All life on Earth relies, ultimately, on the delicate coordination of switches. During development, these switches turn genes on—or keep them off—at precise intervals, controlling the complex processes that guide the growth of the embryo, cell by cell, as it matures from a collection of stem cells into a living, breathing organism. If you control … Continue reading ‘STARS’ Help Scientists Control Genetic On/Off Switch

Finding the Sweet Spot: shifting metabolism keeps stem cells in suspended animation
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
