We have made ground breaking discoveries even with ongoing insurmountable constraints.
Result1: Confirm Activation of Ferritin Reporter after Co-culture
Increased fluorescence intensity (20X) after co-culturing with CD19+ Toledo tumor cells
Figure 1: Fluorescence intensity measurement from flowcytometry (left) and con-focal microscope (right). Co-culture was performed with 2 different tumor cells: antigen CD19- K562 (as negative control) and antigen CD19+ Toledo.
Result2: Confirm Ferritin’s Function of Iron Storage Inside Cells
Cells can successfully store iron ions inside after co-culturing with CD19+ Toledo tumor cells
Figure 2: Prussian Blue staining results for different co-culture groups. Left to right: JurkatWT only, engineered Jurkatonly, engineered Jurkatwith CD19- K562 tumor cells, engineered Jurkatwith CD19+ Toledo tumor cells. Top to bottom: pure medium, medium with 200nm ferric solution, medium with 500nm ferric solution. FAC=ferric ammonium citrate
MRI in vivo using naturally produced contrast agent will supplant the necessity of 5 or 6 other procedures.
