Surface area ratios. II. A stereological method for estimating changes in average cell volume and frequency.

R P Bolender

    The Anatomical Record
    |October 1, 1979
    PubMed
    Summary

    This study introduces a new stereological method to measure cell volume and frequency changes using surface area ratios. This approach simplifies cell analysis by relying on intersection counts, avoiding complex numerical density methods.
