    • Disclosed are compositions and methods for maintaining the integrity of smooth muscle, particularly vascular smooth muscle. Vascular diseases are characterized by an excessive build-up of vascular smooth muscle cells, resulting in an occlusion of a blood vessel, and/or by loss of elasticity in the blood vessels. Causes of blood vessel occlusion include smooth muscle cell proliferation and inflammatory responses. Inhibition of the proliferation of smooth muscle cells or inflammatory responses represents an effective treatment for vascular disorders, such as atherosclerosis and restenosis. Treatment may include administration of a morphogenic protein. The protein itself may be delivered to the site of vascular occlusion or the protein may be delivered by a vector, such as an adenoviral vector containing a DNA insert encoding a morphogenic protein. Such compositions and methods may also inhibit the responses of smooth muscle cells to various traumas, such as exposure to toxic agents. All of these treatmetns operate to preserve the cell phenotype by inhibiting an increase in extracellular matrix proteins, such as collagen, or by maintaining the normal balance of extracellular matrix proteins, such as Types I and III collagen.
    • 公开了用于维持平滑肌,特别是血管平滑肌的完整性的组合物和方法。 血管疾病的特征在于血管平滑肌细胞积聚过多,导致血管闭塞和/或血管丧失弹性。 血管阻塞的原因包括平滑肌细胞增殖和炎症反应。 抑制平滑肌细胞或炎症反应的增殖代表血管疾病如动脉粥样硬化和再狭窄的有效治疗方法。 治疗可包括施用形态发生蛋白。 蛋白质本身可以被递送到血管闭塞部位,或者蛋白质可以通过载体递送,例如含有编码形态发生蛋白的DNA插入物的腺病毒载体。 这样的组合物和方法也可以抑制平滑肌细胞对各种创伤的反应,例如暴露于有毒物质。 所有这些治疗方法通过抑制细胞外基质蛋白如胶原蛋白的增加或通过维持细胞外基质蛋白如I型和III型胶原的正常平衡来操作来保持细胞表型。
