Visualizing DNA Labels in Cells and Tissues

Lori Dajose
A new bioengineering technique uses imaging to enable readout of the DNA barcodes of individual cells directly within tissues. This will allow researchers to combine information about the history of the cells, their present state, and their spatial position.

Coming to a Head: Insights from a Vampire of the Deep

Alison Koontz
Vertebrates, from fish to humans, have a backbone and a large head that includes jaws for efficient eating. By studying primitive jawless vertebrates, Caltech scientists show that gradual, progressive alterations to a cell type called the neural crest added new features, producing an ever-improving head.

Mending Broken Hearts with Neural Crest Cells

Lori Dajose
New research shows that certain muscle cells that originate from the embryonic hindbrain contribute to heart muscle and can revert back to a stem-cell state to repair damage in zebrafish hearts.
