1.   Besides the slow pace of commercialization, tissue engineering faces many technical hurdles.

2.   A future goal of tissue engineering, he said, would be to create a lab-engineered organ substitute to meet the need of patients seeking transplants.

3.   Along with the clinical success has come more evidence of the market potential for tissue engineering.

4.   But now, the company is aggressively entering the fledgling field of tissue engineering.

5.   But researchers believe tissue engineering has much broader potential, perhaps one day providing a way to replace entire organs.

6.   But while there is general consensus, even among skeptics, that tissue engineering holds great promise, there is not much agreement on how best to proceed.

7.   Despite all that remains to be done, many feel that tissue engineering will play a large role in the future of medicine.

8.   Dr. Pierre M. Galletti, a leading researcher on artificial organs and tissue engineering who helped found the Brown University School of Medicine, died on Saturday.

9.   Despite the reservations of her colleagues at Harvard, Rupnick said Langer, an investigator at MIT who specializes in tissue engineering, was intrigued by her fat investigations.

10.   If tissue engineering can eventually supply those scarce organs, it could also reduce the need for devices like dialysis machines or artificial hearts, say advocates.
