8 Scientists discover human heart muscle can regenerate after heart attack¶
Researchers at Australian institutions demonstrated for the first time that human heart muscle cells can regenerate after a heart attack, challenging decades of assumption that cardiac tissue loss is permanent. While a single heart attack can destroy up to one-third of heart cells and scarring limits regeneration, the finding opens possibilities for therapies to amplify the heart's natural repair mechanisms.
- First demonstration of cardiac regeneration in human heart tissue, not just mice
- Single heart attack can destroy up to one-third of heart cells
- Findings published in Circulation Research
- Natural regenerative response exists but insufficient to replace all damaged muscle

7.5 UCLA develops cancer-fighting T cells from cord blood for solid tumors¶
UCLA researchers engineered T cells from cord blood stem cells that attacked solid tumors in mice while avoiding graft-versus-host disease. These AlloESO-T cells use TCR therapy to recognize cancer proteins and can be manufactured in frozen batches, addressing cost and production-time barriers that plague current personalized T-cell therapies.
- AlloESO-T cells successfully controlled ovarian cancer and melanoma in mice with single dose
- TCR therapy detects internal protein fragments, broader than CAR T-cell approach
- Current personalized T-cell therapy costs six figures and takes weeks to produce
- Cord blood cells enable pre-manufactured frozen batches for multiple patients
- Published in Cell Reports Medicine
