Brief summary
The aim of this study is to compare clinical outcomes of patients with large scars or Cutis laxa treated with injections of autologous stromal vascular fraction cells (SVF) and adipose-derived mesenchymal stem cells (ADSC).
Detailed description
Patients suffering from cutis laxa senilis and scars (atrophic, hypertrophic, developed due to surgery, trauma, diseases such as acne vulgaris, post-burn scars) will be treated with product containing - human autologous stromal vascular fraction (SVF) cells and human autologous adipose-derived mesenchymal stem cells (ADSC)
Interventions
non-ablative fractional laser therapy of skin
Subcutaneous injection of autologous ADSC
Subcutaneous Normal saline injection
Sponsors
Study design
Intervention model description
Patients receive injections of autologous SVF or ADSC cells isolated in the laboratory from adipose tissue.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in patient's skin condition | 0-27 weeks | Evaluation of the effectiveness of the method of application of stem cells in the described indications by evaluating the time after which there will be an improvement of 50% in the point evaluation scale of the quality of life of the patient in relation to the baseline values. Scale 1: Impact of skin problems on the quality of life. The aim is to assess to what extent skin ailments have affected the patient's life in the last 2 weeks. A five-level scale of evaluation (from 'very strong' to 'not applicable') .The very strong value means the worst result, while the not applicable value is the best result. |
| Evaluation of skin problems. Assessment of skin related complaints since the last visit. | 0-27 weeks | Scale 2: A seven-level grading scale (from 0 to 6).The value 0 means the best result, while 6 is the worst result. |
| The assessment of the scar by the patient. | 0-27 weeks | Scale 3: Six-point scale (from '1' to '6'). The value 1 means the best result, while 6 is the worst result. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in volume of the skin (USG) | 0-27 weeks | Changes in the volume of the fat layer at the application site assessed by skin (USG) thickness. |
| Changes in skin surface morphology (digital imagining) | 0-27 weeks | Changes in skin surface morphology assessed by digital imaging. |
| Record of adverse events | 0-27 weeks | Evaluation of safety of the method of cells' application assessed by adverse events |
