As someone in the biotech business, mainly start-up stage microcaps. I have seen this before. The insiders alwasy buy up all they can on open market. In time we will see a major anouncement from their clinical trials, and also on the hepa cells research from the tests done on the cells on the international space station.
Even with out the hepamate, those porcine cells are worth billions. The patent on them are still owned by Alliqua. I imagine some science anouncement on them in the future.
Frost also knows that cell line has promise, but we will see.
But in all things, one never knows one way or another, just my speculation.
