||p.547 2nd paragraph:"If [investigators] assume that human thymic output is maximal at birth and comparable to the level of thymic export in mice (~2% of total thymocytes exported per day) (ref 103 BNID 102647), and that total thymocytes at birth are = 50 × 10^9 (primary source), then thymic output per day in normal newborn subjects will be = 10^9 new naive T cells."
