Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.6K
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 Disorders

6.3K
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...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.9K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Compact Bone01:27

Compact Bone

18.7K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Spongy Bone01:09

Spongy Bone

9.8K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

    Area of Science:

    • Genetics
    • Pediatrics
    • Bone Biology

    Background:

    • Osteopetrosis is a rare genetic bone disorder characterized by osteoclast dysfunction, resulting in dense, fragile bones.
    • Autosomal recessive forms are typically severe, with early onset and poor prognosis.

    Observation:

    • A young boy presented with asymptomatic autosomal recessive osteopetrosis.
    • Genetic studies identified a specific mutation in the TCIRG1 gene as the cause.

    Findings:

    • The mutation's location in the TCIRG1 gene correlated with the patient's asymptomatic status.
    • The patient's survival beyond the typical age of 2-3 years for this condition was noted.

    Implications:

    • This case highlights the importance of genotype-phenotype correlations in osteopetrosis.
    • Understanding specific mutations may lead to improved prognostication and personalized treatment strategies for rare genetic disorders.
