Any plans to incorporate thymocytes -- T cells, but mostly not yet of the functional variety -- into the profiling? Will special provisions be needed to really understand the VDJ information in this context, given the changes in the pre- to post-selection repertoires?

For thymocytes, is definitely on to run balanced sampling, otherwise data will be overwhelmed by pretty boring DPs. What is currently on the books is to rebalance by over-sampling double-negatives and intermediate/mature TCRhi cells. But there are probably sharper ways to rebalance (especially for the gdT side of things)
And yes, having some relation to TCR strength-of-signal would definitely be desirable. Not sure that a single-chain TCR transgenic would give us that handle (variability in the second chain would likely create a wide range of affinities for thymic MHC-peptide complexes). But selection by tetramer staining (that one perhaps coupled with a single-chain Tg), or focusing on super-antigen reactive T cells, might get us there.
