A micro-groove structure for
cell culture includes a micro-groove body and a a
microstructure unit. The micro-groove body is formed with a
microculture space which has an opening and which is defined by a space-defining wall. The
microstructure unit is formed on the micro-groove body and is located in the
microculture space. The
microstructure unit has microstructures which protrude from the space-defining wall into the
microculture space. The microstructures cooperatively define a
concave surface which tapers in a direction away from the opening of the microculture space and which is used to support cells. A
cell culture device includes a substrate and
cell culture well units. The
cell culture well units are disposed in the substrate. Each of the
cell culture well units has a main well body and at least one the micro-groove structure.
