새로운 메커니즘을 밝힌 논문. 주요 발견 mTEC(mature medullary thymic epithelial cells)는 일반 체세포와 달리 somatic cell fate plasticity가 높아, 다른 조직 특이적 유전자(αTSGs: AIRE-dependent tissue-specific genes)를 이소적으로...

is a multi-stage process, wherein the initial step is the occurrence of an oncogenic mutation in a single somatic cell. The mutation endows cells with clonal advantages, allowing the mutant clone to expand and accumulate additional...
