Trial Outcomes & Findings for Effect of Concentrating Endogenous Stromal Cells in the Fat Graft Using TGI Device (NCT NCT01924364)

NCT ID: NCT01924364

Last Updated: 2018-05-11

Results Overview

Facial appearance and persistence of treatment effect will be assessed using high resolution CT scanning with 3D reconstruction. Patients will be followed for 24 months after treatment to define long term outcomes.

Tissue Genesis Cell Isolation System™ (CIS): In this study, we will concentrate the adipose stromal cells (ASCs) in the fat graft material to assess whether this modification will increase fat graft retention over time. The concentrated fat to be injected into the subject from the fat grafting procedure will be processed by the Tissue Genesis Cell Isolation System™ (CIS) device. The volume retention in areas treated with ASC concentrated fat grafts will be compared with regions treated with standard fat grafts in the same patient. Additionally, data from our current study assessing volume retention after fat grafting for facial deformities (IRB # PRO09060101) will be used for comparison.
