For instance it has been clearly demonstrated that non-embryonic stem cells (non-ESCs)which include umbilical-cord cells, placental derived cells, as well as adult stem cells found in places such as blood, bone marrow, skin and breastdo not cause cancer in humans. Also, if non-ESCs are obtained from the patient or from a family member donor with a matching tissue type, the risk of immune rejection of the non-ESCs can be virtually eliminated.
By contrast, research has shown that embryonic stem cells (ESCs), which are derived from embryos that are destroyed in the process, have great potential to produce cancer in humans...

It's part of a pattern that has shown itself in the last days of the campaign. Mr. Crist said he opposed state intervention in the Terri Schiavo case, but Michael Schiavo's attorney corrected the record last week by noting that Mr. Crist's office had argued in favor of intervention three years ago.
