[PDF][PDF] Single-cell transcriptomic analysis of cardiac differentiation from human PSCs reveals HOPX-dependent cardiomyocyte maturation

CE Friedman, Q Nguyen, SW Lukowski, A Helfer… - Cell stem cell, 2018 - cell.com
Cardiac differentiation of human pluripotent stem cells (hPSCs) requires orchestration of
dynamic gene regulatory networks during stepwise fate transitions but often generates …

Biomaterializing the promise of cardiac tissue engineering

JE Pomeroy, A Helfer, N Bursac - Biotechnology advances, 2020 - Elsevier
During an average individual's lifespan, the human heart pumps nearly 200 million liters of
blood delivered by approximately 3 billion heartbeats. Therefore, it is not surprising that …
