摘要: 为了建立针对鹅原始生殖细胞(primordial germ cells,PGCs)的分离纯化与冷冻保存方法,对血液Ficoll密度梯度离心法、血液ACK裂解法、生殖腺胰酶-EDTA消化法与生殖腺消化结合体外短时间培养法4种PGCs分离方法以及STEM-CELLBANKER、CELLBANKER 2与10%DMSO加90%血清等3种冻存液进行了比较研究。通过形态学观察、糖原染色与PGCs特异免疫荧光染色鉴定PGCs,同时利用台盼蓝染色检测PGCs活力等方法对其分离和保存效果进行评价。结果表明,从鹅胚血液与生殖腺中均已经成功分离到鹅PGCs;生殖腺消化结合体外短期培养法与传统的血液分离法相比,获得的鹅PGCs数量、纯度与活力最高,每枚胚胎获得的鹅PGCs数量达到115个、细胞纯度达80.8%、细胞活率达88.3%;而商业化的干细胞冷冻保护液STEM-CELLBANKER同一般的体细胞冻存液相比更适合鹅PGCs的冷冻保存,冷冻解冻后的细胞存活率达90%左右。试验可以得出结论:生殖腺消化结合体外短期培养法成功分离到数量与纯度都可观的鹅PGCs,STEM-CELLBANKER冻存液能够用于鹅PGCs的长期冷冻保存。

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
