organotypic slice cultures to study oligodendrocyte dynamics and myelination

NG2 발현 세포 (polydendrocytes, 희소 돌기 아교 세포 전구 세포)는 중추 신경계에서 주요한 넷째 신경교 세​​포 집단이다. 배아 및 출생 후의 개발하는 동안 그들은 적극적으로 증식 myelinating 희소 돌기 아교 세포를 생성합니다. 이 세포는 일반적으로 기본 해리 문화, 신경 세포 공 배양 연구, 고정 조직되었다. 새로 사용 가능한 트랜스 제닉 마우스 선이 배양 시스템은 전뇌와 소뇌 모두 회색과 백질 영역에 희소 돌기 아교 세포 계통 세포의 증식과 분화를 조사하는데 사용될 수있는 슬라이스. 슬라이스 문화는 출생 초기 마우스에서 준비가되어 1 개월까지에 대한 문화에 보관됩니다. 이 조각은 세포의 행동과 상호 작용을 조사하기 위해 배양 기간 동안 여러 번 이미지를 만들 수 있습니다. 이 방법은 NG2의 세포 분열의 시각화와의 상세한 분석을 가능하게하고있는 동안 희소 돌기 아교 세포의 분화로 이어지는 단계 지역별 의존 할 수 있습니다천만에 NG2 세포 및 희소 돌기 아교 세포 기능 이질성. 이는 생체 내에서 밀접 발견 유사한 셀룰러 환경에서 시간 경과에 영향을 미치는 이러한 세포 및 극한 외부 신호를 조사하는데 사용될 수있는 강력한 기술이다.

대표 데이터의 예는 다음과 같습니다 P8 NG2cre의 전뇌와 소뇌에서 모두 슬라이스 문화를 사용하여 획득 한 것을 : 경제의 제로 성장, NG2creER : YFP를 형질 전환 마우스 라인을 PLPDsRed. NG2 세포 전뇌와 소뇌 조각 (그림 1B-D, 비디오 1) 이러한 세포의 표현형 일 동안 이미지를 만들 수는 고정 후 결정 NG2와 CC1 항체 (그림 1E)과 면역 염색 할 수 있습니다. 이미징 사는 또한 세포 증식?...

Organotypic Slice Cultures to Study Oligodendrocyte Dynamics and Myelination

Organotypic 슬라이스는 문화 희소 돌기 아교 세포 역학 및 수초화을 공부하기

A technique to study NG2 cells and oligodendrocytes using a slice culture system of the forebrain and cerebellum is described. This method allows examination of the dynamics of proliferation and differentiation of cells within the oligodendrocyte lineage where the extracellular environment can be easily manipulated while maintaining tissue cytoarchitecture.

NG2 expressing cells (polydendrocytes, oligodendrocyte precursor cells) are the fourth major glial cell population in the central nervous system. During ...
