A cat who is a 15-year-old and spayed female visited an animal clinic with severe coughing symptoms. Since the cat’s coughing symptoms had worsened from the age of 10 and X-rays showed a bronchial pattern in the lungs, it was diagnosed as Chronic Obstructive Pulmonary Disease (COPD). She received three injections of stem cells isolated from the amniotic membrane on days 0, 7, and 23. Although there was no improvement in the clinical findings on the x-ray, the number of coughing was significantly reduced. In addition, even after long-term follow-up post treatment for a month, she was stable with almost no coughing.

중간엽 줄기세포(MSC)를 체외배양할 때 사용하는 소태아혈청 (FBS)의 생물학적 불안전성은 이를 임상적으로 사용하는데 있어 제한점으로 작용한다. 본 연구에서는 소태아혈청 및 인간의 제대혈청을 사용하여 인간의 양막유래 중간엽 줄기세포 (HAM)를 각각 배양한 후, 세포의 성장속도와 유전자 및 단백질의 발현 양상을 비교하였다. 제왕절개 후 얻은 양막으로부터 HAM을 분리하여 10% FBS, 5% HCS 혹은 10% HCS가 각각 첨가된 DMEM 배양액에서
