Wilshere, 19, has been with the Gunners since he was nine years old and began to establish himself in the first team at the start of last season after a successful loan spell at Bolton Wanderers in the second half of the 2009/10 season.
Although he is currently sidelined until at least January or February following major ankle surgery, Wilshere has pledged his career to the club.
"Can I promise I will be at Arsenal forever? I can promise that, yes," he told reporters.
"I've been at the club since I was nine and I've learned to love it. From the Patrick Vieira days, to Dennis Bergkamp, Cesc Fabregas, I've watched them come through and move on.
"But now there's a crop of new players, Aaron Ramsey, myself, Kieran Gibbs, hopefully we can really create something special. I love the club and I want to be part of its future."
Arsenal have recovered after a poor start to the season and have climbed to seventh in the Premier League table after winning their last four league matches since a 2-1 defeat at arch-rivals Tottenham Hotspur on October 2.
