Abstract OBJECTIVES/HYPOTHESIS:We have previously demonstrated the potential use of induced pluripotent stem (iPS) cells for regeneration of respiratory epithelium by culturing embryoid bodies (EBs). The aim of the present study was to determine the most effective conditions for EB formation from iPS cells for regeneration of respiratory epithelium.
STUDY DESIGN:Experimental study.
METHODS:iPS cells cultured on a gelatin-coated dish were seeded on low-attachment plates for generating EBs. Under several conditions including the air-liquid interface (ALI) method, with varying cell numbers and suspension times, EBs were transferred to a gelatin-coated dish supplemented with growth factors. The shape, size, aggregation, and adhesion of EBs for iPS cell differentiation were evaluated, and the cultured tissue was histologically examined.
RESULTS:EBs appropriate for differentiation were observed using 1,000 cells after 5 days of suspension culture. Respiratory epithelium-like tissue was histologically observed. The ciliary epithelium was confirmed immunohistologically.
CONCLUSIONS:Based on the varying suspension times and cell numbers with the ALI method, this study presented effective conditions for EB formation from iPS cells for regeneration of respiratory epithelium.
