In this January episode of @MayoClinic's Tomorrow’s Cure podcast, host @CathyWurzer explores how 3D bioprinting is advancing human‑relevant skin research.

Guests @drwyles_derm (@MayoRegMed) and Adam Feinberg, Ph.D. (@cmu_bme & @cmu_mse at @CMUEngineering), discuss building living skin models from human cells and biologic materials to study aging, wound healing, and disease.

Dr. Wyles introduces the concept of “skin span,” emphasizing the importance of modeling how skin structure and function change over time and across conditions. Dr. Feinberg describes bioprinting collagen to mimic native human tissue and improve predictive value in research.

Both emphasize how these models support the shift away from animal testing:

“Dr. Feinberg adds that moving away from animal testing is a growing priority, and engineered human tissue models may improve prediction because animal physiology differs from humans.”

This work can lead to reliable preclinical testing, a better understanding of chronic wounds, and improve equity in how science is conducted and who it benefits from it.

Across infectious disease research, experiments on animals fail to capture human‑specific immunity, tissue biology, & host–pathogen interactions.

Check out these recent papers describing how human‑based technologies can deliver predictive insights into disease mechanisms, immune responses, & therapeutic efficacy (good reading for #NPHW!):

Progress in treating nervous system injuries has been historically limited by a lack of human‑relevant models.

Neural repair experiments on animals "fall short in replicating human-specific features such as long axonal architecture, species-specific gene regulation, and cellular diversity, all of which are critical for understanding neural repair in humans."

In this new review, @RutgersBioSci researchers highlight how human induced pluripotent stem cell (iPSC)–based models are changing what's possible for this field.
https://t.co/8Ru2J4YESN

From 2D cultures and 3D organoids to microengineered injury platforms and patient‑specific cell types, these models are revealing key regulators of neurite growth, clarifying how disease‑linked mutations disrupt axonal integrity, and accelerating the discovery of neuroprotective and pro‑regenerative compounds.

@manasiagrawal1, Meghal Desai, Shruti Ghumra, Yashashree Bhorkar, and @SahooLab discuss how iPSC‑derived neurons, glia, Schwann cells, and neuromuscular junctions are advancing our understanding of remyelination, axon‑glia interactions, and circuit‑level repair—areas where translation from experiments on animals has repeatedly fallen short.

Investing in human‑relevant platforms offers the best chance of developing therapies that restore function after nervous system injury and for furthering the field of regenerative neuroscience.

In response to criticism of @CDCgov's decision to end its in-house experiments on non-human primates, Lynn Taylor, MD (@LMTaylor79), Etai Bally, and Zach Burns, DO penned a powerful letter outlining the many reasons the agency's choice was a good one.

✅ Myriad studies show that experiments on non-human primates fail to predict human responses.
✅ Scientific techniques exist that are more relevant to human health.
✅ "Nonhuman primates are highly intelligent, sensitive, social beings. Using them in research is cruel and sadistic, inflicting avoidable pain, fear and suffering."
✅ The use of monkeys in laboratories and the international monkey trade that supplies them poses zoonotic disease risks that endanger public health.
✅ Most of the world's primates are at risk of extinction.
✅ Past contribution does not entail present necessity.
