Organovo made faster than expected progress in validating its 3D liver assays, completing functional validation in late January rather than March and providing them to Key Opinion Leaders in April rather than planned for later. While revenue from the liver assays launching in December 2014 will not be seen until mid-2015, the opinions of these KOLs will have a major impact on the company's stock and the investment thesis for shareholders before then. Investing in speculative companies like Organovo should only make up part of one's portfolio alongside more stable dividend paying stocks.
