Harvard Review of Growth Factor Delivery Systems

Author: Russell Health, Inc.

“Growth factors are critical signalling molecules that instruct cells during development, and one may achieve tissue regeneration in the adult by enabling control over growth factor delivery.”

-K. Lee et al., Harvard University

Sophisticated material systems capable of using growth factors to programme native cells. Polymer systems can be functionalized to recruit specific subsets of cells, where the cells are programmed to execute a specific task after leaving the material that can be to maintain, regenerate or even to destroy a particular tissue or subset of cells at a local or distant site.

Harvard Review: Growth factor delivery–based tissue engineering developments

The systems and similar Stem Cell Recruitment™ products reviewed that can recruit cells into a scaffold, tend to be versatile and could be used for many different applications. “For example, systems that can recruit cells into a scaffold, programme the cells appropriately and stimulate cells to leave the scaffolds may allow one to bypass the ex vivo culture and manipulation common to current cell therapies.”

Tissue engineered systems like acellular amniotic fluid or amniotic tissue can be functionalized to recruit specific subsets of cells, where the cells are programmed to execute a specific task after leaving the material that can be to maintain, regenerate or even to destroy a particular tissue or subset of cells at the site of inflammation and injury within the soft tissue or joint.

This review provides an overview of growth factor delivery in tissue engineering. Certain fundamental issues and design strategies relevant to the material carriers that are being actively pursued to address specific technical objectives are discussed. Recent progress highlights the importance of materials science and engineering in growth factor delivery approaches to regenerative medicine.

Human Tissue Therapy

Acellular minimally manipulated tissue allografts are utilized to help treat a wide variety of conditions and are shown to help the body boost its ability to heal itself. The allografts help promote the body’s own healing process to assist in the reconstruction and regeneration of injured tissue. This can lead to an alleviation of pain, and a quick recovery.
