Plastination is the process of embalming or preserving tissue, which was developed and patented by Dr. Gunther Von Hagens. The process was used on human bodies, that were then displayed in the Body Worlds exhibitions across the world.
Michael Jackson's employee was said to have contacted the company a few months ago, causing speculation that Jackson wanted to preserve his body following his death.http://www.tmz.com/2009/06/27/michael-jacksons-body-hold-the-plastic/
