest rate of survival of embryonic cells (68.6%; P < 0.01), an optimal highest percentage of viable PGC (73.8% to 74.9%; P < 0.05), and no evidence of ice formation after thawing. The vitrified/ thawed PGC were transplanted into blastula-stage embryos from goldfish (Carassius auratus). The PGC maintained their motility and moved to the gonadal ridge of the host embryo. Thus, the combination of vitrification and transplantation to produce germ-line chimeras is a powerful tool for the artificial production of next-generation offspring.American Society of Animal ScienceJournal Articleapplication/pdfhttp://hdl.handle.net/2115/51756https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/51756/1/JAS90-2_495-500.pdf0021-8812Journal of Animal Science9024955002012-02enginfo:pmid/21926320info:doi/10.2527/jas.2011-4329author
