In this study, we prepared surface-smooth and porous poly(lactic-co-glycolic acid) (PLGA) microsphereswith different diameters, different sizes of pores and different densities of pores using a simple oil/wateremulsion method and varying the preparation conditions, including the molecular weight of PLGA, thecomponents of the PLGA and the addition of porogen. The surface-smooth nonporous and porous PLGAmicrospheres were also further modified with collagen I. The characteristics of these PLGA microspheres,including original and collagen I-coated PLGA microspheres, were evaluated in a three-dimensional (3D)culture of ovarian cancer HO8910 cells. The HO8910 cells can growth better on original porous andcollagen I-coated PLGA microspheres, and express remarkably E-cadherin. These results indicate thatporous PLGA microspheres and collagen-coated PLGA microspheres are promising candidates as ovariancancer cell culture microcarriers for pathological study and high-throughput antitumor drug screening.
