Morphological features of early human thymus development

(A-C′) Images show microdissected human fetal thymic primordia at the ages shown, except for B, which shows anatomical details of the exposed chest cavity to indicate relative locations of thymic primordia, carotid artery and heart.

B″ shows detail from lower part of thymic primordium (i.e. the leading edge during migration). Arrowheads indicate thymic primordial; white arrow in C indicates mesenchymal capsule. Images are representative of at least two independent analyses.

H, heart; Th, thymus; Wk, week.

Embryos - mid- to late week 6 (17), week 7 (18-19), early to mid-week 8 (20-21), and weeks 9, 10, 15-16 and 17, with days/weeks indicating days/weeks post-fertilization.
