The new faces 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.
All are Glasgow players bar Gilchrist, who plays for Edinburgh.
Maitland, the 24-year-old New Zealand-born wing, qualifies for Scotland through grandparents born in Glasgow.
There are recalls for No 8 Johnnie Beattie, who missed out on selection for the 2011 Rugby World Cup, and Richie Vernon, Alasdair Dickinson, Moray Low, Robert Harley and Duncan Weir who were not involved during the recent autumn internationals.
Six players - Chris Cusiter, John Barclay, Jon Welsh, Nick De Luca, Ross Rennie and Scott Lawson - will be added to the squad when they recover from injuries.
Johnson said: "We've chosen this squad with two parameters uppermost in our minds: current form and looking to the future.
"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."
