About this study
Official title: Quantitative Measurements of the Skin Dermal Regeneration After Stromal Vascular Fraction Transplantation
This study is a prospective, exploratory investigation aimed at exploring the efficacy of stromal vascular fraction (SVF) transplantation in treating exhaustion of dermal regenerative capacity during skin expansion. The dermal thickness, texture, and perfusion before and after SVF transplantation would be recorded and analyzed by a series of quantitative devices including laser 3D scanner, Doppler ultrasound, VISIA skin analyzer, CK skin analyzer, and indocyanine green angiography.
Read the detailed description
This study is a prospective, exploratory investigation aimed at exploring the efficacy of stromal vascular fraction (SVF) transplantation in treating exhaustion of dermal regenerative capacity during skin expansion. The dermal thickness, texture, and perfusion before and after SVF transplantation would be recorded and analyzed by a series of quantitative devices including laser 3D scanner, Doppler ultrasound, VISIA skin analyzer, CK skin analyzer, and indocyanine green angiography.
The trial aims to include patients experiencing dermal exhaustion during the process of skin soft tissue expansion. We will extract SVF components from autologous adipose tissue and injected intradermally into the expanded skin. The changes of dermis of expanded skin were recorded before the treatment (baseline), and at 4 weeks and 8 weeks follow-up timepoints after SVF transplantation. More specifically, skin surface area was measured using laser 3D scan; skin thickness and texture were detected by Doppler ultrasound, VISIA skin analyzer and CK skin analyzer; skin blood perfusion was analyzed using indocyanine green angiography.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Stromal vascular fraction transplantationProcedure or surgery
Stromal vascular fraction was extracted from subcutaneous fat harvested from either the abdomen or the posterior inner thigh region. The SVF cell-pellet was washed and was adjusted to 2×10^6 cells/mL. The skin was marked with methylene blue and a total of 0.5ml (around 1×10^6 cells) were transplanted intradermally at the center of each 2cm×2cm squares.
The expander was inflated two times a week using constant pressure inflation method, where the intracapsular pressure was monitored using a pressure meter and the inflation was halted when the pressure reached 100 mmHg. This procedure was repeated until adequate skin area was achieved for subsequent facial restoration surgery.
| Study group | Role | What they receive |
|---|---|---|
| Stromal vascular fraction transplantation | Experimental | Subcutaneous fat was harvested from either the abdomen or the posterior inner thigh region and then digested with 600 U of collagenase (Shanghai Qiaoyuan Biological Pharmaceutical Co., Ltd, Shanghai, China) at 37°C and 150rpm for three hours. After enzymatic digestion, the lower aqueous phase liquid was aspirated to acquire the stromal vascular fraction (SVF). The SVF cell-pellet was washed and adjusted to 2×10^6 cells/mL. The skin was marked with methylene blue and a total of 0.5ml (around 1×10^6 cells) were transplanted intradermally at the center of each 2cm×2cm squares.
The expander was inflated two times a week using constant pressure inflation method, where the intracapsular pressure was monitored using a pressure meter and the inflation was halted when the pressure reached 100 mmHg. This procedure was repeated until adequate skin area was achieved for subsequent facial restoration surgery. Receives: Procedure: Stromal vascular fraction transplantation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Dermal thickness
Using Doppler ultrasound to measure the full-thickness of skin dermis of the expanded skin. The measurements were conducted at the center of the expanded skin and other four points (above, below, left, right) around the center. The average value is taken to represent the dermal thickness of the patient's expanded skin.
Measured: Baseline: before SVF transplantation (Baseline); Follow-up: 4 and 8 weeks after SVF transplantation
Secondary outcomes (1)
Skin surface area
Using the HSCAN771 handheld laser 3D scanner and the VIVID910 3D laser scanning system to measure the surface area of the expanded skin.
Measured: Baseline: before SVF transplantation (Baseline); Follow-up: 4 and 8 weeks after SVF transplantation
