We studied the ultrastructural distribution of fibronectin in the smooth muscle layer of mouse small intestine with affinity-purified antibodies using the immunogold technique. Fibronectin was present over the pericellular area extending from the cell membrane to the extracellular matrix beyond the basal lamina. Distribution of the glycoprotein over the pericellular area was heterogeneous, i.e., it was localized more abundantly in the narrow space between smooth muscle cells, the gaps having a width of 60-80 nm where the two dense bands in adjacent cells matched each other. Such localization suggests that fibronectin contributes to cell adhesion. Within the basement membrane, gold label was localized both in lamina lucida and lamina densa, more densely in the latter than in the former. Fibronectin was also co-distributed with collagen fibers in the extracellular matrix. Within smooth muscle cells, gold particles were observed on rough endoplasmic reticulum and secretory vesicle-like structures. These results suggest that smooth muscle cells synthesize fibronectin and secrete it as a component of the basal lamina and extracellular matrix.

Pages C658-C665: G. R. Wade and S. M. Sims. “Muscarinic stimulation of tracheal smooth muscle cells activates large-conductance Ca2+-dependent K+ channel.” Page C662, Fig. 6: the second half of the trace in A was inadvertently duplicated from B. The revised Fig. 6 below shows the correct channel traces. We wish to emphasize that the scientific point of the figure, the reversible antagonism of the cholinergic response by atropine, as well as the quantification in D, remains sound. The data were filtered at 400 Hz and sampled off-line from digital videotape at 2 kHz. (See PDF)
