Claim 15:
16. The microfluidic cell culture chip according to claim 14, wherein said upper orifice of said at least one tubular-shaped duct leads to one single perforation of said support, and wherein an entirety of said perforation of said support faces said upper orifice of said at least one tubular-shaped duct,
when the value of the lower diameter d2 of said perforation is equal to the value of the diameter d4 of said upper orifice of said at least one tubular-shaped duct, and the second axis, passing through the centre of a lower section of the perforation and perpendicular to said support, and the third axis, passing through the centre of said upper orifice of said at least one tubular-shaped duct and perpendicular to said support, are coincided with each other, or
when the value of the lower diameter d2 of said perforation is less than the value of the diameter d4 of said upper orifice of said at least one tubular-shaped duct, and the second axis, passing through the centre of said lower section of the perforation and perpendicular to said support, and the third axis, passing through the centre of said upper orifice of said at least one tubular-shaped duct and perpendicular to said support, are distinct from one another by a distance less than or equal to a value obtained by a formula: (value of d4−value of d2)/2.
