도 4는 본 발명의 펩타이드성 바이오핀(BPin-44: 막단백질의 N-말단에 세포 침투 펩타이드가 위치한 바이오핀; BPin-55: 막단백질의 양 말단에 세포 침투 펩타이드가 위치한 바이오핀)을 세포에 처리하여 얻은 공초점 현미경(confocal microscope) 사진도이다.
도 5 및 도 6은 녹색 형광 염료(Green fluorescent dye, Dil)로 염색된 랫트의 중간엽 줄기세포(rat mesenchymal stem cells, MSCs)에 본 발명의 바이오핀 BPin-44와 BPin-55를 각각 2 시간 처리하여 적색 형광 염료(red fluorescent dye, DiO)로 염색된 심장세포(cardiac cells H9c2)가 깔려 있는 배양 접시에 부착(adhesion)시켜 얻은 형광현미경 사진도(도 5)와, 형광 분석기(fluorescent spectrometer)로 흡광/방출(484 nm/501 nm) 값을 얻어 측정한 그래프이다(도 6).
