Pilot Study of Skin Quality Improvement After Adipose-drived Stem Cell Transfer in Irradiated Breasts

Pilot Study of Skin Quality Improvement After Adipose-drived Stem Cell Transfer in Irradiated Breasts

The aim of this study is to evaluate the skin quality of using adipose-drived stromal vascular fraction (SVF) cell taken by automatic centrifuge for adipose-drived cell isolation system into irradiated breasts.

10 participants who taken conservative mastectomy will be enrolled

1. Process

   • adipose tissue is obtained from the subject's thigh or abdomen
   • adipose-drived stromal vascular fraction(SVF)cell isolation using automatic centrifuge system
   • adipose-drived stromal vascular fraction(SVF)cell graft into the irradiated breast.

2. Duration of study

   • entire duration: approximate 30weeks
   • Follow-up period: 12 weeks
   • Enrollment period: 12 weeks

3. Study design - Randomized, prospective, pilot study

• Subjects who understand the study contents and sign the informed consent

Exclusion Criteria:

• Subjects who have radiodermatitis
