    Abstract

    We have utilized patients' own oral mucosa as a cell source for the fabrication of transplantable epithelial cell sheets to treat limbal stem cell deficiency and mucosal defects after endoscopic submucosal dissection of esophageal cancer. Because there are abundant microbiotas in the human oral cavity, the oral mucosa was sterilized and 40μg/mL gentamicin and 0.27μg/mL amphotericin B were added to the culture medium in our protocol. Although an oral surgeon carefully checked each patient's oral cavity and although candidiasis was not observed before taking the biopsy, contamination with Candida albicans (C.albicans) was detected in the conditioned medium during cell sheet fabrication. After adding 1μg/mL amphotericin B to the transportation medium during transport from Nagasaki University Hospital to Tokyo Women's Medical University, which are 1200km apart, no proliferation of C.albicans was observed. These results indicated that the supplementation of transportation medium with antimycotics would be useful for preventing contamination with C.albicans derived from the oral mucosa without hampering cell proliferation.
