硬脑膜/颅缝间充质干细胞对颅骨发育的影响

Effects of dural/cranial suture mesenchymal stem cells on cranial bone development

颅缝复合体由具有间充质的纤维组织、成骨前沿、下面的硬脑膜和上覆的骨膜组成。硬脑膜是一层保护大脑和脊髓的纤维结缔组织,拥有血管和淋巴管,对早期发育过程中颅骨成骨的进展,后期颅骨的形态和颅缝状态十分重要。颅缝间充质干细胞主要存在于颅缝中,具有增殖、分化为成骨细胞、生成颅骨和增强颅骨损伤后修复的能力。了解颅缝间充质干细胞与硬脑膜的作用机制,对颅骨生长发育和颅脑疾病的治疗非常重要。该文对硬脑膜和颅缝间充质干细胞在颅骨发育中的机制进行综述。

The cranial suture complex is made up of fibrous tissue with mesenchyme,an osteogenic front,the dura mater beneath,and an overlying periosteum.The dura mater is a layer of fibrous connective tissue that protects the brain and spinal cord,containing blood and lymphatic vessels.It is important for the progression of cranial osteogenesis during early development,as well as the cranial morphology and the state of the cranial suture later in life.Cranial suture mesenchymal stem cells are primarily found in the cranial suture and can proliferate,differentiate into osteoblasts,generate cranial bone,and aid in the repair of cranial bone after injury.Understanding how cranial suture mesenchymal stem cells interact with the dura mater is critical for cranial growth and development,as well as the treatment of cranial diseases.This article reviews the roles of dura mater and cranial suture mesenchymal stem cells in cranial bone formation.
