Fig. 10. Average projected cell areas of elongated cells (cell elongations higher than 1.3) and round cells (cell elongations lower than 1.3) on substrates patterned with 600 nm deep grooves and pitches between 400 nm and 4000 nm and on smooth substrates (SiOx and TCPS). The culture medium was SHEM and no FBS was added. The average projected cell areas were similar on SiOx and on TCPS.
