Bioengineers from the University of California, Berkeley, have utilized adult stem cells to create a network of pulsating heart cells encased in a silicon chip, effectively modeling cardiac tissue. To capture the dynamic structure and function of the heart, the scientists loaded the stem cells into a layered, 3-D scaffold to mimic the geometry of the organ and included channels on either side of the chip to act as blood vessels, thus replicating the organ’s natural exposure to nutrients and therapies.

In a newly published phase II clinical trial from the Asan Medical Center in Seoul, Korea, researchers observed full recovery from fistulas [abnormal connections between organs caused by the inflammation] in 75% of patients suffering from Crohn’s disease upon the injection of autologous [the patient’s own] stem cells. MSCs have the ability to regulate the patient’s immune system to reduce inflammation, resulting in the complete closure of the fistulas without recurrence.

Recently published research from Monash University has demonstrated the effect of adult stem cells and the protein serelaxin in reversing the scarring on kidneys that typically lead to end-stage renal disease. While adult stem cells are moderately successful on their own, the scar reduction of serelaxin provided a better environment for them to help the kidney repair itself, providing significant protection from future damage.
