In-vitro model to study cell-cell interaction
There is a lack of experimental model to study the interactions of tumor versus normal cells. There are suggestions that certain genetic alterations, chemokines and growth factors has effect on tumor cell migrations. A new microfluidics technology enables to produce a 3D in vitro model with micromet...
