도 23은, 실시예 12에서 NOG 마우스의 전신에 그래프트된 골수종 세포주 MM1s에 대한 치료 실험의 설계, 및 그 결과를 예시 및 보여주는 도, 이미지, 및 그래프이다. MMG49 항체-유래 CAR-T 세포 또는 그 안에 GFP가 도입된 T-세포 (대조구)의 이송 전 및 후의 골수종 세포의 양을 IVIS 이미징에 기초한 형광 강도 측정법에 의해 평가하였다. MMG49 항체-유래 CAR-T 세포-투여된 군에서, 골수 내 MM1s 세포는 거의 완전히 사라졌다.
도 24는, 인간 기원의 인테그린 β7의 아미노산 서열 및 마우스 기원의 인테그린 β7의 아미노산 서열 간의 비교를 예시하는 도이다.
도 25는, 실시예 13에서, 인간/마우스 키메라 인테그린 β7 단백질의 구축 및 단백질을 일시적으로 발현시키는 293T 세포에 대한 MMG49 항체의 결합의 존재 또는 부재를 예시 및 보여주는 도 및 그래프이다.
도 26은, 실시예 14에서 MMG49 항체의 에피토프를 검사하는 실험의 결과를 보여주는 그래프이다. 가로 축 상의 MFI는 MMG49 항체에 대한 결합 강도를 나타내고, 숫자가 높을수록 더욱 높은 활성을 나타낸다.
