user57: The proposal for Cell Culture was created a couple of days ago.  From their description

Proposed Q&A site for anyone involved in the use or research of plant, animal and microbial cell culture including micropropagation, animal tissue and organ replacement, stem cell culture and development and production of metabolic compounds using bioreactors.

It sounds like the questions would be right on topic here (and in fact, I have taken some liberties to simply invite the proposers to Bio.SE).  Another Area 51 user has gone as far as saying that their proposal is a duplicate of Bio.SE. 
However, despite the above description, some of their proposed questions tell a different story, and seem to straddle the Biology and Gardening and Landscaping sites.
For example, http://area51.stackexchange.com/proposals/39091/cell-culture/39095#39095:

What's the best culture media and environment (light/temp/container) for growing Cattleya orchids?

My only qualm is I don't know how to classify that question and the others like it.  I know there are a few plant experts around, so we certainly have the know-how, but would something like that still be considered on topic here?

user69: Personally I think you're completely right in that 95% of content for that proposal would be ably dealt with here - the remainder could either be attempted by our community or given to Gardening, decisions that could be made on a case by case basis (as they are currently) at least until we set a precedent.
