Medical Definition of Feeder layer
1.
| In order to culture some cells, particularly at low or clonal density, it is necessary to use a layer of less fastidious cells to condition the medium.
Often the cells of the feeder layer are irradiated or otherwise treated so that they will not proliferate. In some cases the feeder layer may be producing growth factors or cytokines.
