Kelly, a curious listener, ignited a quest into human regeneration after questioning if our tongues can regrow. Joined by Dr. Elly Tanaka, an expert on axolotls—the amphibians renowned for regrowing limbs—they explore why humans lag behind in regeneration. The conversation dives into the evolutionary origins of regenerative abilities, potential dormant genes in humans, and innovative lab-grown heart organoids. Kelly even showcases her new axolotl tattoo, symbolizing this fascinating journey into the limits and possibilities of bodily regeneration.
