We were granted a patent for “a composition for treatment of intractable neurological diseases and its manufacturing method”.

SAISEIKEN has developed an ultrasonic culture method and succeeded in producing a highly functional culture supernatant derived from deciduous tooth stem cells.

This new highly functional culture supernatant contains many physiologically active substances that are effective for nerve regeneration.
In fact, 20 AD (Alzheimer’s disease) patients showed clear therapeutic effects after 8 weeks of intranasal administration of the high-functioning culture supernatant.
