Aging Makes Retinal Regeneration Harder, Even When Cells Are Reprogrammed
Older mouse retinas produced fewer neurons after glial-cell reprogramming. Anti-inflammatory treatment helped partly, highlighting a barrier for regenerative medicine.
Engineered Cell Vesicles Improve Heart Repair in Rats
A cell-free approach improved cardiac function after experimental heart attack, but manufacturing and human translation remain major hurdles.
