A new study finds key differences between established and new human embryonic stem cell lines.

Amander Clark, assistant professor of Molecular, Cell and Developmental Biology, and colleagues recently found that established human embryonic stem cell lines, including those approved for federal research funding, differ from newly derived human embryonic stem cell lines. This finding highlights the importance of continuing to derive new stem cell lines so that researchers can better understand the ability of these cells to make every cell in the human body.
