Two stem cell stories in the news today bring to mind yesterday's interview on NPR's Fresh Air, in which veteran journalist Matthew Wald of the New York Times said of the decision to store spent nuclear waste in Yucca Mountain, NV:

Much has been written over the past few days about a spate of new papers by CIRM grantees showing significant differences between reprogrammed iPS cells and embryonic stem cells (see the San Diego Union Tribune, Discover, Technology Review) and CIRM grantee Paul Knoepfler
Many people in the stem cell community and at CIRM have been concerned about the growing trend of stem cell tourism -- people going overseas to receive unproven "stem cell" therapies. The term Stem Cells is in quotes here because in general these clinics are less than open about what, exactly, the therapy entails. One tourism destination in Costa Rica owned by an Arizona entrepreneur was just shut down by the country's Health Ministry. According to a story in Reuters the treatments cost between $5,000 and $30,000.

Two recent papers by CIRM grantees highlight the importance of understanding basic stem cell biology while developing new cures. Both have to do with chemical modifications to the DNA â called epigenetics.
One of the two papers shows that an epigenetic change in DNA, called methylation, changes dramatically as human embryonic stem cells mature into specific cell types; the other shows that even subtle DNA methylation differences alter the way a cell behaves.
