ProtoKinetix, Incorporated announced that after the conclusion of 4-years of extensive testing, evidence of fully functional retinal cells was conclusively achieved. In vivo tests demonstrated that transplantation of PPCs pre-treated with AAGP® (PKX-001) results in statistically significant improvements in both the visual behavioral (optokinetic tracking test) and functional analysis (electroretinogram test) responses as compared with PPCs without pre-treatment. Imaging data revealed that pre-treatment of PPCs with AAGP® also leads to a substantial enhancement of cell survival as determined at 3, 4.5 and 6 months after cell transplantation. At the 6-month time point, the AAGP®-treated cells acquired the ability to express retinal and synaptic proteins, confirming that AAGP® has no adverse effect on precursor cells™ maturation.
