[The cell membrane: a frontier between 2 worlds]

R C de Sousa

    Schweizerische Medizinische Wochenschrift
    |November 12, 1977
    PubMed
    Summary
    This summary is machine-generated.

    The plasma membrane acts as a selective barrier and regulates cell interactions. Its dynamic structure, including transport pathways and receptors, is crucial for cell communication and understanding diseases.
