Brief Summary:
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.

Condition or disease Intervention/treatment Phase

Detailed Description:

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

Arm Intervention/treatment
Experimental: Adipose SVF cell
adipose SVF cell transfer to the half of irradiated breast
Biological: Adipose SVF cell
adipose SVF cell transfer to the half of irradiated breast

Active Comparator: Normal saline
Normal saline inject to the half of irradiated breast
Biological: Normal saline
Normal saline inject to the half of irradiated breast




Primary Outcome Measures :
  1. The change in the breast skin thickness of the pre and post SVF graft from baseline at 12week after procedure [ Time Frame: change in the breast skin thickness from baseline at 12 week ]
    The efficacy is assessed by breast skin thickness measured by radiologist using breast ultrasonography
