Study Notes
Connective Tissue Overview
- Connective tissue consists of cellular and extracellular components that support, bind, and protect other tissues and organs.
- Mesenchymal cells are multipotent stem cells capable of differentiating into different types of connective tissue cells.
- "Multipotent" refers to the ability of these cells to evolve into multiple cell types within a specific lineage.
Functions of Connective Tissue
- Connective tissue plays vital roles in structural support, nutrient storage, immune defense, and serving as a medium for circulation.
- Key immunological defense cells found in connective tissue include macrophages, mast cells, and lymphocytes.
Origin and Development
- Derived from mesenchyme, which is the embryonic tissue primarily from the mesoderm (middle layer of the embryo).
- These cells migrate from the original germ layers, surrounding and penetrating developing organs during embryonic development.
Adult Connective Tissues
- Examples of adult tissues where mesenchymal cells persist include adipose tissue, cartilage, and bone marrow.
- Mesenchymal stem cells reside in niches within these adult connective tissues, providing potential for regeneration.
Components of Connective Tissue
- Composed of cells (such as fibroblasts, adipocytes, and immune cells), fibers (including collagen, elastin, and reticular fibers), and ground substance (the non-cellular material surrounding cells).
- The matrix, made up of ground substance and fibers, is critical for tissue function and structure.
Types of Connective Tissue
- Three major types of connective tissue:
- Loose connective tissue (e.g., areolar tissue)
- Dense connective tissue (e.g., tendons and ligaments)
- Specialized connective tissue (e.g., blood, bone, cartilage)
Cell Types
- Most common cell types include fibroblasts, adipocytes, immune cells (e.g., mast cells and macrophages), and chondrocytes in cartilage.
- Each cell type plays a unique role in tissue integrity, metabolism, and immune response.
