July 2004: "Programmed cell death" had been, until today, redirected to "Apoptosis". But for some time now, it became more and more necessary to have a separate article on PCD. First, because, PCD and apoptosis are not synonimous (as explained in the new article on PCD). One of the founding figures in the field, Richard Lockshin, has pointed this out repeatedly (see, for instance, Lockshin and Zakeri: "Programmed cell death and apoptosis: origins of the theory", Nature Reviews Molecular Cell Biology, cited in the article), as well as other authors and researchers (see both Schwarz et al.and Bursh et al., as referenced in the article).

Another reason for splitting the apoptosis article is that it was getting too big, at the same time that it was encompassing concepts that did not properly belong there, such as plant PCD. -- jaimeglz

April 2006: I totally agree. I am researching on PCD besides caspase-dependent apoptosis and i am grateful for the separation of apoptosis from PCD. PCD is more than apoptosis and there are diverse regulated pathways for a cell to die ;-). -- lt

December 2007: It needs to talk about recent studies on PCD in bacteria - GASP phenotype, toxin/antidote addiction modules, and possibly the entericidin locus. -- jinkbl0t —Preceding unsigned comment added by (talk) 20:22, 3 December 2007 (UTC)


If we're going to mention cornification as a type of programmed cell death, why not also discuss keratinization of epithelia in the formation of skin and nail? (talk) 15:20, 5 February 2009 (UTC)

“[PCD] usually confers advantage during an organism's life-cycle”[edit]

What advantage exactly does PCD confer to the organism? I didn't find an explanation in the article. One should probably be added; if not in the lead section, then in the body of the article. EIN (talk) 07:57, 8 January 2013 (UTC)

I've copy-pasted the following text from the apoptosis article to the lead section of this article, but I'm hoping to hear about a post-natal advantage.

For example, the differentiation of fingers and toes in a developing human embryo occurs because cells between the fingers apoptose; the result is that the digits are separate.

Well there are many many necessary physiological examples of post natal physiological apoptosis.. eg in the thymus.. Apoptosis is part of the reason why we do not grow clones of autoreactive T lymphocytes (but it is combined with other mechanisms like anergy etc to prevent autoreactive ones amonth the surviving autoreactive lymphocytes). --Dr.saptarshi (talk) 17:14, 21 January 2013 (UTC)
