National repositories in histology typically store a variety of materials, including: 1. Tissue Samples: Fresh, frozen, or fixed tissue samples from various species. 2. Histological Slides: Prepared slides stained with specific dyes to highlight different cellular components. 3. Digital Images: High-resolution images of histological slides that can be accessed remotely. 4. Metadata: Detailed information about each sample, including its origin, preparation method, and any associated clinical data.
