[The reactivity and mechanical sensitivity of the secretory and myoepithelial cells in the alveoli of the murine mammary gland].

The data obtained suggests that the period following the cessation of suckling their young in mice induces no inhibition of the contractile response of myoepithelial cells or of the milk ejection. For the first time, the inhibitor (Gd3+ ions) of the mechanosensitive ion channels was shown to inhibit the secretory and myoepithelial cells responses in the mammary gland alveoli.
