Talking to cancer cells to kill themselves

Through the study of cell development it is clear that through the process of apoptosis cells that are not fit enough or are considered to be the threat to the organism are directed to commit suicide and thus minimising the threat to the organism.

Apoptosis was initially described by its morphological characteristics, including cell shrinkage, membrane blebbing, chromatin condensation and nuclear fragmentation. The realization that apoptosis is a gene-directed program has had profound implications for our understanding of developmental biology and tissue homeostasis, for it implies that cell numbers can be regulated by factors that influence cell survival as well as those that control proliferation and differentiation. Moreover, the genetic basis for apoptosis implies that cell death, like any other metabolic or developmental program, can be disrupted by mutation
