CHICAGO — Northwestern Medicine researchers for the first time have transformed a human embryonic stem cell into a critical type of neuron that dies early in Alzheimer’s disease and is a major cause of memory loss.

BOSTON (Nov. 23, 2010) — Breast cancer stem cells (CSCs), the aggressive cells thought to be resistant to current anti-cancer therapies and which promote metastasis, are stimulated by estrogen via a pathway that mirrors normal stem cell developmen…
ANN ARBOR, Mich—University of Michigan researchers have determined that most types of melanoma cells can form malignant tumors, providing new evidence that the deadliest form of skin cancer does not conform to the increasingly popular cancer st…
The Stanford University School of Medicine announced on Dec. 10 plans to form an Institute for Cancer/Stem Cell Biology and Medicine. This multidisciplinary institute will study both stem cell biology and cancer biology, and will attempt to apply knowledge learned from stem cell biology to new treatments for cancer.
Q: Is Stanford planning on cloning human embryos?
A: No. The new institute will study adult stem cell lines generated from individuals with specific diseases such as cancer or neurodegenerative disorders. The institute will also investigate two different ways of generating new embryonic stem cell lines ? initially in mice. This may be extended to human cell lines if the techniques prove useful.
This weekend I sank my teeth into some delicious beef ribs. But researchers at the Forsyth Institute say they’ve done one better ? they’ve sunk pork teeth into rat guts. The experiment involved taking seeded cells from immature teeth of six-month-old pigs and placing them in the intestines of rats (who no doubt were thrilled at the addition). Within 30 weeks, small tooth crowns made of enamel and dentin had formed. Within five years, the Forsythe team says, they hope to be able to harvest teeth of specific size and shape, and five years after that to regrow human teeth.
