Nieuwe hype: exosomes


"The word of the year for 2019 in the hair loss world has got to be “Exosomes”. Another name for exosomes is extracellular vesicles (EVs). They are usually derived from mesenchymal stem cells.
Exosomes contain no DNA or nucleus, and are around 1000 times smaller in size compared to regular cells. More specifically, exosomes are tiny nanoparticles (50-150 nanometers) that are involved in cell-to-cell communication and intercellular signaling. They are secreted by most cell types in the body, and contain both messenger RNA and microRNA (miRNA).
Exosomes were first discovered around 35 years ago.

They have been studied extensively for the past decade in the regenerative medicine field for therapeutic applications.


Exosomes are known to activate several signaling pathways that are important in wound healing, tissue regeneration and bone fracture repair. This phenomenon is called paracrine signaling. Due to their lack of DNA, exosomes from stromal cells cannot become malignant or cancerous."
