Before you decide you want to grow and modify your own cells, it is strongly recommended you have at least a little background in basic cell biology. If you have no such background, free courses can be found on the web, with one such course here: https://www.edx.org/course/essential-human-biology-cells-tissues-adelaidex-humbio101x-0. The cell biology page of Wikipedia (https://en.wikipedia.org/wiki/Cell_biology) is also a great resource to explore. Additionally, I recommend you go through the page below on Common Terms, since this will allow you to understand the procedures that are explained here. For any techniques mentioned, there is a Techniques and Procedures page below that will cover much of what you need to know.
