초록

본 연구에서는 세포의 성장속도, 배양표면 부착, 체내 특이성을 유지에 중요한 요소인 세포외 기질 물질에 따른 심근세포주(HL-1 cell)의 성장, 생존률 및 표현형 등을 분석했다. 서로 다른 5 가지의 세포외 기질 환경을 조성하여 세포 성장에 미치는 영향에 대하여 분석했다. 세포외 기질 물질이 처리된 배양 표면의 물리적인 형태는 원자현미경을 통하여 분석했으며, 세포의 표면부착, 성장 및 증식과 생존률 및 표현형은 역상형광현미경 및 면역염색법을 통해 분석했다. 본 연구를 통하여 서로 다른 세포외 기질 물질이 세포의 부착 및 성장 속도에 영향을 미치며, 심근세포의 특이성을 나타내는 단백질의 형성에도 차이를 보이는 것을 확인했다.

The extracellular matrix (ECM) is a key factor affecting cell growth and adhesion to the culture surface, and it is also important for maintaining the innate characteristics of cells. Here, we describe the effects of the ECM on cardiomyocyte (HL-1 cell line) growth, viability, phenotype, and contractile ability. Five different ECM materials were investigated to analyze their effects on the cell growth. The physical morphology of the ECM-coated surfaces was scanned with an atomic force microscope (AFM), and the attachment, growth, proliferation, viability, and phenotype of the cells were analyzed using fluorescence immunostaining and an inverted phase contrast microscope.
