What is a recent law concerning stem cells?

I need to find a recent law (federal or state) that was passed concerning stem cells for a report. Does anyone know where I can find this information because I've looked in various places and was unable to find a recent law within the last 2 years that was passed.

Michigan just passed a proposition for Stem Cell Research. Proposal 2.

Knieriem v. Group Health Plan, Inc.

Siade had an employer-sponsored health care plan provided by Group Health Plan, Inc (GHP). The plan was governed by ERISA. GHP issued the health insurance policy for the plan. In 2001, Siade was diagnosed with non-Hodgkin's lymphoma and sought GHP's pre-approval for an allogeneic stem cell transplant. GHP denied coverage on the basis the procedure was "investigational and unproven" and therefore excluded under the plan's policy."
