Apoptotic Cell Death in the Chicken Bursa of Fabricius
The bursa of Fabricius is the site of primary B cell development in birds, and has been reviewed extensively elsewhere1–3. It is productively colonized during embryonic life by a small number (<50,000) of B lineage committed precursors which undergo immunoglobulin gene rearrangements either prior to their migration to the bursa or within the bursal rudiment during a short window of time in embryonic development. By about day 18 of embryonic development (day e18) all Ig gene rearrangements in the chicken have been completed and the adult B cells compartment is derived from this small pool of rearranged B cell precursors4.
