Stem Cell Biology
Our members are conducting foundational research to enhance our understanding of stem cell biology to help unlock the full potential of regenerative medicine and transform the way we study and treat disease.
Overview
Stem cells Cells that have the ability to differentiate into multiple types of cells and make an unlimited number of copies of themselves. Stem cells Cells that have the ability to differentiate into multiple types of cells and make an unlimited number of copies of themselves. have the remarkable potential to self-renew and differentiate into the various specialized cell types found in the body. In addition to generating all the cells and structures of the human body, they serve as a sort of internal repair system, dividing to restore or replace cells lost throughout a person’s life. Our researchers are leveraging their expertise across a wide range of disciplines and technologies to build a deep foundational understanding of stem cell function, gaining critical insights into how stem cells can be harnessed toward new therapies that regenerate damaged organs, repair injuries and prevent age-related diseases.
Uncovering these underlying principles provides a solid framework for more applied research, yielding insights into humanity’s most complex medical mysteries and opening up avenues to enhance the body’s inherent ability to heal. Center members are developing improved methods to generate induced pluripotent stem cells iPS cells are cells taken from a patient that are reprogrammed so that they can undergo differentiation into any type of cell in the body. By maintaining the genetic code of the patient, iPS cells play a crucial role in disease modeling and regenerative medicine. induced pluripotent stem cells iPS cells are cells taken from a patient that are reprogrammed so that they can undergo differentiation into any type of cell in the body.
