The atrial myocardial cells of mouse heart: a structural and stereological study
MS Forbes, EE Van Niel, SI Purdy-Ramos - Journal of structural biology, 1990 - Elsevier
Structural and stereological studies of mouse atrial myocardial cells, carried out in the same
fashion as our previous investigations on mouse ventricle, demonstrate an extremely well-
developed sarcoplasmic reticulum (SR) in atrial cells. The volume fraction (V v) of the SR
exceeds 12% in mouse atrial cells; perimyofibrillar network SR constitutes the major portion.
We have confirmed the findings of Bossen et al.(1981, Tissue Cell 13, 71–77) of a difference
between atria in terms of coupling density, the right atrium having a significantly lower …
