研究者发现年老的干细胞是如何增加腹部脂肪的, 有可能导致新的治疗方法。 Researchers discover how aging stem cells increase belly fat, potentially leading to new treatments.

来自希望城市的研究人员已经查明了腰围为什么随着年龄的增长而扩大,将腰围与一种新的成人干细胞联系起来,这种干细胞可以增加脂肪细胞的生产,特别是腹部周围的脂肪细胞的生产。 Researchers from City of Hope have identified why waistlines expand with age, linking it to a new type of adult stem cell that enhances fat cell production, especially around the belly. 研究发现,老化将二二子细胞先天细胞(APCs)转化为活性脂肪生产者,称为承诺的先天脂肪细胞(CP-As),由于一个称为LIFR的信号路径,这种细胞会成倍增加。 The study found that aging transforms adipocyte progenitor cells (APCs) into active fat producers, known as committed preadipocytes (CP-As), which multiply due to a signaling pathway called LIFR. 这一发现可能导致采取新的医疗方法,以减少腹部脂肪和改善老年人的健康。 This discovery could lead to new medical approaches to reduce belly fat and improve health in older adults.
