Countless divisions of a single-celled zygote produce an organism of astonishing cellular complexity and organiza- tion. Any individual cell is bound to die, because cells are subject to wear and tear as well as to accidents. 25 million cells are undergoing division each second in an adult human and blood cells renewed at the rate of about 100 million per minute. If an organism is to continue to live

1. (4 pts) An early study in the development of peptide-presenting biomaterials showed that polymer surfaces bearing RGD peptides at a density equivalent to -10 peptides per each cell was sufficient to promote cell attachment, spreading and subsequent cell growth. In contrast, when whole fibronectin protein was adsorbed to polymer surfaces, it was found that many more copies of the

1 . The chara cte ristics of the n euronal cell Wha t would come to your mind as a definition? It is a cell of the brain: that is not correct, it is more widely spread: CNS = brain + spinal cord, SN P, ente ric s ystem. It is an exc itable cell: it is tr ue but this property is s hared with other cells. Muscles: striated musc le, heart. And other cells too such as endocrine cells present an exc itabilit y that is the property to gene rate action
