Advances in the study of mesenchymal stem cells in obstructive sleep apnea hypoventilation syndrome / 中国临床药理学与治疗学

ABSTRACT

Mesenchymal stem cells (MSCs) are self-regenerating, rapidly proliferating pluripotent stem cells that depend primarily on their derived pro-angiogenic, inflammatory regulatory, and trophic factors to exert beneficial effects that attenuate deleterious inflammatory responses, reduce vascular damage, and promote tissue repair and regeneration. Obstructive sleep apnea hypoventilation syndrome (OSAHS) is a chronic disorder marked by oropharyngeal collapse during sleep, resulting in transient reduced airflow, large fluctuations in intrathoracic pressure, and intermittent hypoxia and hypercapnia. OSAHS subsequently cytokine-mediated inflammatory cascades, oxidative stress, and ischemia, recruit MSCs from inflamed and damaged tissues through MSCs-derived of anti-inflammatory and pro-angiogenic factor activity, reduce hypoxia, suppress inflammation, promote regeneration, and prevent fibrosis in OSAHS-injured tissues. In this paper, we will describe the pathogenesis of inflammation, oxidative stress, fibrosis and ischemia from the perspective of OSAHS, highlighting the current research progress on MSCs-dependent regulation of OSAHS-related pathology.
