I Sing the Bioelectric: Long-Distance Electrical Signals Guide Cell Growth and Repair

Genes turn on, and genes turn off. Again and again, the genes that together comprise the human genome receive electrical signals that can direct when they should be active—and when they should be dormant. This intricate pattern of signals is a part of what guides an embryonic stem cell to grow and mature into any … Continue reading I Sing the Bioelectric: Long-Distance Electrical Signals Guide Cell Growth and Repair

The future is bright for a stem cell: it has the potential to become almost anything. This potential is one of its two defining characteristics. The second is that it can create copies of itself over and over again. This second characteristic, known as the ability to self-renew, is of particular importance to researchers. After … Continue reading Finding the Sweet Spot: shifting metabolism keeps stem cells in suspended animation
