Abstract

We constructed a population of myelinated cells with co-culture of neuronal cells and Schwann cells from DRG. Schwann cells and neuronal cells were isolated from dorsal root ganglion (DRG) in embryos of rat in vitro respectively. The cultured Schwann cells and cultured neuronal cells, respectively were co-cultured in a same plate. This procedure contains following four steps: first step of suspension of the embryonic dorsal root ganglion cells, second step of addition of anti-mitoticcocktail, third step of purification of dorsal root cells, and fourth step of addition of Schwann cells to dorsal root ganglion cells. These cells were performed accomplishment of myelination. This myelinated co-culture system was infected by Semliki forest virus and then induced demyelination processing in this myelinated co-culture. We identified myelination and demyelination processing using antibody of peripheral myelin protein 22 (PMP 22) meaning presence of myelinated neuron.

척수신경절의 신경 세포와 슈반세포의 공동 배양으로 수초화 형성 세포 집단이 제조되었다. 슈반세포와 뉴런 세포가 쥐의 배아의 척수신경절로 부터 각각 in vitro에서 분리되었다. 배양된 슈반세포와 뉴런 세포는 동일한 평판접시에서 공동배양 되었다. 본 실험과정은 다음과 같은 4 단계로 구성되어 있다 : 첫 번째 단계는 배아의 척수 신경절 세포의 현탁 과정, 두 번째 단계는 안티 mitotic cocktail의 추가 과정, 세 번째 단계는 척수신경절 세포의 정제 과정, 및 네 번째 단계는 척추 신경절 세포에 슈반 세포의 추가 과정이다. 이들 세포들은 때 수초화가 진행되었다. 이렇게 수초화된 공동 배양은 Semliki forest virus에 의해 감염되었고 그 때 탈수초화 과정을 유발시켰다. 우리는 수초화된 뉴런에 존재하는 peripheral myelin protein 22의 항체를 이용하여 수초화 과정과 탈수초화 과정을 확인하였다.
