Researchers at Nagoya University in Japan successfully transplanted pituitary tissue derived from human stem cells into a primate that had its pituitary gland surgically removed, resulting in restored hormone signaling and increased cortisol levels. The team demonstrated that this transplantation technique also worked effectively in mice over extended periods. This represents the first successful transplant of lab-grown human pituitary tissue into a non-human primate.


This breakthrough could lead to new treatments for patients with pituitary disorders or hypopituitarism, who currently require lifelong hormone replacement therapy. The successful primate model brings this regenerative approach closer to potential human clinical applications for restoring natural hormone production.


Researchers in Japan have transplanted pituitary tissue grown from human stem cells into a primate whose pituitary gland had been surgically removed, successfully restoring critical hormone signals. Led by researchers from Nagoya University in Japan, the team showed that the same method worked in mice over a longer period.
