Antineo : Diffuse Large B Cells Lymphoma tumour model – Toledo
-
Toledo cells
Human Toledo cells were isolated from the peripheral blood of a patient with non-hogkin’s DLBC lymphoma.
-
Tumour growth in vivo
The cells were collected from a tissue culture flask and injected subcutaneously in the right flank of SCID-CB17 mice. The resulting tumours were monitored by measuring two diameters with calipers, and extrapolating the volume to a sphere. The mice bearing Toledo tumours can be treated by intra-peritoneal, intra-venous, intra-tumoral or subcutaneous injection of the compounds. Per os administration is also possible.
