Growth of human keratinocytes (HaCaT) after 7 days on different specimens: (A) on steel and (B) on Ti6Al4V. Note that the cell density is nearly confluent. Only the cluster microstructure without LIPSS (DC20) indicated some free spaces with a confluence < 97.4%. HaCaTs could spread into and over the dimple structure and were not inhibited in extension. (FE-SEM Merlin VP compact, 1000× magnification, 5 kV, HE-SE detector scale bars = 20 µm; quantification of confluence by ImageJ).
