Abstract

This study, the ultrastructure of radial glial cells in the fetuses (the 60th, 90th, 105th 120th of gestation) and neonate brains of korean native goat were investigated by immunohistochemical method and transmisson electron microscopy. 1. In the 60th day of gestation, mitochondria and many glycogen body were observed in the radial glial cells. 2. In the 90th day of gestation, mitochondria, many glycogen body and rough endoplasmic reticulum were observed. 3. In the 95th day of gestation, Golgi's apparatus was found. 4. In the 120th day of gestation, Endfeets of radial glial cell attached vessel wall were observed.

한국재래산양의 임신60, 90, 105, 120일령 태아 및 신생아의 뇌를 대상으로 면역조직화학적방법을 통하여 면역반응을 나타낸 방사아교세포를 투과전자현미경적 방법을 이용하여 그 미세구조를 연구한 결과 임신 60일령 태아의 방사아교면역반응세포는 소수의 사립체와 많은 당원질 및 과립형질내세망이 관찰되었으며 임신90일령 태아 이후에서도 소수의 사립체, 많은 당원질 그리고 소수의 형질내세망이 관찰되었으며 임신95일령 태아에서 골지체가 관찰되었다. 그리고 임신 120일령에서 혈관에 부착되어 종말발을 뻗고 있는 GFAP 면역반응세포를 관찰할 수 있었다.
