A process using human stem cells can generate the cells that cover the external surface of a human heart -- epicardium cells -- according to a multidisciplinary team of researchers. Read more at Penn State News.
Proteins are the workhorse molecules of life. Among their many jobs, they carry oxygen, build tissue, copy DNA for the next generation, and coordinate events within and between cells. Now scientists have developed a method to control proteins inside live cells with the flick of a switch, giving researchers an unprecedented tool for pinpointing the causes of disease using the simplest of tools: light.

Scientists have used pluripotent stem cells to generate human stomach tissues in a Petri dish that produce acid and digestive enzymes. They grew tissues from the stomach's corpus/fundus region. The study comes two years after the same team generated the stomach's hormone-producing region (the antrum). The discovery means investigators now can grow both parts of the human stomach to study disease. Read more at Cincinnati Children's Hospital News.
Biomedical engineers have created a smart, targeted drug delivery system using immune cells to attack cancers. Read more from the Penn State Materials Research Institute.
Researchers have had initial success in mice using nanodiscs to deliver a customized therapeutic vaccine for the treatment of colon and melanoma cancer tumors. Read more at Michigan News.
Researchers have invented a transistor-like threshold sensor that can illuminate cancer tissue, helping surgeons more accurately distinguish cancerous from normal tissue. Read more and watch the video at UT Southwestern News.
