Research Overview

Stem Cell Therapeutics are Expected to Advance Tissue Engineering and Organ Transplantation

Regenerative therapies such as stem cell manipulation are developing treatment procedures for damaged tissues and organ failures. The unique ability of stem cells to divide indefinitely and differentiate into specific cell types allows them to form various tissues of the growing embryo during in vivo regeneration. Researchers are depending upon this discovery to assist in the replacement of damaged tissues and fabrication of viable organs for implantation. One approach to engineering new tissues or organs is to induce stem cells to differentiate into organ-specific cells and then seed them onto a scaffold to create a three-dimensional structure. Computer-aided design and manufacturing technology also creates sophisticated tissue constructs using stem cells, connective tissue, and growth factors. Stem cell therapies are emerging as popular options for bone and cartilage repair and alternatives to existing treatment options such as transplantation, surgical repair, artificial prostheses, and drug therapy. Stem cell therapies, in addition to cost savings, eliminate the difficulties associated with shortage of donor organs.

This research produced by the Technical Insights business unit of Frost & Sullivan analyzes the new and emerging technologies that enable stem cell therapeutics to move from the laboratory into the commercial world. It analyzes innovative tools and technologies developed by researchers at successful companies, including small startups. It also analyzes major technology drivers and challenges. The research service is designed to help participants identify potential collaborators, stay ahead of the competition, and stay shoulder-to-shoulder with critical developments.

Growing Debate over Embryonic and Adult Stem Cells

Biological hurdles and potential opportunities prevail in the development of adult stem cell (ASCs) and embryonic stem cell (ESCs) technologies for tissue engineering. "While ASCs cannot be obtained in sufficient numbers to actually regenerate tissues, ESCs, in addition to the ethical and political controversies, are faced with uncontrolled differentiation and immunological obstacles that compel patients to take long-term immunosuppressive drugs," explains the analyst.

Often referred to as 'therapeutic cloning', ESCs face political, practical, and ethical hurdles associated with the source of cells, which is primarily surplus stocks stored in fertilization clinics or germ cells derived from aborted fetuses. Conversely, ASCs come from peripheral blood or even fat and avoid opposition on moral or religious grounds. However, individual success stories have proven that ASCs and ESCs can coexist. For example, while ESCs repair damaged spinal cords in rats, ASCs improve heart function in patients with heart failure.

Numerous Opportunities for Stem Cell Therapeutics in Nervous System Disorders

A major focus of research today is to use stem cells to regenerate tissues for replacing destroyed or dysfunctional cells in the brain or spinal cord in neurological diseases. Nervous system diseases such as Parkinson's disease (PD), Alzheimer's disease, and multiple sclerosis are ideal targets for stem cell therapy. "PD caused by degeneration of dopamine (DA)-producing neurons may be an exceptional target for stem cell therapies," says the analyst. "Inducing ESCs to differentiate into cells with similar functions as DA neurons may re-innervate the brain, release dopamine and improve the motor function."
