Abstract
Description
도 2는 골수유래 중간엽 줄기세포(BM-MSC)의 면역 표현형과 분화 잠재능력을 보여주는 것이다. (A) 세포 표면 항원(CD14, CD34, CD45, CD73 및 CD105)의 발현을 유동세포계수법을 이용하여 평가하였다. (B) 양성 개체군의 대표 히스토그램으로 11명의 환자에 대한 평균과 표준편차를 나타내고 있다. (C) 내생의 알칼리 포스파타아제(endogenous alkaline phosphatase)의 활성에 대해 양성으로 염색된 골수유래 중간엽 줄기세포로서, 이는 골 형성 배지(OM;Ⅰ) 내에서 골 세포로의 분화를 나타내는 것이며, 대조군 배지(CM;Ⅱ)에서는 음성으로 염색되었다. 지방 방울(lipid droplet)에 대해 양성으로 염색된 골수유래 중간엽 줄기세포로서, 이는 지방 형성 배지(AM;Ⅲ) 내에서 지방 세포로의 분화를 나타내는 것이며, 대조군 배지(CM; Ⅳ)에서는 음성으로 염색되었다(× 200).
도 3은 조직학적 및 면역 조직화학적 분석을 보여주는 것이다.
조직학적 분석을 H&E(A, B) 및 MTC(C, D) 염색에 의해 평가하였다(× 100). 골수유래 중간엽 줄기세포 치료법은 Laennec fibrosis scoring system에 따르는 F4C 치료 전(A, C)에서 F4B 치료 후(B, D)로의 경변증 개선을 유도하였다.
간 생검 표본으로부터의 조직 절편을 Picrosirius Red 염색한 결과, 적색으로 염색된 콜라겐 비율이 치료 전(E)에서 치료 후(F)로의 변화를 나타내었다(× 40). Picrosirius Red로 염색된 콜라겐의 상대적인 면적을 이미지 분석 프로그램을 이용하여 분석하였다. 콜라겐의 비례 면적 비율이 치료 전 22.61± 8.39%에서 골수유래 중간엽 줄기세포 치료법 실시 후 17.70 ± 6.93%로 감소하였다. 데이터는 평균 및 표준편차이다. *p<0.001
도 4는 섬유증과 관련된 유전자 발현 분석을 보여주는 것이다.
골수유래 중간엽 줄기세포 치료방법 실시 후, 실시간 PCR로 분석한 결과, (A)TGF-β1, (B)collagen-1, (C)α-SMA의 상대적인 발현(2-ΔΔCt 값)은 각각 3.81± 1.39에서 2.65± 1.21(*p=0.013)로, 4.51± 2.62에서 3.15 ± 2.82(*p=0.021)로, 4.27± 1.89에서 2.34± 1.60(*p=0.007)로 유의하게 감소하였다. 데이터는 평균 및 표준편차이다.
