Etymology

Mesenchyme = Meso ('middle') + en-chyma ('in-pouring'). Greek Khyma is related to the words Chemistry, Alchemy ('pouring'), as well as Gum ('tree sap/resin'), all from the ancient Egyptian root word underlying Alchemy, seemingly the ancient name of Egypt, Khemet ('black land' [land the Nile flows over ??]).

Corrections

I would like to correct your page concerning the term "mesenchyme". Mesenchyme is a morphological description of a pleomorphic, migratory cell in loose connective tissue. It is found in both embryonic and adult tissues. It IS NOT DERIVED FROM MESODERM!!!! Mesencyme can be derived from all three germ layers. For example, neural crest, derived from ectoderm (neurectoderm) can form mesenchymal cells that migrate long distances in the embryo. Similarly, endodermal derivatives such as the lung, liver, pancreas can from as outgrowths of the gut but the cells forming these tissues undergo anepithelial-to-mesenchymal transformation and then a mesenchymal-to-epthelial conversion during tissue morphogenesis. Similarly, neoplastic cells in the adult derived from ectodermal or endodermal derivatives discard their epithelial phenotype and assume a mesenchymal appearance while migrating in the connective tissue. In short, mesenchyme is formed from all three germ layers. THE TERM MESENCHYME HAS NO RELATION TO GERM LAYER ORIGIN. My students have quoted Wikipedia in this regard and I have had to correct them about this mistake in your encyclopedia.

I agree, and this article is in serious need of a rewrite. - Quirk (talk) 14:55, 6 March 2008 (UTC)[reply]

Reference Issue

Please note the 2nd reference in the article page. This fake reference should be removed or changed at some point. 71.237.95.8 (talk) 07:04, 1 February 2008 (UTC)[reply]

Further Corrections

I have some further suggestions. As mentioned by the users above, this article could use some editing. Mesenchyme is not derived from mesoderm. It is made of extracellular matrix, ECM, and it's the fluid like properties of the ECM that allow mesenchyme its mobility. http://embryo.asu.edu/pages/mesenchyme ^[1] ^[2] Also, it would be worthwhile to discuss the significance of mesenchyme -- especially during development. Analyzing and discussing epithelial-mesenchymal transformation, for example, would be a good point to start. Epithelial-mesenchymal transformation is a process by which primary germ layer cell populations lose their adhesive abilities and form epithelial. http://embryo.asu.edu/pages/mesenchyme ^[3] Mesenchyme potency (i.e. totipotency, pluripotency, etc.) properties is essential.

Developmental Biology 8th edition, 2003 by Scott is also a valuable resource if you need more information. ^[4]

On another note, 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.
