苏木精-伊红染色是一种常用的组织切片染色方法。首先，组织切片用苏木精染色，这使细胞核染上深蓝色。接着，用伊红染色，可使胞质和胶原纤维呈现红色。这种染色方法广泛应用于病理学、组织学和解剖学领域，使研究者能够在显微镜下更清晰地观察和区分组织结构，对疾病诊断和研究提供了基本的组织学信息。

Hematoxylin-eosin staining is a commonly used staining method for tissue sections. First, tissue sections are stained with hematoxylin, which stains cell nuclei a dark blue. Next, staining with eosin makes the cytoplasm and collagen fibers appear red. This staining method is widely used in the fields of pathology, histology and anatomy, allowing researchers to more clearly observe and distinguish tissue structures under the microscope, and provides basic histological information for disease diagnosis and research.
