  • Title: Ultrastructural features of bovine mammary epithelial cells grown on collagen gels.
    Author: MacKenzie DD, Brooker BE, Forsyth I.
    Journal: Tissue Cell; 1985; 17(1):39-51. PubMed ID: 3890266.
    Abstract:
    Bovine mammary epithelial cells cultured on floating gels of rat tail collagen showed two principal cell types, columnar and squamous, with ultrastructural features resembling secretory and myoepithelial cells respectively. Cultures of freshly prepared cells released alpha-lactalbumin into the culture medium and in some cases contained fat droplets, although these did not appear to be released. No ultrastructural evidence of casein synthesis was observed. A notable feature was the failure to secrete a continuous basement membrane. Intermediate filaments were present in abundance in squamous epithelial cells.
