Injectable Tissue Engineering

INJECTABLE TISSUE ENGINEERING

My part of the assignment is to provide a detailed history of Injectable Tissue Engineering. I must also provide details how Injectable Tissue Engineering affects the environment.
Ttissue engineering has advanced dramatically in the last 10 years, offering the potential for regenerating almost every tissue and organ of the human body. Tissue engineering and regenerative medicine remain a flourishing area of research with many new potential treatments for many disease and amputations. The advances involve researchers in a multitude of disciplines, including cell biology, biomaterials science, and Injectable Tissue Engineering of cell material interactions. Tissue

These researchers added cartilage cells to a light-sensitive liquid polymer and injected it under the skin on the backs of mice. They then shone ultraviolet light through the skin, causing the polymer to harden and encapsulate the cells. Over time, the cells multiplied and developed into cartilage. More recent approaches to Tissue Engineering is using Injectable gels for implantation. This procedure is less invasive than prior attempts at Tissue Engineering. There are thousands of cases each year with traumatic injury to cartilage and bone fractures occur annually. Adult cartilage does not normally regenerate after injury leading to complications from sports and other physical injuries.

Injectable Tissue Engineering and the Environment
The environmental risks of Injectable Tissue Engineering are generally considered to be low because most of the materials involved are biodegradable. In addition, human cells do not survive long outside controlled laboratory conditions and production conditions are strictly controlled.
Additionally, in the late 1970's, NASA began focusing on tissue engineering and how these materials behave in space. Their efforts focused on development of techniques for three-dimensional cell and tissue culture. They began engineering laboratory cultures which were similar to human tissue to be used as models to conduct space research and research on
