Illustrative overview of obtained clinical results using homologous skin progenitor cell-based PBBs in Swiss allogeneic cutaneous regenerative medicine. (A) Second-degree and third-degree pediatric hand burn wound (i.e., caused by scalding liquid). Photographic representations of the lesions after early debridement (A1), after PBB application (A2), and after six weeks of treatment (A3). Scale bars = 2 cm. (B) Second-degree deep pediatric torso burn wound (i.e., caused by scalding liquid). Photographic representations of the lesions after early debridement (B1), after PBB application (B2), and after six weeks of treatment (B3). Scale bars = 5 cm. (C) Refractory and painful post-thrombotic cutaneous ulcer lesions treated weekly using PBBs. Photographic representations of the lesions at the time of the treatment initiation (C1), 11 weeks later (C2), and 15 months later during follow-up monitoring (C3). Scale bars = 4 cm. PBB, progenitor biological bandage. Modified and adapted with permission from Laurent et al., 2020 [18].
