Virtual Slides: Bone, Bone Formation and Joints | Histology Drawings


Introduction

Bone-femur-c.jpg
Endochondral bone.jpg
Our adult skeleton forms from a larger number of developmental elements that are replaced and fuse. In development there are 2 separate signaling pathways for pattern formation and the formation of bone itself. Furthermore bone formation can be divided into 2 specific forms that occur in anatomically different regions. This practical class will describe the development and structure of bone and finish with a study of abnormalities associated with bone.

The image shown to the left shows a histological section through the developing lower limb at the level of a developing joint (knee), surrounding the developing bone are skeletal muscles and connective tissue of the limb.

Bone Structure

Bone-structure.jpg


Terminology

  • Diaphysis - shaft
  • Epiphysis - expanded ends
  • Metaphysis - connecting region (between diaphysis and epiphysial line)
  • Medullary Cavity - (marrow) cavity within the bone.

More? Terms


Compact Bone

  • (dense) no spaces or hollows in the bone matrix visible to the eye.
  • forms the thick-walled tube of the shaft (or diaphysis) of long bones, which surrounds the marrow cavity (or medullary cavity). A thin layer of compact bone also covers the epiphyses of long bones.


Osteocyte
The mature bone-forming cell, which form the cellular component of bone and produce bone matrix. Differentiate from osteoblasts, mesenchymal cells that differentiate to form bone.

Note the osteocytes have cytoplasm extending radially into lacunae - canaliculi.

Bone histology 022.jpg Bone histology 066.jpg



Trabecular Bone

  • (cancellous or spongy bone) consists of delicate bars (spicules) and sheets of bone, trabeculae
  • branch and intersect to form a sponge-like network
  • ends of long bones (or epiphyses) consist mainly of trabecular bone.

Periosteum

Connective tissue covering the surface of bone (except articular surfaces).

Periosteum.jpg

Endosteum

Connective tissue lining inner surface of bone.


Bone Growth

  • Appositional growth occurs at either the periosteum (outer surface), or the endosteum (inner surface).
  • Osteoblasts secrete osteoid, a pre-bone material composed mainly of type I collagen that becomes mineralized.
  • Early bone matrix deposited in development and during repair is woven rather than lamellar in appearance and structure.
  • In development, there are 2 distinct types of bone formation (intramembranous and endochondral)

Bone Cells

Osteoblasts

Mouse osteoblast 01.jpg

  • derive from osteogenic stem cells the osteoprogenitor cells that differentiate to form pre-osteoblast then osteoblasts maturing to an osteocyte
  • osteoprogenitor cells - "resting cell" line the inner and outer surfaces of bone

Osteocytes

  • mature bone-forming cells embedded in lacunae within the bone matrix
  • osteoblasts and osteocytes - secrete organic matrix of bone (osteoid), converted into osteocytes when become embedded in matrix (which calcifies soon after deposition)

Osteoclasts

Mouse osteoclast 01.jpg Osteoclast.jpg Bone remodeling cycle.jpg

  • bone-resorbing multinucleated macrophage-like cells
  • origin- fusion of monocytes or macrophages, Blood macrophage precursor, Attach to bone matrix
  • seal a small segment of extracellular space (between plasma membrane and bone surface), HCl and lysosomes secreted into this space by osteoclasts dissolves calcium phosphate crystals (give bone rigidity and strength)
    • Resorptive bay - (Howship's lacuna) shallow bay lying directly under an osteoclast.
  • do not mistake for megakaryocytes, found in bone marrow not associated with bone matrix.
    • megakaryocytes are also multi-niucleated and form platelets

Bone Marrow

Hematopoietic and stromal cell differentiation
  • red marrow - mainly haematopoietic (myeloid) tissue, newborn has all red marrow
  • yellow marrow - mainly fat cells, found in diaphysis region of long bones
  • stromal cells - all other support cells not involved in haematopoiesis

Chondroblasts and Chondrocytes

  • immature and mature cartilage forming cells located at articular cartilage regions.
  • Interstitial growth - occurs mainly in immature cartilage. Chondroblasts in existing cartilage divide and form small groups of cells (isogenous groups) which produce matrix to become separated from each other by a thin partition of matrix.
  • Appositional growth - occurs also in mature cartilage. Mesenchymal cells surrounding the cartilage in the deep part of the perichondrium (or the chondrogenic layer) differentiate into chondroblasts.

Bone Matrix

The bone matrix has 2 major components.

  • Organic portion composed of mainly collagen Type 1 (about 95%) and amorphous ground substance.
  • Inorganic portion (50% dry weight of the matrix) composed of hydroxyapatite crystals, calcium, phosphorus, bicarbonate, nitrate, Mg, K, Na.
    • storage calcium and phosphate
    • regulate blood calcium levels

Haversian Systems

Bone structure cartoon
  • also called osteons
  • Volkmann's canals - interconnect Haversian systems
Bone histology 001.jpg Bone histology 002.jpg
Low Power (x10) High Power (x20)

Lamellae

  • concentric - surrounding each Haversian System
  • interstitial - bony plates that fill in between the haversian systems.
  • circumferential - layers of bone that underlie the periosteum and endosteum

Cells

  • osteocytes extending cytoplasmic processes into canaliculi

Histology Stains

Alizarin Red

  • an anthraquinone derivative used to identify calcium in tissue sections
  • calcium forms an Alizarin Red S-calcium complex in a chelation process and the end product is also birefringent.
  • reaction can also identify magnesium, manganese, barium, strontium, and iron may interfere
    • these elements usually in too low concentration to interfere with the staining

H&E

  • acronym for hematoxylin and eosin stain
  • hematoxylin - basic dye which colors basophilic structures with blue-purple hue (nucleus, DNA, RNA)
  • eosin Y - acidic alcohol-based which colors eosinophilic structures bright pink (cytoplasm, extracellular matrix, protein)

H&Van Gieson

  • Van Gieson's Stain is a mixture of picric acid and acid fuchsin used for differential staining of collagen and other connective tissue.
    • Nuclei - stains brownish black to black
    • Collagen (fibrous connective tissue) - stains pink or deep red
    • Muscle, Cytoplasm, RBC and Fibrin - stains yellow

Haematoxylin and Eosin
One of the most common staining techniques in pathology and histology. Acronym "H and E" stain. (H&E, HE).


Haematoxylin
  • Stains nuclei blue to dark-blue.
  • Stains the matrix of hyaline cartilage, myxomatous, and mucoid material pale blue.
  • Stains myelin weakly but is not noticeable if combined with eosin stain.
  • combined with Orange G (H & Or. G.) instead of eosin, specifically stains the granules of acidophilic cells of the adenohypophysis (anterior pituitary).
Eosin
  • Stains cytoplasm pink to red; red blood cells are also bright red.
  • Common counterstain to hematoxylin.
  • Stain intensity varies with the formula as well as the fixative.
