	abstract = {Mammary tissues from virgin, prepartum and lactating ewes were  examined by in situ hybridisation with a 35S labelled cRNA probe  derived from the bovine alpha-lactalbumin gene. Expression of alpha-  lactalbumin was absent in the virgin udders. In the pregnant gland,  alpha-lactabumin expression was found in some secretory alveoli but not  in others, even though they appeared histologically similar, containing  milk or colostrum and fat globules. Fully lactating ewes have several  levels of alpha-lactalbumin expression. In secretory epithelium, it was  high in collapsed thick walled lactating alveoli, slightly less in  distended thin walled lactating alveoli with homogeneous contents and  absent from alveoli containing an abundance of large fat globules.  Beta-cytophasmic actin expression was the reverse of this. These  observations are intriguing and suggest a number of hypotheses.  Firstly; that alpha-lactalbumin gene expression is linked to the long  term secretory activity of cells and drops off once cells are resting or  regressing. Secondly; that alpha-lactalbumin gene expression is highest  in those alveoli which are "filling up" and lowest in those which are  full or have just been milked out. That is, there are cyclical  variation in expression. And thirdly; that there is distinct  compartmentalisation in the lactating gland, and synthesis of alpha-  lactalbumin mRNA (and the protein?) occurs in cells which synthesise  little fat.  },
