Reem Saud Alhejailan

Dr. Reem Alhejailan is a leading Scientist and Adjunct Assistant Professor at KFSHRC and Alfaisal University in Riyadh, specializing in regenerative medicine, cardiac tissue engineering, and stem cell research. Her work advances human organoid models, iPSC-based disease modeling, and tissue decellularization techniques to better understand and treat cardiovascular and pulmonary diseases. Dr. Al Hejailan develops innovative approaches for cardiac tissue regeneration, including optimized protocols for decellularizing and recellularizing whole organs to create patient-specific scaffolds that reduce immune rejection and address donor shortages.

Her research further explores biomaterial scaffolds, engineered matrices, and 3D disease modeling of conditions such as cardiac dysfunction and lung fibrosis. She has published in high-impact journals, holds an international patent in xenograft immunomodulation, and leads multiple national grants in gene therapy and organ bioengineering. Dr. Alhejailan is also an active contributor to key scientific networks and committees supporting women in science and advanced biotechnology education.
