Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1. The first treatment group will be hypertrophic scars receiving injections of adipose-derived stem cells (ASCs) suspended in ASC conditioned medium. The suspended ASCs will be injected into hypertrophic scar with a dose of 1,000,000 cells in 1 ml of medium for a 1x1 cm2 area of hypertrophic scar. This trial will target 1x1 cm2 - 3x3 cm2 area of hypertrophic scar. Injection will be conducted three times, with 7-10-day interval between each injections.
Injections will be done by a single doctor.
2. The second treatment group will be hypertrophic scars receiving injections of ASC conditioned medium without ASCs in it, with a dose of 1 ml of medium for a 1x1 cm2 area of hypertrophic scar. This trial will target 1x1 cm2 - 3x3 cm2 area of hypertrophic scar. Injection will be conducted three times, with 7-10-day interval between each injections.
Injection will be performed by the same doctor as the doctor in the first treatment group.

The volume of injections given will be recorded in a case report form and will be audited at the end of the study. The method of allocation used is consecutive allocation based on recruitment process following the order of: 7 subjects receiving ASC and 7 subjects receiving ASC conditioned medium.

Summary
Brief summary
This study aims to evaluate the effectivity of adipose-derived stem cells (ASCs) in alleviating hypertrophic scars. The subjects participating in this study will be divided into three groups: (1) those receiving ASCs injection; (2) those receiving ASC conditioned medium injection; (3) those receiving corticosteroid (triamcinolone acetonide 10 mg/mL) injection. It is expected that ASCs can alleviate hypertrophic scars in terms of symptoms, scar tissue structure, elasticity, color, and area in a similar or greater extent compared to ASC conditioned medium and corticosteroid (the current first line treatment of hypertrophic scar).
