摘要: Rathke’s pituitary cleft represents the original recess of so-called pouch derived in embryo from ectodermal evagination stomodeum (1,2). In several mammals, for example rat, dog and cat, this persists during postnatal life as a wide fissure separating pars distalis intermedia. It is lined by continuous layer cells termed ‘marginal cells’, contains fluid-like material (colloid) uncertain function, origin chemical composition (3).
