The bone marrow landscape consists of specialized and stem/progenitor cells, which coordinate important tissue-related and systemic physiological features. Within the marrow cavity, stem/progenitor and differentiated hematopoietic and skeletal cells congregate into dynamic functional assemblies throughout specific anatomical regions, termed niches. There is a need for better understanding of the bone marrow microareas, through exploration of the intramural physical and molecular interactions of the distinctive cell populations. The elective liaisons established among the mesenchymal/stromal stem cell and hematopoietic stem cell lineage trees play a key role in orchestrating the stem/mature cell behavior and customized hierarchies within bone marrow cell populations. Recently, the autophagic apparatus has been discovered to be an important feature of bone marrow homeostasis. Autophagy-related factors involved in the labyrinthic and highly dynamic bone marrow workshop redesign the niche framework by coordinating the operational schedule of pluripotent stem and mature cells. The following report summarizes the most recent breakthroughs in our understanding of the intramural relationships between bone marrow cells and key autophagic mediators. Doubtless, the consideration of the autophagy-related and unrelated functions of main players, such as p62, Atg7, Atg5, and Beclin-1 remains a compelling task to thoroughly understand the complex relations between the heterogenic cell types that populate bone marrow.

通过用于骨髓干/成熟细胞调节的新镜片的原型自噬参与者

骨髓景观由特化细胞和干/祖细胞组成,它们协调重要的组织相关和全身生理特征。在骨髓腔内,干细胞/祖细胞和分化的造血细胞和骨骼细胞在整个特定解剖区域聚集成动态功能组件,称为壁龛。通过探索不同细胞群的壁内物理和分子相互作用,需要更好地了解骨髓微区。在间充质/基质干细胞和造血干细胞谱系树之间建立的选择性联络在协调干/成熟细胞行为和骨髓细胞群内的定制层次结构方面起着关键作用。最近,自噬器官已被发现是骨髓稳态的一个重要特征。迷宫和高动态骨髓研讨会中涉及的自噬相关因素通过协调多能干细胞和成熟细胞的操作时间表重新设计了生态位框架。以下报告总结了我们对骨髓细胞与关键自噬介质之间的壁内关系的理解的最新突破。毫无疑问,考虑主要参与者(如 p62、Atg7、Atg5 和 Beclin-1)的自噬相关和无关功能仍然是一项引人注目的任务,以彻底了解填充骨髓的异源细胞类型之间的复杂关系。迷宫和高动态骨髓研讨会中涉及的自噬相关因素通过协调多能干细胞和成熟细胞的操作时间表重新设计了生态位框架。以下报告总结了我们对骨髓细胞与关键自噬介质之间的壁内关系的理解的最新突破。毫无疑问,考虑主要参与者(如 p62、Atg7、Atg5 和 Beclin-1)的自噬相关和无关功能仍然是一项引人注目的任务,以彻底了解填充骨髓的异源细胞类型之间的复杂关系。迷宫和高动态骨髓研讨会中涉及的自噬相关因素通过协调多能干细胞和成熟细胞的操作时间表重新设计了生态位框架。以下报告总结了我们对骨髓细胞与关键自噬介质之间的壁内关系的理解的最新突破。毫无疑问,考虑主要参与者(如 p62、Atg7、Atg5 和 Beclin-1)的自噬相关和无关功能仍然是一项引人注目的任务,以彻底了解填充骨髓的异源细胞类型之间的复杂关系。以下报告总结了我们对骨髓细胞与关键自噬介质之间的壁内关系的理解的最新突破。毫无疑问,考虑主要参与者(如 p62、Atg7、Atg5 和 Beclin-1)的自噬相关和无关功能仍然是一项引人注目的任务,以彻底了解填充骨髓的异源细胞类型之间的复杂关系。以下报告总结了我们对骨髓细胞与关键自噬介质之间的壁内关系的理解的最新突破。毫无疑问,考虑主要参与者(如 p62、Atg7、Atg5 和 Beclin-1)的自噬相关和无关功能仍然是一项引人注目的任务,以彻底了解填充骨髓的异源细胞类型之间的复杂关系。
