"In all the excitement over the new future for embryonic stem cell, it seems investors have forgotten about adult stem cell products," notes growth stock specialist Dave Dyer.

In his Dave Dyer's Newsletter, he explains, "In fact, there are adult stem cell products either already on the market or in late clinical trials. We view this as an excellent opportunity." Here, he looks at NuVasive (NASDAQ: NUVA).

"Stem cells can grow into any type of organ or tissue and the promise is that damaged organs may be repaired or even replaced with spare parts grown from stem cells. This amazing potential could revolutionize the life sciences.

"NuVasive is a rapidly growing company with unique technology for minimally-invasive back surgery; named Osteocel, it is a stem cell-based product used to help with bone grafts done as a part of spinal surgery.

"Stericycle (NASDAQ SRCL) is a near-monopoly in an essential but unglamorous area, making its an excellent investment in an uncertain economy," says growth stock expert Dave Dyer.

In his Dave Dyer's Newsletter, he states, "If you have something that is dangerous, contaminated, or nasty, and you want it to go away safely, you can rely on SRCL, the leader in medical waste."

"I first recommended the stock almost a year ago, but there is so much good news that I thought this would be a good time to recommend it again.

"And while the stock's 12.4% gain since last August is not spectacular, the S&P 500 is down 14.1% over the same time period -- so SRCL has outperformed the market by a wide margin.

"SRCL is North America's largest provider of medical waste services. In fact, if a major customer wants to contract with a single customer for nationwide services, SRCL is the only choice. Even if the market has not really bottomed out, this is an excellent stock to consider because its business is almost entirely immune to economic cycles.
