Optimal Pore Size of Honeycomb Polylactic Acid Films for In Vitro Cartilage Formation by Synovial Mesenchymal Stem Cells
Figure 6
Temporal alteration in histological images of in vitro cartilage formation of synovial MSCs plated on PLA films with 5 μm pores. MSCs ( in 500 μL medium) were plated, cultured in chondrogenic induction medium for three weeks, and stained with safranin O. The arrow indicates the PLA film.
