Just yesterday, one of those Fools, All-Star zzlangerhans, succinctly summed up the bear case for our community:

[CEO Zami Aberman] predictably took advantage of his anecdotal claims that PLX cells were responsible for successful bone marrow transplantation in three instances, although there has been no clinical trial in which PLX cells were utilized for this purpose. I don't have much sympathy for those who bought into the dilutive financing at [$4 per share], since they should have known the share price is unlikely to see that level again for a while until dilution becomes necessary again. The company now has to slog through enrollment of the phase II trial of PLX cells in intermittent claudication and it is unclear if a single patient has yet been treated. I see a descent below [$3 per share] if not further as Aberman lowers the company's profile for the rest of the year.
