Introducing myself

Hello everybody. I'm new to the forum so this is my introduction.

I'm 65 and retired from teaching in 2008. I suppose like everybody here I've got arthritis so I won't bore you with any details, I'm sure you understand only too well what that's like.

I had horses most of my adult life but the last of them died in 2007 and my pets now are a pair of house rabbits who certainly keep me busy.

I'm not sure if this is the right part of the forum to ask but here goes anyway. Does anybody know whether any research is being done into using stem cells to improve the condition of joints? If this is being discussed somewhere else I'll be grateful for a link to the discussion.
