PS+ Exosomes World-Patent: “Exosome-specific biomarkers can help distinguish the nature of the type of cancer… Some exemplary exosome biomarkers can be found above in Table 1”. I would think Dr. Schroit & Team are working on the “can help distinguish” part as we speak.

ABSTRACT:
“Disclosed are methods of identifying tumor-derived exosomes as an early cancer diagnostic, as well as for staging, assessing progression, and assessing therapy of cancer.”

EXCERPT from SUMMARY:
“. . .The method may further comprise diagnosing the subject from which the sample was obtained as having cancer. The method may further comprise staging the cancer or classifying the cancer type in the subject from which the sample was obtained. The method may further comprise performing steps (a)-(c) a 2nd time, and comparing the results from the 1st & 2nd times, thereby assessing cancer progression or regression. The method may further comprise performing steps (a)-(c) a 2nd time, wherein the subject has received a cancer therapy after the 1st performance of steps (a)-(c) and before the 2nd performance of steps (a)-(c), and comparing the results from the 1st & 2nd times, thereby assessing the efficacy of cancer therapy. The method may further comprise treating the subject with a cancer therapy. . .
In addition to PS, exosomes exhibit a number of unique & non-unique markers. Some of the exosome-specific markers include biomarkers that can help distinguish the nature of the type of cancer from which the exosome originated. Some exemplary exosome biomarkers can be found above in Table 1. Global exosome biomarkers that can be detected with appropriately labeled agents include cd9, cd63, cd81, ALIX, HSP70, TSG101, duramycin, and heparin.”
