Initial Attatchment of rMSC and MG-63 Cells on Patterned Bioglass® Substrates

A soft lithography technique was used to introduce surface patterns on the surface of sintered bioactive glass substrates. Osteoblast-like MG-63 cells and rat mesenchymal stem cells (rMSC) seeded on micropatterned bioactive glass surfaces showed different behavior with rMSC exhibiting a better initial attachment than MG-63 cells. Both cytoskeleton formation and cell spreading of rMSC were supported by the bioactive surfaces. In addition, the structured surfaces seemed to guide MG-63 cells to a larger extent than rMSC. The in vitro results are important considering the continuous development of bone tissue scaffolds based on silicate bioactive glasses.
