Heart Chambers From Stem Cells
Stem Cell Research

Stem cell creations are replacing research rodents at such a rapid pace that America’s white rats will be on strike before we know it.

Researchers at Ohio State University used stem cells to grow a fetal brain, an Italian researcher is experimenting with stem cell-assisted head transplants and researchers at Cal Berkeley have now grown heart chambers! These and other developments will eventually put lab rats and mice out to pasture, as human organs grown in labs are increasingly used for research.

The tiny heart chamber, .05 millimeters in diameter, was created by placing adult human skin cells in a petri dish, adding layers of oxygen plasma etchings, and scientifically coaxing the cells to form various heart cells until the tiny chambers were created in approximately 20 days.

A video of the minuscule, slowly beating heart chambers can be seen here, courtesy of “Nature Communications” Journal:

Berkeley Professor Kevin Healy conducted the research with Gladstone Institutes and co-wrote a study that can be read here:

According to Professor Healy’s press release, “This technology could help us quickly screen for drugs likely to generate cardiac birth defects, and guide decisions about which drugs are dangerous during pregnancy.”

To test the theory that these human heart chambers will assist in drug screening, the researchers developed some heart chambers with Thalidomide, that notorious drug once used to alleviate morning sickness in pregnant women. True to Thalidomide’s historically tragic effects, the drug “significantly damaged the cardiac micro chambers, generating chambers with smaller size, lower contractility and beat rates compared with controls.”
