Osteoarthritis (OA) is a disease of an entire synovial joint characterized by clinical symptoms and distortion of joint tissues, including cartilage, muscles, ligaments, and bone. Although OA is a disease of all joint tissues, it is a defined accessible compartment and is thus amenable to topical surgical and regenerative therapies, including stem cells. All tissues arise from stem progenitor cells, and the relative capacity of different cellular compartments, and different individuals, to renew tissues into adulthood may be important in the onset of many different degenerative diseases. OA is driven by both mechanical and inflammatory factors, but how these factors affect the proliferation and differentiation of cells into cartilage in vivo is largely unknown. Indeed, our very basic understanding of the physiological cellular kinetics and biology of the stem‐progenitor cell unit of the articular cartilage, and how this is influenced by mechano‐inflammatory injury, is largely unknown. OA seems, rather deceptively, to be the low‐hanging fruit for stem cell therapy. Without the basic understanding of the stem cell and progenitor unit that generate and maintain articular cartilage in vivo, we will continue to waste opportunities to both prevent and manage this disease. In this review, we discuss the biology of chondrogenesis, the stem cell populations that support articular cartilage in health and disease, and future opportunities afforded through the translation of basic articular chondrocyte stem cell biology into new clinical therapies.

骨关节炎的干细胞定向疗法:承诺和实践:简明评论

骨关节炎 (OA) 是一种整个滑膜关节的疾病,其特征是临床症状和关节组织变形,包括软骨、肌肉、韧带和骨骼。虽然 OA 是一种所有关节组织的疾病,但它是一个明确的可及部位,因此适合局部手术和再生疗法,包括干细胞。所有组织都来自干祖细胞,不同细胞区室和不同个体将组织更新到成年的相对能力在许多不同的退行性疾病的发病中可能很重要。OA 由机械和炎症因素共同驱动,但这些因素如何影响细胞在体内增殖和分化为软骨,在很大程度上是未知的。确实,我们对关节软骨干祖细胞单位的生理细胞动力学和生物学的基本了解,以及这如何受到机械炎症损伤的影响,在很大程度上是未知的。OA 似乎是干细胞疗法的低垂果实,颇具欺骗性。如果对在体内产生和维持关节软骨的干细胞和祖细胞没有基本的了解,我们将继续浪费预防和管理这种疾病的机会。在这篇综述中,我们讨论了软骨发生的生物学、在健康和疾病中支持关节软骨的干细胞群,以及通过将基本关节软骨细胞干细胞生物学转化为新的临床疗法所提供的未来机会。以及这如何受到机械炎症损伤的影响,在很大程度上是未知的。OA 似乎是干细胞疗法的低垂果实,颇具欺骗性。如果对在体内产生和维持关节软骨的干细胞和祖细胞没有基本的了解,我们将继续浪费预防和管理这种疾病的机会。在这篇综述中,我们讨论了软骨发生的生物学、在健康和疾病中支持关节软骨的干细胞群,以及通过将基本关节软骨细胞干细胞生物学转化为新的临床疗法所提供的未来机会。以及这如何受到机械炎症损伤的影响,在很大程度上是未知的。OA 似乎是干细胞疗法的低垂果实,颇具欺骗性。如果对在体内产生和维持关节软骨的干细胞和祖细胞没有基本的了解,我们将继续浪费预防和管理这种疾病的机会。在这篇综述中,我们讨论了软骨发生的生物学、在健康和疾病中支持关节软骨的干细胞群,以及通过将基本关节软骨细胞干细胞生物学转化为新的临床疗法所提供的未来机会。如果对在体内产生和维持关节软骨的干细胞和祖细胞没有基本的了解,我们将继续浪费预防和管理这种疾病的机会。在这篇综述中,我们讨论了软骨发生的生物学、在健康和疾病中支持关节软骨的干细胞群,以及通过将基本关节软骨细胞干细胞生物学转化为新的临床疗法所提供的未来机会。如果对在体内产生和维持关节软骨的干细胞和祖细胞没有基本的了解,我们将继续浪费预防和管理这种疾病的机会。在这篇综述中,我们讨论了软骨发生的生物学、在健康和疾病中支持关节软骨的干细胞群,以及通过将基本关节软骨细胞干细胞生物学转化为新的临床疗法所提供的未来机会。
