This invention designates that high transfer talent & the high infiltration talent acquisition model of the breast cancer-related cell are produced as purpose. This invention being the cell which is derived from the MCF7 cell, offers the MCF7 origin cell which possesses significantly high infiltration talent or transfer talent by comparison with the MCF7 cell. To be able by collecting the MCF7 cell which acquires basilar membrane manufacturing things such as or the similar thing passing talent matorigeru and the like it is possible the MCF7 origin cell of this invention.本発明は、乳癌関連細胞の高転移能・高浸潤能獲得モデルを作製することを目的とする。本発明は、MCF7細胞に由来する細胞であって、MCF7細胞に比較して有意に高い浸潤能または転移能を有するMCF7由来細胞を提供する。本発明のMCF7由来細胞は、マトリゲル等の基底膜調製物又はその類似物通過能を獲得したMCF7細胞を回収することによって得ることができる。
