||P.2115 left column bottom paragraph: "In the young adult mouse, 10 to 20% of total thymocytes are proliferating (BNID 113434). These thymic blasts are mainly located in the cortex and have a particularly high frequency in the outer subcapsular region. The entire cycle lasts about 9 hr, with a 6- to 7-hr S phase and very short G1 and G2 + M phases (primary source)."
