Morphological classes and morphotypes of MPh on the 6th day of cultivation on standard culture plastics and biopolymer scaffolds of various composition. MN were isolated from the patient's blood before the stent was installed and after the stent was installed. MN were cultivated on culture plastic and on biopolymers scaffolds of various compositions (scaffolds 1, 2, 3, 4, 5) in 96-well culture plates (10⁵ cells/well) in DMEM medium with 10% fetal serum in CO₂-incubator. After 6 days of culture the cells were fixed in the wells of the plate with 2.5% glutaraldehyde and samples were prepared for SEM using a standard protocol.

An asterisk indicates the cases where the value after the stent installation (before stenting) was significantly different from the value before the stent installation (after stenting) (p ≤ 0.05).
