Stem Cells vs Exosomes
Exosomes are not live stem cells
Exosomes are cell-derived signaling vesicles. They may be discussed in regenerative medicine but should not be described as stem cells.
Core difference
Two different things
Stem cells
Living cells with the ability to renew and differentiate. Quality depends on source, count, viability, sterility, markers and storage.
Exosomes
Cell-derived nanoparticles carrying biological signals. They are not alive and have different production, purity and safety requirements.
