New scalable method to advance maturation of human pluripotent stem cell-derived cardiomyocytes

A Mount Sinai-led team has developed a reproducible and scalable method to advance maturation of human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs)-;cells that support heart muscle contraction, generated in the lab from human stem cell lines-;which researchers say will improve approaches for disease modeling, regenerative therapies, and drug testing.

New method helps distinguish bacterial DNA from human and other non-bacterial cells

For decades, a small group of cutting-edge medical researchers have been studying a biochemical, DNA tagging system, which switches genes on or off. Many have studied it in bacteria and now some have seen signs of it in, plants, flies, and even human brain tumors.
