The parathyroid glands (PTGs) regulate calcium metabolism by secreting parathyroid hormone (PTH). Patients with hypoparathyroidism require lifelong replacement therapy, which is associated with risks of chronic kidney disease, bone fractures, and a reduced quality of life. Generating PTGs from pluripotent stem cells (PSCs) offers a potential regenerative therapy for this condition. This review first explains PTG organogenesis, followed by an overview of both in vitro and in vivo approaches to PTG generation. In vitro studies have successfully induced PTH-expressing parathyroid cells from human PSCs. However, challenges remain, particularly in achieving sufficient PTH secretion and functional efficacy in vivo. Meanwhile, an in vivo organ generation technique known as blastocyst complementation has successfully produced functional PTGs in rodents. However, whether this technology can be applied using human PSCs and animal embryos remains unclear. Pluripotent stem cell-derived PTGs hold promise for both clinical applications and basic research, but further advancements will be necessary to overcome existing challenges in this field.
甲状旁腺通过分泌甲状旁腺激素(PTH)来调节钙代谢。甲状旁腺功能减退症患者需要终身替代治疗,这与慢性肾病、骨折风险以及生活质量下降有关。从多能干细胞(PSC)生成甲状旁腺为这种疾病提供了一种潜在的再生疗法。本综述首先解释甲状旁腺的器官发生,接着概述体外和体内生成甲状旁腺的方法。体外研究已成功从人多能干细胞诱导出表达PTH的甲状旁腺细胞。然而,挑战依然存在,尤其是在体内实现足够的PTH分泌和功能功效方面。同时,一种称为囊胚互补的体内器官生成技术已成功在啮齿动物中产生功能性甲状旁腺。然而,该技术能否用人多能干细胞和动物胚胎来应用仍不清楚。多能干细胞衍生的甲状旁腺在临床应用和基础研究方面都有前景,但要克服该领域现有的挑战还需要进一步进展。
