Researchers are now able to use induced pluripotent stem cells (iPSC) to form a model of human adult-like cardiac muscle by introducing electric and mechanical stimulation at an early stage. Since this muscle is similar to the adult heart, it could serve as a better model for testing the effects of drugs and toxic substances than current tissue-engineered heart models.

Researchers funded by NIH have developed an imaging method that reveals a much more diverse and flexible DNA-protein chromatin chain than previously thought. The result suggests a nimbler structure to regulate gene expression, and provide a mechanism for chemical modifications of DNA to be maintained as cells divide.

A team of scientists funded by the National Institutes of Health has developed a new tool to monitor under a microscope how cells attach to one another. Studying adhesion events can help researchers understand how tissues grow, how diseases spread, and how stem cells differentiate into more specific cell types.

Scientists funded by NIH have developed a new way to identify the state and fate of individual stem cells earlier than previously possible. Stem cells are undifferentiated, serving as building blocks for the various tissues and organs of the body. Understanding a stem cell’s fate—the type of cell it will eventually become—and how far along it is in that process can help scientists better manipulate cells for therapies.
