The present invention provides: a manufacturing metnod for microvesicles containing lentivirus R A having a transgenic product and/or a transgene, the method including a step in which cells are cultured after having a transgene introduced thereto using a lentivirus vector ：from wmch at least one structural protein gene has been deleted, and which contains a transgene under the control of a telomerase reverse transcriptase (TERT) gene promoter in the lentivirus genome sequence, and then microvesicles containing the lentivirus RNA having a transgenic product and/or transgene are released to the outside of the cell, and a step i n which the released microvesicles are collected； microvesicles obtained using said method； and uses for said microvesicles.
