connective tissue
Features
A large amount of extracellular matrix: fiber, matrix, interstitial fluid
The number of cells is small and many types, scattered in the extracellular matrix without polarity.
constitute
Derived from mesenchymal differentiation during embryonic stage
Contains blood vessels and nerve tissue
Classification
Cartilage tissue Bone tissue Blood and lymph
intrinsic connective tissue
Loose connective/cellulite tissue
dense connective tissue
Adipose tissue
reticular tissue
Function: Connection supports nutrient transport, defense and repair
cellulite
cell
Fibroblasts
shape
Often attached to collagen fibers, the outline is often unclear
Large in size, with protrusions, large and oval nuclei, and obvious nucleoli.
The largest number and most important HE stain shows weak basophilic coloration.
Function
Synthesize and secrete collagen, elastin, and proteoglycans
various fibrous matrices that form connective tissue
Engage in trauma repair when entering the dynamic
Macrophages
Derived from monocytes in blood
shape
The pseudopodia extended by LM are irregular in shape, the nucleus is small, dark, oval/round, and the cytoplasm is eosinophilic.
EM has many folds and microvilli, and the cytoplasm contains a large number of lysosomes
Function: phagocytosis, antigen presentation, secretion
Plasma cell
Derived from B lymphocytes
shape
LM
The cells are round or oval, and the nuclei are mostly round on one side of the cell.
Chromatin aggregates under the membrane to form a wheel shape, and the cytoplasm is basophilic.
The EM cytoplasm contains parallel-arranged rough endoplasmic reticulum and a well-developed Golgi apparatus.
Function: Synthesize secreted immune proteins, namely antibodies, and participate in humoral immunity
Mast cells
Distributed around small blood vessels and lymphatic vessels
shape
Cells are round/oval with small, round and centered nuclei.
In the cytoplasm
filled with basophilic granules
heparin
Anticoagulation
neutrophil chemoattractant
Phagocytosis of bacteria
eotaxin
Reduce allergic reactions Sterilize
histamine
Contains leukotrienes
Dilates capillaries causing edema and participates in allergic reactions
fat cells
shape
LM is distributed singly or in groups, with large round/oval cell bodies.
HE staining lipid droplets dissolve → cells become vacuolated
The cytoplasm contains large lipid droplets and the nucleus is squeezed into a meniscus on one side of the cell.
Function: Synthesize and store fat and participate in lipid reactions
undifferentiated mesenchymal cells
Stem cells maintain differentiation potential and participate in repair
leukocyte
derived from blood
extracellular matrix
fiber
Collagen/(new) white fiber
shape
The most numerous light red (HE eosinophilic)
Wave-like branches intertwined into a network
The slices are of different lengths and thicknesses and have different shades of coloring.
LM
Composed of type I and type III collagen
Features: high toughness and strong tensile strength
Elastic/(new)yellow fiber
shape
Smaller quantity, finer, HE colored light red
Difficult to distinguish collagen fibers
LM
Made of microfibrils and elastin
Features: High elasticity
mesh fiber
shape
The smallest quantity, silver dye is brown-black
The fibers are short and thin, with many branches and are interwoven into a network.
PAS reaction is positive
LM
Composed of type III collagen
Function: constitute organ scaffold
matrix
Amorphous sticky gel
Proteoglycans
shape
glycosaminoglycans
Hyaluronic acid is a long-chain macromolecule that forms the backbone
Chondroitin sulfate Keratan sulfate Heparan sulfate Proteoglycan subunit
fibronectin
tissue fluid
Part of the plasma component exuded from the arterial end of capillaries. The body fluid environment that cells rely on to survive.
