Histology of Thyroid

Thyroid gland consists of colloid follicles which are lined by cuboid epithelial cells secreting the thyroid hormones, triiodothyronine (T3) and thyroxine (T4). Between the follicles is the interstitial space, containing the blood vessels and the parafolliclar (C) cells responsible for the secretion  of calcitonin.

Hematoxylin and Eosin stain

HE stain is a popular staining method in histology. Its a combination of two dyes the basic dye (hematoxylin) and the alcohol-based dye (eosin). In an HE stain you will usually see both eosinophilia and basophilia the nuclei of cells basophilic (blue), while eosinophilia is typical of cytoplasmic constituents (pink). Xylene, alcohols, distilled water are also required.

MHC genes and molecules

The imune system MHC class I and II molecules and the genes that encode their synthesis are showed in this video, including an illustration of the MHC gene locus and an illustration of the MHC molecular structure.The distribution of the MHC molecules on the cells is also illustrated.

NEJM - Repositioning Dislocated Temporomandibular Joints
