Varicella (chickenpox) , rubella, hepatitis A, shingles and one preparation of rabies vaccine are all made by growing the viruses in fetal embryo fibroblast cells. Fibroblast cells are the cells needed to hold skin and other connective tissue together.
Character (arts) A character (sometimes known as a fictional character) is a person or other being in a narrative work of art (such as a novel, play, television series, video game, and film). The character may be entirely fictional or based on a real-life person, in which case the distinction of a fictional versus real character may be made.
A character entity is a method used to display special characters normally reserved for use in HTML. For example, the less than (<) and greater than (>) are used as part the HTML tag structure, so both symbols are reserved for that use.
