Carat volunteers sign up as stem cell donors for Hattie’s Heroes


Hundreds of people from across the Dentsu Aegis Network have signed up as stem cell donors for Hattie’s Heroes – thanks to Harriet Smith and Yvonne O’Watson, both PAs at Carat UK. They explain what it’s all about…

blood cancer leukaemia Hattie's Heroes

Hattie’s Heroes was set up by the family of Hattie, a three-year-old girl who has been diagnosed with acute lymphoblastic leukaemia.

Harriet got involved through Facebook – her dad lives in the same town as Hattie and posted something about the cause. She saw it and thought she could do something to help. 

She asked Yvonne O’Watson to come on board as she had previously helped out with a successful campaign for her friend, also affected with a form of blood cancer ‘Shake for Mike'.

One of the aims of the Hattie's Heroes campaign is to sign up 1,000 new stem cell donors on to the worldwide Delete Blood Cancer registration list in 2016.

We thought this was something that Dentsu Aegis Network could help with so we set up a registration event. Our aim was to get 200 people from the building registered – we actually signed up 366 so we’re really pleased!


All it takes to go on to the UK stem cell registry is a two minute cheek swab. If anyone else is interested in registering, you can sign up online at and they will send you the swab, which you can do yourself.

Hattie is currently having chemotherapy at Great Ormond Street HospitalShe’s continuing to fight the disease and there are many more like her.

Every 20 minutes, someone in the UK is told they have a blood cancer like leukaemia, lymphoma or myeloma. That’s over 70 people a day, 30,000 people a year, and sadly, many of these are children.


Blood stem cells from a matching donor could save their lives. There are around 2000 people in the UK searching for a blood stem cell donation each year and over 37,000 people waiting worldwide. Sadly, less than half of the people in the UK diagnosed with a blood cancer find a suitable donor. That’s why it’s so important that we encourage as many people as possible to register as donors.

There is also a fundraising page, raising money for Leukaemia Care, a national blood cancer support charity that provides vital information, and support to all whose lives have been affected by a blood or lymphatic cancer diagnosis, which you can find by clicking here.
