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)

Primary Outcome Measures
NameTimeMethod
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.

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.

Change in patient's skin condition0-27 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.

Secondary Outcome Measures
NameTimeMethod

Changes in skin surface morphology assessed by digital imaging.

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.

Record of adverse events0-27 weeks

Evaluation of safety of the method of cells' application assessed by adverse events
