The main differences observed when comparing skin with and without stretch marks were at depths between 75 and 95 μm, corresponding to the dermal-epidermal junction and dermis regions and showing differences between normal skin and stretched skin regarding collagen, collagen hydration, and elastin fibers.
CRF-producing cells in the central nucleus of amygdala (CeA) and oval division of the bed nucleus of stria terminalis (BNSTov) are also involved in stress adaptation and mood control.
A selective THIP-induced activation of CRF-expressing neurons in the oval part of the bed nucleus of stria terminalis may constitute a novel mechanism for inducing plasticity in a population of VTA DA neurons and aversive behavioral states.
Because aldosterone applied alone stimulates both collagen and elastin deposition in cultures of fibroblasts and in cultures of skin explants derived from dermal stretch marks, we postulate that this steroid should be used in the treatment of damaged skin that loses its volume and elasticity.
These observations suggest that expression of collagens, elastin and fibronectin genes are apparently decreased, and that there is a marked alteration of fibroblast metabolism, in striae distensae.
We detected Cx26 and Cx30 expressions in the type I, II& V fibrocytes in the spiral ligament, fibrocytes of the spiral limbus, in the supporting cells of organ of Corti, inner and outer sulcus cells, and in the basal cells of the stria vascularis.
We previously showed that, in male mice, the estrogen receptor-α (<i>Esr1</i>) and aromatase (<i>Cyp19a1</i>) genes are essential to the sexually dimorphic formation of the anteroventral periventricular nucleus (AVPV) and the principal nucleus of the bed nucleus of the stria terminalis (BNSTp), but the estrogen receptor-β (<i>Esr2</i>) gene is not necessary.
Cx26 and Connexin-30 (Cx30) encode gap junction proteins expressed in supporting cells of the organ of Corti, the spiral limbus, stria vascularis, and in fibrocytes of the spiral ligament.
