Buy and HoldAs a long term holder, I bought back at .32-.40, I'm in it for the long run. I recently loaded up again at .10.
The potential for these therapies is mind boggling. They seem to work. Management is good and has been hampered by the unbelievable slow approval process and the perception that stem cell research (even on your own cell stems) is unethical.
People with Parkinson's, MS, etc. should be outraged that there is no fast track for clinical trials for these therapies which have been proven safe.
Finally there is some interest in the investor community, but there is still speculation of a round of dilutive private placement which is holding the price down. I believe that it is still trading below any dilutive price... so load up and hold.
