Abstract
Description
도 1a 내지 도 1d는 엄격한 무이종(xeno-free) 및 공급자 없는(feeder-free) 조건에서 말초 혈액 단핵 세포로부터 생성된 인간 유도된 다분화능 줄기 세포 (iPSC)의 구현예를 나타낸다. (도 1a) 현미경측정에 의해 측정된, 비트로넥틴 상의 E8 플렉스 배지 내의 iPSC 콜로니의 대표적 양태 (스케일 바 1000 ㎛ 상단, 200 ㎛ 하단). (도 1b) 역전사 실시간 PCR (RT-qPCR)에 의해 측정된, 섬유모세포 (밝은 회색 바), 배아 줄기 세포 (ESC, 백색 바) 및 iPSC (대각선 바)에서의 다분화능 유전자 (NANOG, POU5F1 및 SOX2)의 발현. (도 1c) iPSC의 대표적 유동 세포계측 분석으로, 이는 다분화능 마커 (SSEA4 및 TRA-1-81 [게이티드 세포(gated cell)의 90.8%], TRA-1-81 및 NANOG (게이티드 세포의 88. 8%) 발현의 높은 균질성을 보여줌. (도 1d) 면역형광법에 의해 측정된 피부 섬유모세포 (하부 열)와 비교한 iPSC (상단 열)에서의 다분화능 마커 (SOX2, TRA-1-81, NANOG, SSEA4 및 POU5F1)의 발현 (스케일 바 200 ㎛). 삽입물은 핵 (DAPI) 염색을 나타낸다.
도 2a 내지 도 2n은 iPSC의 시험관내 분화를 나타낸다. (도 2a) RT-qPCR에 의해 측정된, iPSC (밝은 회색 바)와 비교된 경우, iPSC-유래된 완전 내배엽 (백색 바)에서의 내배엽-특이적 유전자 (SOX17, FOXA2, CXCR4, GATA4)의 상향조절, 및 다분화능 유전자 (SOX2, NANOG, POU5F1)의 하향조절. 결과를 다양한 시험 유전자에서 로그 배수 변화로 나타내었다. (도 2b) 면역형광법에 의해 측정된, 시험관내 분화시 내배엽-특이적 마커(SOX17, FOXA2, CXCR4, GATA4)의 발현 (스케일 바 200 ㎛). 결과를 완전 내배엽 (상단 열) 및 미분화된 iPSC (하단 열)에 대해 나타내었다. 삽입물은 핵 (DAPI) 염색을 나타낸다. (도 2c) FOXA2, CXCR4 및 SOX17 마커에 대한, 완전 완전 내배엽에서 분화된 iPSC의 대표적 유동 세포계측 분석. 세포의 87.2%는 FOXA2+ 및 CXCR4+였고, 그의 98.4%는 또한 SOX17+였다 (삼중-양성 세포의 85.8%). (도 2d) 간 전구체 세포를 발생시키는, iPSC-유래된 복부 후부 전장 세포에서의 HNF4α의 증가된 발현. 결과를, iPSC, 완전 내배엽에서 분화된 iPSC, 또한 후부 전장에서 분화된 iPSC에서의 HNF4α 유전자의 mRNA 발현에서의 배수 변화로 나타내었다.
