This article is confusing, it's very poorly written. It doesn't even define the chorionic villi properly. Can someone do something about it? —The preceding unsigned comment was added by 18.104.22.168 (talk) 13:19, 11 March 2007 (UTC).

Is the image for secondary chorionic villi actually tertiary? Blood vessels appear to have invaded the villi...thus, they should be tertiary. Or perhaps I don't understand this well. Savonnn (talk) 04:03, 9 March 2011 (UTC)

I am considering developing this page further as part of an educational assignment in Fall of 2013. If someone else is also working on this, please send me a message and let me know soon, so we donʼt duplicate initial efforts in page development. Vicktory7 (talk) 20:44, 6 October 2013 (UTC)
This article gives greater insight to the role of differential gene expression in stem cells located in the chorionic villi at different stages of development. Information contained in this article could bolster the "Development" section of this article. Vicktory7 (talk) 21:10, 6 October 2013 (UTC)
