Heart cells’ environment a potentially major factor in heart disease

By William Weir When it comes to heart disease, the health of the scaffold where cardiac cells grow may be a much bigger factor than previously believed. Stuart Campbell, associate professor of biomedical engineering & cellular and molecular physiology, led a team of researchers examined the effects of a diseased extracellular matrix (ECM) — the… Read More »

New Immune Cells Found in Mother’s Milk

It’s well-known that breastfed babies tend to be healthier than babies given a bottle filled with formula, especially in their first year of life, and the benefits are numerous. What’s more, the longer a baby is breastfed, the more far-reaching the health effects are throughout their lives. The developing field of stem cell biology is… Read More »

Ultrasound aligns living cells in bioprinted tissues

North Carolina State University researchers have developed a technique to improve the characteristics of engineered tissues by using ultrasound to align living cells during the biofabrication process. “We’ve reached the point where we are able to create medical products, such as knee implants, by printing living cells,” says Rohan Shirwaiker, corresponding author of a paper… Read More »

Artificial Embryos Made from Stem Cells Raise Ethical Issues

Stem cells (so-called “master cells”) are unique and important in the body because they can do almost anything, and scientists have only begun to discover their potential. That’s why researchers’ use of them has created controversy, attracting the attention of scientists, policymakers, and bioethicists across the globe. Stem cells can transform into any of the… Read More »
