Información del artículo
El número de células de un organismo está regulado por un balance entre la proliferación, la diferenciación y la muerte celular. Sin embargo, el equilibrio entre la proliferación y la muerte de una población celular puede estar alterado por un aumento o una disminución de uno de estos procesos. En particular, cuando la muerte celular ocurre en menor medida de lo normal, se observan alteraciones que conllevan acumulación de células. De igual forma, un aumento de la muerte celular podría ser responsable de la pérdida de células y sus enfermedades asociadas. A este respecto, la muerte celular se ha considerado como un mecanismo relevante que contribuye a la regulación de la vida.

The number of cells in an organism is determined by a balance between cell proliferation, differentiation and death. However, the normal equilibrium between proliferation and death of a specific cell population is sometimes altered by an increase or decrease in either of these processes. For example, when cell death occurs to a lesser extent than required the result is an abnormal accumulation of cells. Likewise, an increase in cell death results in the loss of cells and possibly an associated disease. In this respect, cell death is considered to be an important mechanism for the regulation of life.
