Perhaps you should try some spelling variations:
"tissue bioengineering" » "tissue engineering"
"tissues engineering" » "tissue engineering", "tissue engeneering", "tissue engineered"
"issue engineering" » "tissue engineering", "tissue engeneering", "tissue reengineering"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("tissues engineering") OR ("tissue bioengineering"))) OR ("issue engineering")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"tissues engineering\") OR (\"tissue bioengineering\"))) or (\"issue engineering\"))".
• Removing quotes may allow a broader search: (((( tissues engineering ) OR ( tissue bioengineering ))) or ( issue engineering )).
• Adding a wildcard symbol may retrieve word variants: (((("tissues engineering") OR ("tissue bioengineering"))) or ("issue engineering"))*.
