Spheroid culture has been used for suspension cultures of anchorage-dependent
cells. In this study, we developed a new method for the suspension cultures of
anchorage-dependent animal cells using polymer nanofibers.
Poly(lactic-co-glycolic acid) nanofibers (785 nm in average fiber-diameter, 88 μm
in average fiber-length) fabricated by the electrospinning method were added to
each suspension culture of human embryonic kidney 293 cells and human dermal
