lacZ has several important applications in histology: 1. Gene Expression Studies: By linking lacZ to specific promoters, researchers can study the spatial and temporal expression of genes. 2. Cell Lineage Tracing: lacZ can be used to trace the lineage of cells during development or in response to various treatments. 3. Mutagenesis Studies: Researchers can use lacZ to identify and characterize mutations that affect gene expression. 4. Tissue-specific Expression: lacZ allows for the study of tissue-specific gene expression patterns in transgenic animals.
