abstract = {The origin of the thymic epithelium, i.e. the cortical
(cTEC) and medullary (mTEC) epithelial cells, from bipotent
stem cells through TEC progenitors and lineage-specific
progeny still remains poorly understood. We sought to obtain
an unbiased view of the incipient emergence of TEC subsets
by following embryonic TEC development based on
co-expression of EpCAM, CD80 and MHC class II (MHCII) on
non-hematopoietic (CD45(-) ) thymic stromal cells in
wild-type BL6 mice. Using a combination of ex vivo analysis,
Re-aggregate Thymic Organ Culture (RTOC) reconstitution
assays and mathematical modeling, we traced emergent lineage
commitment in murine embryonic TECs. Both experimental and
mathematical datasets supported the following developmental
sequence: MHCII(-) CD80(-) → MHCII(lo) CD80(-) →
MHCII(hi) CD80(-) → MHCII(hi) CD80(hi) TECs, whereby
MHCII(hi) CD80(-) and MHCII(hi) CD80(hi) TECs bear features
of cTECs and mTECs respectively. These emergent MHCII(hi)
CD80(-) cTECs directly generate mature MHCII(hi) CD80(hi)
mTECs in vivo and in vitro, thus supporting the asynchronous
model of TEC lineage commitment.},
