Stem-Cell-Free Regenerative Medicine: New Advances
For good reason, stem cells and regenerative medicine are often mentioned in the same sentence.
Stem cells have successfully reversed the brain damage caused by Parkinson’s, repaired spinal cords that were severed, or repaired damaged tissue due to diabetes, strokes, blood cancers or heart disease. The discovery of induced stem cells (iPSCs), which can reverse skin and other tissues into a stem-cell-like state, has led to the adaptation of the cells into bio-inks for 3D printing new organs.
But stem cells are difficult to obtain, manufacture and grow. They are at risk of cancer if they are not made from a patient’s cells, which would increase production costs.
