The campaign also drew the support of London Mayor Sadiq Khan, who recently dubbed Sharon’s daughterin- law, Rabbi Miriam Berger, as “the coolest rabbi in the world.” Khan retweeted a plea for help by Rabbi Berger’s Finchley Reform Synagogue “to help save a life today.”Comedian Matt Lucas, boyband Blue, adventurer Bear Grylls and presenter Jeremy Kyle are among the host of British stars who have shared the #Spit4Mum campaign online.“We’ve been incredibly moved by the global support from celebrities on social media,” Sharon’s daughter Caroline said. “Now I hope we can turn those tweets into sign-ups to help save my mum’s life from blood cancer. We are incredibly grateful that people in the public eye are putting the weight of their social media presence behind our #Spit4Mum campaign and using their celebrity status for the greater good.”Her brother, Jonni, added: “We’ve had some amazing social media support which has taken our appeal to new audiences. It’s fantastic to see people getting behind our campaign so quickly. Retweets raise awareness but people have to take action, and that is the hard part.”Jonni and Caroline are going through this ordeal for a second time. Sharon was diagnosed with acute myeloid leukemia (AML) in 2012, and was told that the only available cure was a stem cell transplant from an unrelated donor. That was the first time her dedicated children and husband launched their campaign to encourage more people to join the bone marrow registry.Sharon found a match within weeks, and had an apparently successful transplant in May 2013. But three years later, a routine blood test revealed that the aggressive nature of her illness meant the cancer has returned, requiring a second transplant.A friend of mine has leukemia & needs a lifesaving stem cell donor – it could be you – please register & RT @AnthonyNolan @DKMS_uk #Spit4Mum
