Claim 7:
8. The microfluidic cell culture chip according to claim 7, wherein
said at least one perforation of the support has
a circular-shaped section at the upper face of the support, which corresponds to an upper section of the at least one perforation, having a diameter d1, which corresponds to an upper diameter d1 of the at least one perforation and a first axis passing through the centre of said upper section of the at least one perforation and perpendicular to said support, and
a circular-shaped section at the lower face of the support, which corresponds to a lower section of the at least one perforation, having a diameter d2, which corresponds to a lower diameter d2 of the at least one perforation and a second axis passing through the centre of said lower section of the at least one perforation and perpendicular to said support,

wherein said first axis coincides with said second axis, the diameter d1 being a value greater than or equal to 10 μm and less than or equal to 500 μm, and the diameter d2 being a value greater than or equal to 10 μm and less than or equal to 500 μm,
wherein the value of the diameter d2 is greater than or equal to the value of the diameter d1,
wherein said circular base of said at least one protuberance has a diameter d3, said diameter d3 of the circular base of the at least one protuberance being a value greater than or equal to 10 μm and less than or equal to 500 μm, and
wherein said at least one protuberance has a height of 1 to 600 μm.
