| Outline of Final Research Achievements |
We aimed to examine the report (Lioni et al, 2007) using three dimensional (3D) culture, but we found E-cadherin expression in esophageal cancer cell line, TE-8. Thus, we changed the study theme to establishment of 3D keratinocyte culture system. We formed keratinized stratified squamous epithelium using human primary keratinocytes directly seeded on the membrane of culture inserts under airlifted conditions in EpiLife medium supplemented with calcium, ascorbic acid and KGF. Under similar conditions, mouse keratinocyte cell lines, COCA and K38, formed keratinized and non-keratinized stratified squamous epithelium, respectively. These multilayers formed functional tight junctions as revealed by transepithelial electrical resistance. The 3D culture system we have established is useful to study tight junction formation and function.
