Apoptosis or Programmed Cell Death

Apoptosis is an important cellular process that allows cells to die in a programmed and organized fashion. This form of programmed cell death is crucial to the stability and equilibrium of living organisms. Such a process is shared amongst vertebrates and invertebrates alike (Miguel-Aliaga et al., 2009). It is easiest to define “normal” development by […]

How Cells Cheat Death

Cells are constantly fighting between life and death. It is believed that once cells go through certain incidences, their death is irreversible. Incidences such as, shrinkage, the breakdown of DNA or mitochondria, condensation of the nucleus, as well as activation of caspases. A new ability to replenished cells was recently discovered; it is called anastasis. […]
