   2. An anterior elbow scar causing 20-60% restriction of elbow extension
   3. A dorsal or palmar lesion of a single finger causing 20-60% restriction of flexion or extension
3. Subject's burn scar to be treated is <100 sq cm in size
4. Injury occurred ≤ 36 months prior to screening

2. Subjects for whom a post auricular biopsy cannot be collected for azficel-T production
3. Sunburn or sun damage in the area that will be used for biopsy
4. Plans to initiate any other new scar therapy during the study period
5. Treatment with an investigational product or procedure within 30 days prior to study enrollment or plans to participate in another clinical trial during the course of this study
6. History of active autoimmune disease or organ transplantation
7. Diagnosis of cancer, including basal cell carcinoma, unless successfully treated or in remission for a minimum of 6 months
