They do not and never will even have the manufacturing capacity to even be ABLE to sell the product if it was in high demand.
That's simply not true and if it's your opinion it's not a very well-informed one. The $22 million financing they just announced, along with the expansion plans outlined in their investor presentation on pages 23-24 (http://www.fibrocellscience.com/investors/pdf/Fibrocell_Investor_Presentation-July-2011.pdf) are good resource for making an assumption about their future manufacturing projections. That's only within their existing facility in Exton, PA.
Additional partnerships or JVs, like the one they've announced in China will only further increase that manufacturing capability. You can read more about it here: http://www.fibrocellscience.com/about_us/jv_china.htm
