Professor Mutlu Arat is one of Turkey’s most experienced hematologists in adult bone marrow transplantation. After graduating from Hacettepe in 1991, he received specialized training in HSCT at the University of Vienna (Austria, 1996–1997) and later worked as a visiting professor at the University of Minnesota (USA, 2008).
In 2010, he founded his own Adult Stem Cell Transplantation Center at Florence Nightingale Hospital and led it as Director until 2024. By 2019, more than 1,100 transplantations had been performed at the center; the total number of procedures performed under his leadership over his entire career (Ankara + Istanbul) is estimated at around 1,400.
Since 2024, Professor Arat has been seeing patients at Memorial Şişli Hospital in the Department of Internal Medicine and Hematology. He has served as a JACIE inspector for the international accreditation of transplant centers since 2004 and is a member of the Scientific Advisory Board of the Turkish Ministry of Health. His scientific profile includes more than 350 publications and over 6,000 citations on haploidentical transplantation, myelodysplastic syndrome, and lymphomas.

Areas of specialization:


Memorial Şişli is the flagship hospital of the Memorial Healthcare Group, established in 1995 and admitting its first patients in February 2000.
It is the first hospital in Turkey (and the 21st in the world) to receive Joint Commission International (JCI) accreditation, confirming international standards of quality and safety.
The hospital occupies more than 53,000 m² and has 252 beds, 13 operating rooms, 4 intensive care units, and 3 laboratories. The clinic includes organ transplantation centers, IVF, genetics, stroke treatment, breast disease, an oncology center, a da Vinci robotic surgery center, and a Bone Marrow Transplantation Center.
For Professor Arat’s patients, it is important to note: Memorial Şişli has its own Bone Marrow Transplantation Center, a multidisciplinary oncology center for the treatment of lymphomas, leukemias, and myeloma, a genetics and molecular diagnostics laboratory (necessary for typing and MRD monitoring), as well as an international patient services department serving patients from 167 countries — including translators and logistical support.
