Research on stem cells can be divided into three categories : pluripotent stem cell, adult stem cell, and induced pluripotent stem cell. Technology life cycle (TLC) on research stage is analyzed for the three stem cell categories based on diffusion model. Three diffusion models-logistic, Bass, and B...

배아 줄기 세포란 무엇인가? | 배아 줄기 세포(embryonic stem cell; ESC)는 수정 후 4~5일에 태반에 착상되지 않은 배반포 내의 세포덩어리에서 분리할 수 있는 세포로 내배엽, 중배엽, 및 외배엽을 구성하는 거의 모든 종류의 세포로 분화할 수 있어 전분화능 세포(pluripotent stem cell)라고 불린다. 줄기 세포의 존재 가능성은 1950년대부터 제기되었으나, 1981년 Evans와 Kaufman 팀(Evans and Kaufman, 1981)과 Martin 등(Martin, 1981)이 포유류의 배아 줄기 세포의 배양법을 확립한 후. | |
BMIC 모형은 당기 채택자 수에 의한 모수 추정은 불가능한 이유는 무엇인가? | BMIC 모형은 적분상수를 모수로 활용하기 때문에 당기 채택자 수에 의한 모수 추정은 불가능하다(Kim and Hong, 2015). | |
줄기 세포 기술이 다양한 난치성 질환을 치료할 수 있는 새로운 대안으로 부상하고 있는 배경은 무엇인가? | 줄기 세포(stem cell)에서 “stem”은 “유래, 기원, 시작”의 의미로, 조직의 발생 및 분화 과정에서 볼 수 있는 미분화 세포로, 자가복제 능력을 갖고 있어서 인체를 구성하는 다양한 세포와 조직으로 분화할 수 있는 특성을 지니고 있다(National Institutes of Health(NIH) Department of Health and Human Services, 2001). 따라서 줄기 세포 기술은, 질환의 발병 원인 및 과정 연구의 수단으로, 그리고 기존의 의학적 방법으로는 치료가 어려운 다양한 난치성 질환을 치료할 수 있는 새로운 대안으로 부상하고 있다. |
