Abstract: In order to establish the isolation and cryopreservation method for goose primordial germ cells (PGCs), four kinds of PGCs separation methods,which were blood Ficoll density gradient centrifugation, blood ACK lysis method, gonads trypsin-EDTA digestion method and gonads digestion combined with short-term culture method, were compared in this experiment. And three kinds of cryoprotectors that were STEM-CELLBANKER, CELLBANKER 2 and 10% DMSO plus 90% serum were compared to evaluate the cryopreservation efficiency of goose PGCs. Morphological observation, PAS and PGCs specific immunofluorescence staining were used to verify PGCs, and trypan blue staining was used to detect the vitality of PGCs. The results showed that goose PGCs were successfully isolated from the blood and gonad of goose embryo. Gonads digestion combined with short-term culture method got the highest goose PGCs quantity, purity and vitality, reached 115 cells per embryo, 80.8% and 88.3% respectively, compared with the traditional blood separation method. Commercial stem-cell cryoprotector STEM-CELLBANKER was more suitable for cryopreservation of goose PGCs than the normal cell cryoprotectants, and the cell survival rate was about 90% after thawing. Gonads digestion combined with short-term culture method could get sufficient quantity and purity of goose PGCs. STEM-CELLBANKER could be used for the long-term cryopreservation of goose PGCs.

Key words: goose, primordial germ cells, gonads digestion combined with short-term culture, cryopreservation
