Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary Objective: use immunofluorescence (IF) on previously obtained biopsies to analyze and quantify changes in adipose tissue of subjects injected with poly-L-lactic acid (PLLA) or saline.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sixteen female adults that participated in SPLASH study will be enrolled in this retrospective study. It aims to analyze previously collected biopsy samples from participants who completed the "SPLASH: Split-Body Randomized Clinical Trial of Poly-L-Lactic Acid for Adipogenesis and Volumization of the Hip Dell" study. The study will use immunohistology to assess changes in adipose tissue associated with treatment with PLLA (poly-L-lactic acid). We hypothesize that specimens treated with PLLA will be found to have more adipocyte-derived stem cells and preadipocytes undergoing mitosis and differentiation compared to control specimens.
