This regenerative braking process is one of the more sophisticated fuel-efficiency tricks.

Each year, the focus of attention seemed to shift as research scientists continued to gather new information about the skin's natural regenerative processes.

Switching on the regenerative process with drugs, should that prove possible, would be cheap by comparison, he said.

Else, the process is called a delayed regenerative process.

The regenerative process in him had been destroyed by disease.

Now we are involved in a regenerative process.

The length and efficiency of recovery is depended on the regenerative process that may require 6 to 18 months.

"I believe it's the regenerative process of the arm of the starfish, sir."

"Well, yes, sir, working on the regenerative process of the arm of the starfish."

Many important discoveries were made during this period, which led in part to the general conclusion that progenitor cells are required for most regenerative processes.
