The state awarded another $10 million in stem-cell research grants Tuesday, but not a single private company benefited.

Like the $80 million awarded in the previous seven years, most of the money this year went to the University of Connecticut Health Center or Yale University.

The Jackson Laboratory for Genomic Medicine, already the recipient of $291 million in taxpayer largess, secured $1.1 million from this batch of stem-cell research funding.

In the history taxpayer funding of stem-cell research in Connecticut, only two private companies received grants totaling $2.4 million out of about $90 million, or less than 3 percent.
