As expected, the fluorescent cells (ZsGreen-ODC positive) from the three cancers mentioned above demonstrated features of stemness, including the ability to form tumours as mice xenotransplants and to undergo asymmetric cell division.
There are 3 types of transplants, depending on the sources from which the kidneys have been collected: cadaveric transplants (organs taken from a deceased person), living transplants (the organs can come from either a related or unrelated living person) and xenotransplants (research has been put into finding a possibility of transplanting organs from animals, but so far the risks involved are considered to be of great concern).
To prioritize genetic aberrations in AML for therapeutic targeting and to develop a pipeline for personalized nanomedicines I will i) establish a biobank of transplantable primary human AML xenotransplants, ii) fully characterize the genetic landscape of these leukemias, iii) establish the functional hierarchy of driver and passenger mutations in these human leukemia models, iv) develop highly efficient nanoparticle-siRNA formulations that allow in vivo delivery of siRNA to primary AML blasts, and v) design double specific siRNA-based nanomedicines for improved efficacy and tolerability.
One of the most important purposes of these new avantgarde tendencies is that of becoming tissue and organ banks for xenotransplants.

The study results suggest that human PD-L1 could be used as a novel therapeutic agent to enhance tolerance of xenotransplants and also supports the possibility of using human PD-L1 transgenic pigs as xenotransplant donors.
