Personal Statement
Dr. Ercelen received her certification in Assisted Reproduction Technology (ART) & Preimplantation Genetic Diagnosis (PGD) at Reproductive Genetics Institute in Chicago in 2000. She established and directed the Genetics and Genomic Sciences Center at American Hospital, Istanbul, Turkey from 2000
– 2010. In September 2011, she was an Associate Professor at the Bahcesehir University Medical School, Department of Medical Genetics. She established and directed the Liv Hospital Department of Regenerative Medicine, Stem Cell Research and Therapy Center, Istanbul, Turkey, and received the first license from the Turkey Ministry of Health for a GMP certified stem cell treatment clinic July 2014.
During her clinical career, she had introduced hundreds of cases into ESHRE PGD Consortium International Society Database. She has consulted with more than a thousand patients and reported clinical diagnostic lab reports for these patients in genetic oncology, molecular genetics, cytogenetics and preimplantation genetic diagnosis. She has introduced hundreds of DNA SNP analysis and personalized reports to patients indicated for preventive medicine.
In regenerative medical clinics, after receiving the stem cell license, using biological and stem cell procedures, many patients with cartilage aliments, scars, diabetic and other acute/chronic wounds, ischemic limb aliments were successfully treated by Dr. Erçelen. She continues to use stem cell therapy for systemic diseases like Covid 19 and stroke.
Dr. Ercelen has contributed to scientific articles in national and international journals. She has been lecturing in national and international meetings, courses, and workshops during her career for student and medical professionals. Her special areas of interest include clinical genetics, prenatal diagnosis, preimplantation genetic diagnosis (PGD), reproductive genetics, preventive/personalized genetics and regenerative medicine/stem cell therapies.
