MODIFIED CELL BY PUTTING MATERIAL INTO THE CELL WITHOUT USING DELIVERY VEHICLE

1 . A modified cell prepared by putting material into the cell through a process by using a bonding-less device which comprises:

i) a first passage on which the cell passes;

ii) a second passage on which said material passes and connected to the first passage at a position randomly selected between both ends of the first passage; and

iii) an apparatus which applies pressure difference or electric potential difference on the first passage and the second passage,

and the process comprises:

1) a step of flowing a fluid containing the cell through the first passage and flowing the material through the second passage; and

2) a step for putting the material into the cell flowing through a site where the second passage is connected to the first passage by applying electric potential difference and/or pressure difference on the second passage.

11 . A cell composition containing a modified cell prepared by putting material into the cell through a process by using a bonding-less device which comprises:

i) a first passage on which the cell passes;

ii) a second passage on which said material passes and connected to the first passage at a position randomly selected between both ends of the first passage; and

iii) an apparatus which applies pressure difference or electric potential difference on the first passage and the second passage,

and the process comprises:

1) a step of flowing a fluid containing the cell through the first passage and flowing the material through the second passage; and

2) a step for putting the material into the cell flowing through a site where the second passage is connected to the first passage by applying electric potential difference on the second passage.

12 . The cell composition according to claim 11 , wherein the composition comprise cell-culture medium.
