The uncapped 10 are full-back Peter Murchie, wings Sean Maitland and Tommy Seymour, centres Alex Dunbar and Peter Horne, scrum-half Sean Kennedy, hooker Pat MacArthur, lock Grant Gilchrist and back-row forwards Ryan Wilson and Chris Fusaro.
Johnson has also recalled Johnnie Beattie, Richie Vernon, Alasdair Dickinson, Moray Low, Rob Harley and Duncan Weir.
Chris Cusiter, John Barclay, Jon Welsh, Nick De Luca, Ross Rennie and Scott Lawson are currently sidelined but will be
added to the squad when they recover from injuries.
"We've chosen this squad with two parameters uppermost in our minds: current form and looking to the future," said Johnson.
"Where two players have been vying for the one spot in areas such as the back-row, we've gone with the form option.
"I've been impressed with a number of the young fellows who've helped Glasgow to second place in the Rabo, especially by their work ethic and determination to improve.
"This squad is for our training camp in Glasgow next week and we still have the option to add to it for the Six Nations."
