ACTA1 and Hernia: The α-SMA+ cells were absent from hAF of AIS samples (Fig. 5A (a–d) and 5B), as well as in a high percentage of herniated samples (in 33.3% of the protused hernias, 47% of the contained hernias and 38.5% of the uncontained hernias), suggesting a high heterogeneity of the α-SMA expression in hAF.
