High‐throughput lipidomic profiles sampled with electroporation‐based biopsy differentiate healthy skin, cutaneous squamous cell carcinoma, and basal cell carcinoma

Background The incidence rates of cutaneous squamous cell carcinoma (cSCC) and basal cell carcinoma (BCC) skin cancers are rising, while the current diagnostic process is time‐consuming. We describe the development of a novel approach to high‐throughput sampling of tissue lipids using electroporation‐based biopsy, termed e‐biopsy. We report on the ability of the e‐biopsy technique to harvest large amounts of lipids from human skin samples. Materials and Methods Here, 168 lipids were reliably identified from 12 patients providing a total of 13 samples. The extracted lipids were profiled with ultra‐performance liquid chromatography and tandem mass spectrometry (UPLC‐MS‐MS) providing cSCC, BCC, and healthy skin lipidomic profiles. Results Comparative analysis identified 27 differentially expressed lipids (p
