It is found that cell proliferation, migration, alignment, spatial distribution, F-actin protein expression and gene expression are all remarkably distinct on these microgrooved samples and the smooth control PLGA substrate. The associated underlying mechanisms were further analyzed and discussed using real-time living cell monitoring, confocal laser scanning microscopy and gene microarray. Our preliminary results suggested that 3D microstruc- ture could affect cell behaviors in a much more extensive manner than what we had understood before.展开更多
