Fig. 5.8, Cultivation of hmvECs on 2PP patterned OC-I. (a)–(d) HE-stained cells grown on glass slides decorated with different OC-I structures. (e) Microvascular endothelial cell (Upcyte® HDMECs, Medicyte GmbH, Heidelberg) grown on OC-GM structures. Nuclei appear blue due to DAPI staining. Immunohistological staining of β-tubulin (filaments) appears green
