Article Grading: The following comments were left by the quality and importance raters: (edit · history · refresh · how to use this template) This article needs updating or better still, replacing with a better version. Firstly, growth factors do not have to be proteins. A great many growth factors in plants are hydrocarbons for example. Secondly, it should be stressed out that a significant part of the scientific community reserves the term 'growth factor' for substances stimulating cell growth, the increase in cell mass, and classes mitogens and survival factors separately. Mentioning cell proliferation as the first function of growth factors is therefore very dubious. 131.111.8.99 (talk) 22:18, 27 April 2008 (UTC)

I'm not very familiar with growth factors, but the description seems to be bit different from those for what I'm familiar with...such as EGF, NGF, PDGF, TGF alpha and beta. I'm especially interested in the role of EGF and TGF beta in development.

I don't know if other people think this is of high importance - I think this page could be made much better. Dr Aaron 03:17, 14 November 2006 (UTC)

I agreee it can be made much, much better. As for high importance, the (somewhat arbitrary) measure that we use is that we assign a topic "high" importance if it is generally examined at the lower-division college level (RNA polymerase) or briefly mentioned at the high school level (endoplasmic reticulum). I think that this straddles the line between high and mid, and the class assignment of "start" is dead on. I think its current assignments are fine. – ClockworkSoul 13:16, 14 November 2006 (UTC)
