Age involution of thymus (human) | Stain: Azan. A: Although the adipose tissue in the thymus of a patient of 65 years is predominant it still contains areas of remnants (arrows 1+2) of cortical (2) and medullary portions (1) of the thymus. B+C: Degradation of thymic tissues is less progressed in adults and shows less replacement of... | thymus age; thymus involution; adipose cells; lymphoid tissue | Poja Histology Collection - Lymphatic Tissues and Organs Subset |

 |
Age involution of thymus (human, postpuberal) | Stain: Azan. The size of the thymus is age-dependent, and undergoes a continuous process of involution, starting at postpuberal age. Due to depletion and reduced production of cortical thymocytes, as well as a gradual atrophy of the epithelial cells, the clear distinction between medulla (1) and cor... | thymus age; adipose cells; thymus involution; lymphoid tissue | Poja Histology Collection - Lymphatic Tissues and Organs Subset |

Alveolar cell type II (pneumocyte II) in an alveolus (dog) | Electron microscopy. At (X) the alveolar space, the bulging alveolar cell type II shows the characteristic multilamellar bodies (*, cytosomes) that contain precusor material of surfactant. The lamellar bodies are responsible for the vacuolated appearance of these cells, and they give rise to surfact... | Pneumocyte II; Alveolar cell type II | Poja Histology Collection - Respiratory System Subset |
