Acceleron doubles its space in Cambridge

Acceleron Pharma Inc. said today that it has doubled its space in Cambridge to 75,000 square feet as it looks to grow its head count by about 40 percent by the end of the year.

The privately held biopharmaceutical company is developing novel therapeutics that modulate the growth of tissues, including bone and muscle.

Acceleron said it plans to build its second protein manufacturing facility at the additional 37,500 square feet of space it has leased; as a result of the new lease, the company will fully occupy two buildings in Central Square.

Acceleron ended 2007 with 85 employees, and it expects to end this year with 120 to 125 employees, a company spokesman said.
