Trump will meet Liu He at the White House, signalling to end the tariff battle between the two countries.
Trump will meet Liu, who is also China's top trade negotiator, in the afternoon at the White House, according to an official scheduling note from the president's office.
US and Chinese negotiators are working to find a binding agreement to address Trump's complaints about years of unfair treatment of US companies by China, which would allow a rollback of the tariffs hitting businesses in both countries.
US officials say that China has been using unfair trade practices for years by heavily subsidizing its companies while snatching the technological know-how of American firms.
On March 29, Trump said that negotiations to end the bruising tariffs battle with Beijing were going "very well," but reiterated that he will only accept a "great deal."
Trump said that US and Chinese negotiators were close to a deal, but US officials, however, played down expectations of an imminent agreement.
The research "provides evidence that healthy cells in mammals can also efficiently repopulate adult tissues, replacing unfit or damaged cells," wrote professors Ganna Bilousova and James DeGregori.
And they said the research offered "proof-of-principle" that the two chemical compounds could combat ageing.
"Future studies are needed to determine the mechanisms of cell competition in other tissues, and to identify compounds capable of reversing ageing in other organs," they said.
Nishimura told AFP that the work could eventually lead to products like creams or tablets that could stop skin deterioration and promote repair.
"We are going to collaborate with the pharmaceutical or cosmetic companies for the clinical use of the chemicals," she said.
She said additional research would investigate whether the same process might also be at work in other parts of the body that have so-called epithelial cells as skin does.
