Claim:
1. A microfluidic platform for cell culturing, comprising: a first reservoir comprising a first supply unit that has an annular empty space with an opened top surface such that a first cell to be cultured and a culture medium are supplied; a first compartment comprising a first culture unit that has an annular empty space surrounding at least a portion of the first supply unit to communicate with the first supply unit such that the first cell supplied from the first supply unit is cultured in the culture medium; at least one second reservoir disposed at one side of the first reservoir and comprising a second supply unit that has an annular empty space with an opened top surface such that a second cell to be cultured and a culture medium are supplied; a second compartment comprising a second culture unit that communicates with the second supply unit and has a partially annular empty space by surrounding a portion of the first compartment at an interval such that the second cell supplied from the second supply unit is cultured in the culture medium; a first channel unit wherein a plurality of first microchannels communicating the first compartment and the second compartment are annularly arranged; a first communicating unit comprising a first communicating path communicating the at least one second reservoir and the second compartment; at least one third reservoir disposed at the other side of the first reservoir and comprising a third supply unit that has an annular empty space with an opened top surface such that a third cell to be cultured and a culture medium are supplied; a third compartment comprising a third culture unit that communicates with the third supply unit and has a partially annular empty space by surrounding a portion of the second compartment at an interval such that the third cell supplied from the third supply unit is cultured in the culture medium; a second channel unit wherein a plurality of second microchannels communicating the second compartment and the third compartment are annularly arranged; and a second communicating unit comprising a second communicating path communicating the at least one third reservoir and the third compartment.
