A. Limitations
So far we have seen a new approach of using stemcells for targeting cancer site and a new concept of
treatment. However it might seem fascinating, it is important to note that significant impediments remain
before the true potential of this novel therapy can be fully realized. Here in this section we are going to
mainly focus on the limitations of neural stemcells esp

해당 연구가 진행되었던 배경은 인슐린을 생산하는 섬세포(islet cell)는 신경단위세포(neuron)와 유사하다는 점과 배아 줄기세포(embryonic stemcell)를 인슐린 생산 세포로 변환시킨 선행 연구 사례를 통해 neural progenitor cell을 이용하게 되었다. 또
5. Science誌에 실린 황우석 교수의 연구 성과(1차 논문)
황우석 교수가 한 연구는 복제배아를 이용한 줄기세포를 이용해 난치병을 치료하는 것이다. 난치병의 예로 당뇨병이나 골 관절염 파킨스 병 같은 걸 들었는데, SCNT(somatic cell nuclear transfer)technology 를 이용해 환자의 DNA를 가진 stemcell을 만들어 낸

(1) Big Three U.S. Companies
Automobile companies are facing vigorous battle in North America, and some companies have to deal with their net loss and huge amount of debt. General Motors Co., Ford Motor Co., and Chrysler Group LLC, so called ‘Big Three’ in automotive industry got through major crisis in 2008, and GM ended up filing
