Induced pluripotent stem cells. Nobel Prize 2012.

"When I saw the embryonic stem cell-like colonies, I was so excited I couldn't sleep."

Biography

Shinya Yamanaka revolutionized stem cell research by discovering how to reprogram adult cells into induced pluripotent stem cells (iPSCs) using just four transcription factors. His groundbreaking 2006 work opened new possibilities for regenerative medicine while avoiding the ethical concerns of embryonic stem cells, earning him the Nobel Prize in Physiology or Medicine in 2012.

Key Facts

Discovered that just four genes (Oct4, Sox2, Klf4, c-Myc) can reprogram adult cells back to an embryonic-like state
Originally trained as an orthopedic surgeon before switching to basic research after struggling with clinical work
His iPSC discovery was initially met with skepticism until successfully replicated by other laboratories
Established the Center for iPS Cell Research and Application at Kyoto University in 2010
Won the Nobel Prize at age 50, making him one of the youngest recipients in recent decades
