- Bubenik father-son team discovered trophic memory in deer antlers: injury at a specific point leads to ectopic tine regeneration in subsequent years.
- Deer antlers demonstrate adult mammal regeneration, growing bone and tissue rapidly, challenging notions of limited mammalian regenerative capacity.
- Trophic memory involves cells retaining information about past injuries, influencing future growth patterns even after antler shedding and regeneration.
- Planarian flatworms were used as a model to study morphogenetic memory, showing persistent two-headed regeneration after bioelectric pattern alterations.
- Bioelectric circuits store anatomical pattern memories in planaria, with voltage-sensitive dyes visualizing these encoded future regeneration plans.
- Research reveals that physiological experiences can rewrite target morphologies, impacting regenerative outcomes and suggesting unconventional inheritance mechanisms.
- Axolotl limb regeneration studies indicate potential fatigue or memory-based cessation after multiple amputations, with underlying causes still under investigation.
- The work underscores the interplay between genetic hardware and reprogrammable physiological software in cellular collectives, with implications for regenerative medicine.
