Exosome treatment improves recovery from heart attacks in a preclinical study

Research in pigs shows that using the exosomes naturally produced from a mix of heart muscle, endothelial and smooth muscle cells — all derived from human induced pluripotent stem cells — yields regenerative benefits equivalent to the injected human induced pluripotent stem cell-cardiac cells.

‘Primitive’ Stem Cells Shown to Regenerate Blood Vessels in The Eye

Johns Hopkins Medicine scientists say they have successfully turned back the biological hands of time, coaxing adult human cells in the laboratory to revert to a primitive state, and unlocking their potential to replace and repair damage to blood vessels in the retina caused by diabetes. The findings from this experimental study, they say, advance regenerative medicine techniques aimed at reversing the course of diabetic retinopathy and other blinding eye diseases.
