이 프로토콜 유럽 장 어 성숙, 처리 및 정자 cryopreservation에 대 한 완전 한 프로세스를 설명합니다. 여기에 설명 된 농업 조건 빠른 성숙 및이 종 6,,725에 높은-품질의 높은 볼륨의 생산을 위한 최적의 있습니다. 이 cryopreservation 프로토콜 및 해빙 후 수정에 대 한 그것의 잠재적인 사용의 성공 신선한 정자 26의 품...

지난 25 년 동안 유럽 뱀장어 (앵귈라 앵귈라) 유럽 해 안에 도착의 수는 꾸준히 90 1,2,3감소. 오염, 감염, overfishing, 서식 지 파괴 등이 급격 한 하락을 설명 하는 몇 가지 요인이 있다. 이 모든 중요 한 멸종 위기 4자연 보존 (IUCN) 목록은 국제 연합에 유럽 장 어의 포함에 지도 하는이 종에 깊은 영향을 했다. 따라서, 기술 및 포로에 복제에 대 한 프로토콜의 개발은 필요 합니다.
포로에서 유럽 장 어의 성숙 호르몬 치료 5,,67 에 의해 이루어집니다 하지만 남녀 모두에서 gametes의 생산 8동기화 할 어렵습니다. 새로운 안 드로 겐 임 플 란 트의 개발 oogenesis 뱀장어 9,에 있는 가속을 보이고 있다 하더라도10, 여성에서 마지막 성숙의 타이밍은 여전히 매우 변수 하 고 11를 제어 하기 어려운. 따라서, 기술의 정자 12,,1314 및 cryopreservation 단기 저장 복제 관리, 생식 체 동기화 불필요 한 8를 만들기 위해 필요 하다.
유럽 장 어 정자의 cryopreservation 2003 15,16이후 개발 되었습니다. 몇몇 연구원은 성공적인 프로토콜 cryoprotectants 16,17,18,,1920디 메 틸 sulfoxide (DMSO) 또는 메탄올을 사용 하 여 설계 되었습니다. 두 프로토콜 성공적으로 사용 되었습니다, 하지만 해 동된 정자 DMSO와 cryopreserved의 얻은 세포 생존 능력에 메탄올 20,21보다 낮은 것입니다. 또한, 장 정자 DMSO와 접촉을 활성화 하 고 더 지루한 정자 조작 19필요 하, 그러므로 메탄올 DMSO 보다 유럽 장 어 정자에 대 한 더 적합 한 cryoprotectant 이다.
여기, 아래 최적의 처리 및 유럽 장 어의 호르몬 치료에 대 한 프로토콜을 설명 합니다. 이것 이외에,이 종에서 정자 품질 평가 대 한 프로토콜은 cryoprotectant로 메탄올을 사용 하 여 최고의 유럽 장 어 정자 cryopreservation 프로토콜도 설명 됩니다.

handling and treatment of male european eels (anguilla anguilla) for hormonal maturation and sperm cryopreservation

지난 년 동안 여러 연구 그룹 개발 및 유럽 장 어 처리 및 성숙에 대 한 새로운 프로토콜의 개선에 노력 하고있다. 로 서 아직, 인간 융 생식 샘 자극 호르몬 (hCG)의 주간 주사 치료, 몇 주 동안 높은-품질의 높은 볼륨 생산의 단지 5-6 주 후 남성 maturate를 입증 해야 합니다. 또한, 정자 cryopreservation 프로토콜 다른 extender를 사용 하 여, cryoprotectants 및 냉각 시간을 녹고 있다 이전 설명 유럽 장 어에 대 한. 여기, 우리가 보여줍니다 수정 또는 cryopreservation, Tanaka´s 익스텐더 솔루션 직접 사용 될 수 있다 솔루션 및 희석의 다른 종류의 사용을 불필요 한 만들기. 또한, 메탄올의 사용은 cryoprotectant로 만드는이 프로토콜 사용 하기 쉬운 메탄올은 낮은 독성과 정자를 활성화 하지 않습니다. 정자는 cryoprotectant 추가 직후 cryopreserved 필요 하지 않습니다 그리고 그것은 오래 되 고 해 동 후 사용할 수 있습니다. 또한, 정자 운동 성은 비록 그것이 신선한 정자 보다 낮은 녹고 후 여전히 높다입니다. 이 작품의 목표 처리, 성숙 및 정자 cryopreservation 유럽 장 어에 대 한 가장 사용할 수 있는 프로토콜을 표시 하는 것입니다.

70% 이상, 정자 운동 성 가진 18 뱀장어에서 정자는이 연구에 대 한 선정 됐다. 결과 신선한 정자 (표 1 및 그림 2)에서 그에 비해 녹고 후 모든 품질 매개 변수에서 감소를 보였다. 운동 성 결과 (± S.E.M., 의미 n = 18) 총 운동 성 및 진보적인 운동 후 해 동 정자 샘플에서 발견 보다 신선한 정자에 더 높은 총 운동 성 및 진보적인 운동 성을 보였...
