Some Stem Cell companies worth looking at

Well here is a good article about some stem cell companies out there. ViaCell (VIAC) seems like an interesting company because it has a nice side business in storing stem cells for parents. This business should keep them decently flush with cash so they don't have to rely of tapping the equity and debt markets so much. Seems like their bone marrow drug is quite a ways off though since it doens't mention it going into the FDA approval process at all.
