MGE 파생 된 CIns로 그룹화 할 수 있습니다 대부분 비중첩 하위 PV 또는 SST, 특정 electrophysiological 및 연결 추세5와 어떤 관계가 식의 그들의 식에 따라. 부전 수, PV 비율에서 특히 그들의 여러 정신병 무질서 및 질병6,7에 연루 되었습니다. 이 방법의 전반적인 목표는 줄기 세포 유래 mitotic 창시자 및 대뇌 피 질의 interneuron 생물학 연구 및 세포 기반 요법에 사용 하기 위해 태양광 또는 SST CIn 운명에 대 한 농축 철새 선구자입니다.
Interneuron 창시자 표현 하는 Nkx2.1 및 mESCs에서 그들의 자손의 파생에 대 한 확장 가능한, 매우 능률적인 방법을 개발 했습니다. Nkx2.1::mCherry:Lhx6::GFP을 사용 하 여 듀얼 기자 mESC 선8, Nkx2.1 창시자 또는 그들의 Lhx6 표현 포스트 mitotic 자손은 FACS를 통해 격리 되 고 이후 다운스트림 응용 프로그램의 수에 사용 될 수 있습니다. 다양 한 신호 경로, 문화, 그리고 성체의 모드를 조작 하 여 우리 붙일 레이블된 interneuron 선구자 다운스트림 응용 프로그램의 호스트에 대 한 적합의 수백만 얻을 수 있습니다.

differentiation of mouse embryonic stem cells into cortical interneuron precursors

GABAergic 대뇌 피 질의 수는 흥분 성의 피라미드 뉴런의 출력 조절 피라미드 뉴런 앙상블의 출력을 동기화에 중요 한 역할을 하는 셀의 이종 인구. 정신병 무질서, 정신 분열 증, 자폐증, 간 질 등의 다양 한에서 적자 interneuron 함수에 연루 되었습니다. 배아 줄기 세포 로부터 대뇌 피 질의 수의 뿐만 아니라 그들의 개발 및 기능 연구에 대 한 허용 하지만 대뇌 피 질의 interneuron 관련 장애의 병 인을 기본 분자 메커니즘에 대 한 통찰력을 제공 합니다. 수는 또한, 마이그레이션, 생존과 호스트 대뇌 피 질의 회로 후 이식, 그들 세포 기반 요법에 사용 하기 위해 이상적인 후보자를 만들기에 통합 놀라운 능력을가지고. 여기, 우리 Nkx2.1 표현 interneuron 창시자와 마우스 배아 줄기 세포 (mESCs)에서 그들의 자손의 파생에 대 한 확장성, 높은 효율, 수정 embryoid 몸 단층 방법 제시. Nkx2.1::mCherry:Lhx6::GFP 듀얼 기자 mESC 라인을 사용 하 여, Nkx2.1 창시자 또는 그들의 Lhx6 표현 포스트 mitotic 자손 수 형광 활성화 셀 정렬 (FACS)를 통해 격리 되며 이후 다운스트림 응용 프로그램의 숫자에 사용. 우리는 또한 방법을 풍부 하 게 parvalbumin (태양광 발전) 또는 somatostatin (SST) interneuron 하위 그룹을 도움이 될 수 있습니다 운명 결정의 측면을 공부 하거나 사용 하기 위해 하위 그룹 농축 interneuron에서 도움이 될 것 이라고 하는 치료 응용 프로그램에 제공 이식입니다.

이 문서에 설명 된 프로토콜 우리의 게시 프로토콜15,,1617 의 수정된 된 버전 이며, 우리의 Nkx2.1::mCherry:Lhx6::GFP 듀얼-기자 mESC 선으로 사용 하기 위해 최적화 되었습니다. DD0-5, 다시 도금 DD8에서 결합 XAV 939 Wnt 억제제를 추가 하 여 우리는 어떤 점에서 모든 DAPI + 핵 문화에서의 50% 이상을 또한 Nkx2.1 표현 (<s...
