Re: [Cellfatewp9] hES in WP9

If the team is happy to iPS cells Brian, Horizon is happy. If you ultimately need the iPS cells to differentiate into particular cell-types as part of the programme, I can recommend a new spinout from Addenbrooke’s (DefiniGen) that has built up a large bank of iPS cells with preferred differentiation patterns (along with good differentiation protocols) that may be interested in joining to replace Cellartis. I can get in touch if this sounds of any interest.

The permits we have from both the UK and European powers that be regarding human ES cell use specify that we are only allowed to use lines that would have been provided by Cellartis. In order to use any other hES line, we'll have to modify this paperwork and await permission. Therefore I suggest we get started using a human iPS line. To be honest I'm not sure how much benefit there is in using hES vs hiPS for these studies, given the general lack of clarity about exactly what a human "Pluripotent" cell is anyway. Austin Smith has confirmed that he is willing to provide both an iPS and/or a hES line for our work. So, assuming no one has any objections, I'll get the iPS line and Horizon can get started targeting this line now. I can also apply to use Austin's hES line, but whether we actually use it or not depends upon whether anyone has strong reasons for doing things in hES cells rather that iPS cells. I'd be happy to hear your thoughts on this. Best wishes, Brian Brian D.
