Safety of Repaircell in Healthy Volunteers

Study Overview
=================
Brief Summary
-----------------
Allogenic differentiated adipocytes (ANT-adip-AL) is produced by well-established techniques including cell harvesting from lipoaspirates obtained from healthy donors, expansion of adipose tissue derived stem cells, and differentiation into pure and immature adipocytes. This was an open-label study. Subjects were received subcutaneous injection of ANT-adip-AL and followed for 8 weeks according to the clinical trial protocol.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Adverse events | Evaluate the safety at week 8 whether any kind of Adverse event occurs | week 8 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Immunological response II | Infiltration of immune cells by histology based on five basic parameters: (0) No evidence of immune cell infiltration in all area of the tissue, (1) Slight immune cell infiltration visible in partial area of the tissue (barely visible), (2) Obvious immune cell infiltration visible in partial area of the tissue, (3) Slight immune cell infiltration visible in all area of the tissue, and (4) Intense immune cell infiltration visible in all areas of the tissue. | week 8 | 
| Immunological response I | CD4 (cluster of differentiation 4)/CD8 (cluster of differentiation 8) ratio | change from baseline CD4/CD8 ratio at week 8 |
