Stem Cell Apoptosis and Signal Transduction

Apoptosis is the cell death which leads to a programming sequence of the elimination of old, unnecessary, unhealthy cells. This process is also known as cell suicide. When a cell commits suicide then the caspases become active. The signal transduction is a process in which the signals are transferred in an organism across the cells. In this process the proteins are termed as the receptors. The protein receptor gets signal through a primary messenger and then, undergoes conformational changes which changes its shape and interacts with molecules surrounding it.
