NEW YORK, June 28, 2010 — NeoStem, Inc. (“NeoStem” or the “Company”) an international biopharmaceutical company with operations in the U.S. and China, announced that it has been added to the broad-market Russell 3000 Index with Russell Investments’ reconstitution of its comprehensive set of U.S. and global equity indexes effective June 25, according to a list of additions posted on http://www.russell.com .

“Joining the Russell indices represents an important milestone in NeoStem’s history. As part of the Russell indices, we see the opportunity to increase the Company’s visibility within the investment community and further diversify our shareholder base,” said Robin Smith, NeoStem’s Chairman and CEO. “Our selection to join the indexes reflects the increase in the Company’s market capitalization over the past year and the positive momentum as we advance our adult stem cell therapies in China and the acquisition of a profitable and growing majority-owned pharmaceutical subsidiary, Suzhou Erye.”

Annual reconstitution of Russell’s U.S. indexes captures the 3,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization. Membership in the Russell 3000, which remains in place for one year, means automatic inclusion in the large-cap Russell 1000 Index or small-cap Russell 2000 Index as well as the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes.

The Russell 3000 also serves as the U.S. component to the Russell Global Index, launched in 2007.

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. An industry-leading $3.9 trillion in assets currently are benchmarked to them. These investment tools originated from Russell’s multi-manager investment business in the early 1980s when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers.
