Parabiosis Concept and Historical Context
🔬 The concept of youthful rejuvenation dates back to ancient Greece and was popularized in 19th-century European folklore.
🐭 This fascination led a French scientist in the mid-1800s to develop parabiosis, the surgical suturing of two animals (like mice) to create a shared circulatory system.

Regenerative Therapy Model (ReGina V's Model)
🧬 The modern adaptation replaces physical suturing with co-culturing young cells with aged cells to restore the immune system.
🔗 This process utilizes a transwell system—a two-chamber setup separated by a filter containing 400 nanometer nanopores.
🦠 The small pores prevent cell migration but allow beneficial factors like exosomes, microRNAs, and proteins from the young cells to pass through and restore the aged cells.

Therapeutic Application and Safety
⏳ The co-culturing process takes seven days before the aged cells are removed.
🛡️ The final therapy administered to the patient uses their own cells (autologous therapy), ensuring no risk of contamination from the young donor cells.

Key Points & Insights
➡️ The modern rejuvenation method focuses on paracrine signaling (exchange of small molecules) rather than direct circulatory connection.
➡️ The use of a transwell filter (400 nm pores) is crucial to ensure the final product is autologous (patient's own cells).
➡️ Key rejuvenating agents transferred from young to aged cells are exosomes, microRNAs, and proteins.
