New Progress in Stem-Cell-Free Regenerative Medicine

Posted by in categories: 3D printing, biotech/medical, life extension, neuroscience

Regenerative medicine and stem cells are often uttered within the same breath, for good reason.

In animal models, stem cells have reliably reversed brain damage from Parkinson’s disease, repaired severed spinal cords, or restored damaged tissue from diabetes, stroke, blood cancers, heart disease, or aging-related tissue damage. With the discovery of induced pluripotent stem cells (iPSCs), in which skin and other tissue can be reversed into a stem cell-like state, the cells have further been adapted into bio-ink for 3D printing brand new organs.

Yet stem cells are hard to procure, manufacture, and grow. And unless they’re made from the patient’s own cell supply—massively upping production costs—they’re at risk of immune rejection or turning cancerous inside their new hosts.
