人体中的细胞数量达数万亿，并且具有各种形状和大小。这些微小结构是生物体的基本单元。细胞包括组织，组织包括器官，器官形成器官系统，器官系统在生物体中一起工作。体内有数百种不同类型的细胞，细胞结构非常适合它所发挥的作用。例如，消化系统的细胞在结构和功能上与骨骼系统的细胞不同。无论差异如何，身体的细胞直接或间接地依赖于彼此，以保持身体作为一个单元运作。以下是体内不同类型细胞的实例。干细胞是身体的独特细胞，因为它们是非特化的，并且具有发育成特定器官的特化细胞或发育成组织的能力。干细胞能够分裂和复制多次，以补充和修复组织。在干细胞研究领域，科学家们正试图利用干细胞的更新特性，利用干细胞产生细胞进行组织修复，器官移植和治疗疾病。

The number of cells in the human body is trillions and has various shapes and sizes. These tiny structures are the basic unit of the organism. Cells include tissues, tissues including organs, organs forming organ systems, and organ systems working together in organisms. There are hundreds of different types of cells in the body, and the cell structure is very suitable for its role. For example, cells of the digestive system are structurally and functionally distinct from cells of the skeletal system. Regardless of the difference, the cells of the body depend directly or indirectly on each other to keep the body functioning as a unit. The following are examples of different types of cells in the body. Stem cells are unique cells of the body because they are non-specialized and have the ability to develop specialized cells into specific organs or to develop into tissues. Stem cells are able to divide and replicate multiple times to replenish and repair tissue. In the field of stem cell research, scientists are trying to use the regenerative properties of stem cells to use stem cells to produce cells for tissue repair, organ transplantation and disease treatment.m
