Comprehensive Routing Architecture for Extracellular Vesicle Targeting, Tissue Addressability, Organ Navigation, and Precision Communication Biology
Program Code: HEMOREGEN-COMM-002
Division: HEMOREGEN-COMM
Parent Program: HEMOREGEN-721
Former Code: SCF-VIRA-EVCM-0002
Classification: EV Routing and Navigation Platform
Status: Master Foundational Atlas v1.0
EXECUTIVE SUMMARY
The Blood EV Address Code Atlas establishes the master routing architecture governing how extracellular vesicles identify, navigate toward, dock with, and deliver cargo to specific biological targets.
Within PROJECT HEMOREGEN-721, EV addressability is considered the fundamental communication layer that determines whether biological information reaches the correct recipient cell, tissue, organ, or physiological network.
This atlas establishes:
- EV routing codes
- Tissue-specific targeting signatures
- Organotropic navigation mechanisms
- Address fidelity metrics
- Communication topology
- Synthetic EV targeting engineering frameworks
SECTION I — EV ADDRESSABILITY HYPOTHESIS
Core Principle
Every EV contains two independent systems:
Cargo System
Determines:
“What message is carried?”
Address System
Determines:
“Where is the message delivered?”
Address Equation

Addressability Function:
AF = SAC × RAC × GAC × MAC × TAC
