A parliamentary select committee report this week concluded that Wiggins, and possible support riders, had taken performance-enhancing drugs to prepare for the Tour de France under the guise of legitimately treating a medical condition.
"I call for the doctor and Brad to come forward and answer these questions, they are not for me".
Former Team Sky coach Shane Sutton, who gave evidence to the committee past year, was asked about a treatment administered to Wiggins on the team bus after winning the 2011 Criterium du Dauphine.
Froome is still free to race while his case is ongoing, but Lappartient believes it would be awful for the sport if the Briton was to compete in this year's Tour de France with his case unresolved.
Sutton also denied suggestions from a "well-placed source" quoted in the report who told the DCMS Select Committee that tramcinolone was used by Team Sky for its performance-enhancing benefits.
Speaking to BBC Radio 5 live, she said: "For the past three years UK Anti-Doping have made submissions to the World Anti-Doping Agency to see glucocorticosteroids included on the banned list of substances in sport at all times".
However, Sutton said: "I understand he was treated on the bus, I thought it was public knowledge".
In an interview with the BBC yesterday, Lappartient expressed his disappointment at the findings of the Department of Culture, Media and Sport's "Doping in Sport" report, suggesting this new information could lead to a fresh inquiry.
Wiggins has declined a request to comment from Press Association Sport but Team Sky has reacted angrily to the suggestion it was gaming the TUE system.

"If I was in a different team, maybe it wouldn't - but the way the world is at the moment, it's going to come out and people are going to judge me on that".
But Froome said: "There's a process for me to follow and a process for me to demonstrate that I've not done anything wrong, and that's exactly what I plan to do".
The American delivered a scathing assessment of the former Olympic champion and Dave Brailsford, the Team Sky principal, who remained silent amid further calls for his resignation. "I really would like to know".
"It's sad to see that when Team Sky was launched, I remember they say 'we will be clean, we will win races and be clean, more white than white". I have no recollection of training with that group, when they were all together.
"I can only speak from my own experiences in the team". I certainly have a very different picture to what's been painted in the headlines.
Sir Bradley claimed that the one anonymous source in the report was attempting to smear him, before asserting the process had been a "complete mess of innuendo and rumour".
"I have never seen anything like that". I'm proud to be part of the team.
Although Froome turned up with a level of the asthma drug salbutamol double the legal limit en route to winning the Vuelta a Espana almost six months ago, his case is yet to be resolved.
Lappartient added to have such a prominent rider under suspicion at the Tour de France in July "would be a disaster for the image of cycling, even if on a legal point of view he has a right to ride". "I would not have stayed so long, I would not have been in the team, I would not still be in the team, if I did not believe in the team and the people around me".
