Obtaining Primary Osteocytes Through Murine Calvarial Fractionation of GFP-Expressing Osteocytes
Published on: June 2, 2020
Summary
Osteocytic activity drives bone resorption in vertebrates. This study confirms this process in Upper Cretaceous reptile bone fragments from Alberta, Canada.
Area of Science:
- Paleontology
- Vertebrate Biology
- Bone Histology
Background:
- Osteocytic osteolysis is a known mechanism of bone resorption across vertebrate classes.
- Understanding the evolutionary history of bone remodeling provides insights into skeletal adaptation.
Observation:
- Bone resorption via osteocytic activity was identified in fossilized long bone fragments.
- These fragments belong to an unidentified reptile species.
- The fossils were recovered from an Upper Cretaceous geological formation.
Findings:
- The study provides direct evidence of osteocytic bone resorption in a Cretaceous reptile.
- This finding extends the known fossil record of this bone remodeling mechanism.
Implications:
- Confirms the ancient presence and function of osteocytic osteolysis in reptilian skeletal biology.
- Contributes to the understanding of bone remodeling evolution in dinosaurs and related species.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:31Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
01:18The Bone Matrix
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in acid or...
01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:24Bone Formation by Endochondral Ossification
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...
