The present invention relates to a stem cell composition for venous administration, the composition containing between 1×107 and 5×108 cells/ml of stem cells present as single cells and having a diameter of between 10 and 20 μm. The present invention makes it possible to provide a stem cell composition suitable for venous administration, and makes it possible to relatively efficiently enhance the efficacy with which vascularly administered stem cells stably reach target tissue and exhibit an action, and can therefore dramatically increase the efficacy of cell therapy using stem cells.La présente invention concerne une composition de cellules souches pour administration veineuse, la composition contenant entre 1 × 107 et 5 × 108 cellules/ml de cellules souches présentes sous forme de cellules uniques et présentant un diamètre compris entre 10 et 20 µm. La présente invention rend possible l'obtention d'une composition de cellules souches adaptée à une administration veineuse, et rend possible l'amplification relativement efficace de l'efficacité avec laquelle les cellules souches administrées par voie vasculaire atteignent de façon stable les tissus ciblés et présentent une action, et peuvent donc augmenter de façon spectaculaire l'efficacité d'une thérapie cellulaire utilisant des cellules souches.본 발명은 10 내지 20 ㎛의 직경을 가지고, 단세포로 존재하는 줄기세포를 1×107 ~ 5×108 세포수/ml로 함유하는 것을 특징으로 하는 정맥 투여용 줄기세포 조성물에 관한 것이다. 본 발명에 따르면, 정맥 투여에 적합한 줄기세포 조성물을 제공할 수 있어, 혈관 내로 투여된 줄기세포가 안정적으로 표적 조직에 도달하여 활성을 나타내는 효능을 보다 효율적으로 높일 수 있으므로 줄기세포를 이용한세포치료 효능을 획기적으로 증진시킬 수 있다.
