Abstract
본 발명의 코어와 쉘이 명확히 구분된 코어-쉘 섬유상 세포전달체는 쉘의 알지네이트 함량을 최적화하여 코어에 위치한 세포에 산소 및 영양분을 원활히 공급할 수 있고, 이때 세포는 산소와 영양분의 공급이 원활한 쉘과의 경계부분에서 네트워크를 형성할 수 있다. 상기 세포전달체는 하이드로겔 형태로 성형이 용이하여 작거나 복잡한 형태의 조직 손상부분에도 직접 채워넣어 이식할 수 있다.
Description
도 2는 코어 및 쉘 두께에 대한 알지네이트 농도(a 내지 e) 및 주입 속도(f 내지 j)의 영향을 나타낸 도이다. (a) 및 (b)는 각각 알지네이트 농도 변화에 대해 측정된 쉘과 코어의 두께를 나타낸 도이다. (c 내지 e)에는 각기 다른 알지네이트 농도(c; 2%, d; 3% 및 e; 5%)로 사용하여 제조한 코어-쉘 섬유상 형태를 나타낸 광항적 이미지이다. (f) 및 (g)는 각각 주입 속도 변화에 대해 측정된 쉘과 코어의 두께를 나타낸 도이다. (h 내지 j)에는 각기 다른 주입 속도(h; 20 ml/h, i; 50 ml/h 및 j; 80 ml/h)로 사용하여 제조한 코어-쉘 섬유상 형태를 나타낸 광항적 이미지이다. 스케일 바=250 μm.
도 3은 다양한 알지네이트 농도(2%, 3% 및 5%)로 제조한 코어-쉘 구조 섬유상 하이드로겔 세포전달체의 기계적 특성을 나타낸 도이다. 변화하는 주파수(0.1 Hz로부터 10 Hz까지)에서 동적 기계적 분석에 의해 (a) 저장 탄성률 및 (b) 손실 탄성률을 기록하였다. 저장 탄성률은 알지네이트 농도가 증가함에 따라 눈에 띠게 증가한 반면, 손실 탄성률에서는 큰 변화는 관찰되지 않았다.
도 4는 21일까지 코어-쉘 하이드로겔 운반체 내에서 배양시간에 따른 (a) MSC의 증식, (b) 세포생존율 및 (c) 코어 두께 변화를 나타낸 도이다. 결과를 양성 대조군으로 사용한, 순수 콜라겐 하이드로겔 내에서 배양된 MSC에 대해 측정한 값과 서로 비교하였다. 7일째에 유사한 값을 나타내었던 세포 증식은 14일 및 21일로 배양 기간이 길어짐에 따라 차이가 나기 시작하였다(코어-쉘<콜라겐, *p<0.05, 통계적으로 상이함). (b)는 트리판 블루 스크리닝과 혈구계 계수에 의한 상기 두 개 군에 대해 정량된 live/dead cell 비를 나타낸 것으로 두 경우 모두 유사한 수준을 나타내었다(모든 시점에서 약 70%의 생존율). (c)는 21일까지 측정된 콜라겐 코어 수축을 나타낸 것으로 코어 크기는 약 1050 μm(초기)로부터 7일에 900 μm, 14일에 500 μm 및 21일에 350 μm로 눈에 띄게 감소하였다.
도 5는 각기 다른 배양 시기에서 (a, c, e 및 g) MSC를 포획한 코어-쉘 하이드로겔 전달체 및 (b, d, f 및 h) MSC를 포함하는 콜라겐 겔의 광학적 현미경 이미지를 나타낸 도이다. 분주 시 초기 둥근 형태를 갖는 MSC(a 및 b)는 7일에 방추형으로 변형되고(spindle shaped; c 및 d) 이후 14일에 고도로 신장되었다(highly elongated; e 및 f). 21일에는 세포가 널리 증식되어 거의 컨플루언스에 도달하였다(g 및 h). 코어-쉘 운반체에서 콜라겐 코어 부분은 배양 시간이 증가함에 따라 상당히 수축되었다. 스케일 바=350 μm.
도 6은 일정 기간 배양(7일; a 및 b, 14일; c 및 d, 및 21일; e 및 f) 후 코어-쉘 섬유상 운반체 내의 세포골격 과정 및 신장 형태를 나타낸 공초점 레이저 주사 현미경 이미지를 나타낸 도이다. 세포 핵은 파란 색(DAPI)으로, 세포골격은 빨간 색(Alexa Fluor Phalloidin 548)으로 염색하였다. 스케일 바=850 μm(a, c 및 e) 및 350 μm(b, d 및 f).
도 7은 코어-쉘 섬유상 하이드로겔 운반체 내에서 14일 및 21일에 걸쳐 배양한 MSC의 골형성 분화를 나타낸 도이다. (a) BSP, (b) OPN 및 (c) OCN 유전자의 mRNA 발현 수준을 정량적으로 확인하였다. *는 유의적인 차이를 나타낸다(p<0.05, by ANOVA).
도 8은 MSC를 포획시킨 코어-쉘 하이드로겔 운반체의 생체 내 골형성능을 나타낸 도이다. 상기 사용한 실험군은 운반체 단독('w/o cell'), 미분화 MSC를 포함하는 운반체('non-osteogenic') 및 골형성 배지에서 7일간 분화시킨 MSC를 포함하는 운반체('osteogenic')을 포함한다. 이식 6주 후 ?CT에 의해 골재생을 분석하였다; (a)는 5 mm-직경의 결손 부분 주위에서 신생 골형성(오렌지색)을 나타내는 ?CT 구조적 이미지이다. (b) 내지 (d)는 각각 신생 골부피의 백분율, 골 표면적 및 골 표면밀도를 나타낸 정량분석 결과이다. 유의한 차이가 관찰되었다(*p<0.05, by ANOVA).
도 9는 이식 6주 후 헤마톡실린 및 에오신(H&E) 및 마송삼색(Masson's trichrome) 염색 후 이식된 시료의 조직학적 이미지를 나타낸 도이다; (a) 운반체 단독, (b) 미분화 MSC를 포함하는 운반체 및 (c) 분화된 MSC를 포함하는 운반체. (d)는 (c)에서 새롭게 형성된 뼈를 확대한 이미지이다. 화살표: 결손 가장자리, NB: 신생 골, HB: 호스트 골. 스케일 바= 1 mm(a 내지 c) 및 200 μm(d).
