🎙 The Joe Rogan Experience

JRE JUNE 2021 · DAVID SINCLAIR, HARVARD · SPOTIFY
Sinclair walks Rogan through his landmark research using Yamanaka factors (OSK) to restore vision in old mice — and what it means for human aging reversal. Available exclusively on Spotify.
JRE SEPT 2019 · DAVID SINCLAIR, HARVARD · SPOTIFY
The episode that introduced millions to reprogramming factors as an anti-aging tool. Sinclair explains how Yamanaka factors repair eyesight and what a biological age reset could look like.

🎙 Lex Fridman Podcast

Lex Fridman Sinclair
LEX FRIDMAN JUNE 2021 · DAVID SINCLAIR, HARVARD
At 43:50, Sinclair and Fridman discuss the "genetic reset switch that reverses aging" — the OSK subset of Yamanaka factors and how they reset the age of tissues without erasing cellular identity.

🎙 Huberman Lab

Huberman Lab #52
HUBERMAN LAB DEC 2021 · DAVID SINCLAIR, HARVARD
One of Huberman's most-watched episodes. Sinclair covers the full science of epigenetic reprogramming and Yamanaka factors as the biological reset switch — with actionable protocols for slowing aging today.
Huberman Pasca
HUBERMAN LAB 2025 · DR. SERGIU PAȘCA, STANFORD
Stanford neuroscientist Pașca and Huberman discuss stem cell models with a dedicated segment on Yamanaka factors and their role in building human brain organoids for disease research.

🎙 The Peter Attia Drive

Peter Attia #70
PETER ATTIA 2019 · DAVID SINCLAIR, HARVARD
Perhaps the most technically deep podcast discussion of Yamanaka factors available — Attia and Sinclair go deep on the full mechanism of cellular reprogramming, including viability in humans.

🎙 The Diary of a CEO

Diary of a CEO Rhonda Patrick
DIARY OF A CEO JULY 2025 · DR. RHONDA PATRICK
Dr. Rhonda Patrick gives Steven Bartlett a clear, accessible explanation of Yamanaka factors and partial reprogramming — how pulsing four proteins onto an aged cell can restore youthful function without erasing cellular identity.

What Are Yamanaka Factors?

In 2006, a Japanese scientist named Shinya Yamanaka changed biology forever. He discovered that four ordinary proteins could rewind the clock on a fully mature cell — turning it back into a stem cell capable of becoming any tissue in the body.

The Four Factors

The "Yamanaka factors" are a set of four transcription factors — proteins that regulate gene expression. Together, they can reprogram differentiated adult cells into induced pluripotent stem cells (iPSCs):

Factor I
Oct3/4

A master regulator of pluripotency. Activates stem-cell genes and suppresses differentiation. Central to the reprogramming cascade.

Factor II
Sox2

Works in tandem with Oct4 to maintain the pluripotent state. Also plays roles in neural development and brain plasticity.

Factor III
Klf4

Balances cell proliferation and differentiation. Helps reset the epigenome to its embryonic state during reprogramming.

Factor IV
c-Myc

A powerful growth-promoting oncogene. Boosts reprogramming efficiency but poses tumor risk — a key safety challenge for therapies.

Why It Matters

The original discovery earned Yamanaka the 2012 Nobel Prize in Physiology or Medicine. Researchers discovered that partial reprogramming can reset epigenetic aging marks while preserving the cell's identity — potentially enabling true biological age reversal in living tissue.
