Institute for Biomedical Sciences

A non-profit public benefit organization supporting research in regenerative medicine to produce tissues and organs for implantation in humans.

Our Mission

We will plan and conduct tissue regeneration research using the latest scientific methods to discover and develop the salient factors that mandate targeted and efficient cells growth. Our results and reports can be established as standards for the regenerative medicine industry. We will support young scientists and students who share our goals through awards, scholarships, fellowships and internships. We will apply for government grants and request funding from industry and the general public to support our goals.

Our History

The Microvascular Research Institute was founded in 1979 by faculty members from the University of California, San Diego and the University of Southern California. It was established to investigate the cause, progression, cure and prevention of diseases by studying the smallest blood vessels – capillaries, which are responsible for delivering oxygen and nutrients to all tissues and organs. Later, in collaboration with orthopedic surgeons at Scripps Health our work expanded into the musculoskeletal area resulting in a name change to the Institute for Biomedical Sciences in 1994. We enhanced the performance of artificial hip and knee joint implants using state-of-the art biomechanics and computational approaches. We believe the next scientific breakthrough is the successful bioengineering of cartilage and related tissues for biologic joint replacement. A key to this success is uncovering the optimum external conditions for cells to form cartilage and supporting target tissues. We are now in the process of performing a series of systematic experiments to quantify the effects of mechanical, chemical and electromagnetic forces on cells. With our experience in capillary blood flow we plan to sustain the growing cells in a bioreactor with a tissue engineered capillary network.

Our Team

Our leadership team consists of a senior bioengineer, a clinician and an academician with multidisciplinary expertise in blood circulation, orthopedics, tissue engineering and biomedical instrumentation. We are dedicated to the promotion of research in tissue regeneration with a current focus on the development of biological materials for the repair of damaged and diseased cartilage.
