Abstract: A method for the induction of callus cells capable of producing taxanes from explant tissue by partially submerging the explant tissue in a liquid culture medium on a membrane raft, resulting in callus formation. The induction of callus cells by this method provides direct transfer of the cells formed to a liquid medium for a suspension cell culture preparation of taxanes. Thus, there is no need of a separate growth or proliferation step in the method of this invention. Furthermore, callus cells can be produced by the method; and also disclosed is a method for the use of the callus cells so produced in a suspension cell culture preparation for taxanes.
