Using Real-Time Cell Metabolic Flux Analyzer to Monitor Osteoblast Bioenergetics
Published on: March 1, 2022
Summary
Childhood cancer treatments can harm bone health, leading to low bone mineral density (BMD) and increased fracture risk. Long-term effects, especially in non-ALL survivors, require further study and endocrine monitoring.
Area of Science:
- Pediatric Oncology
- Endocrinology
- Bone Metabolism
Background:
- Childhood cancer treatments pose significant risks to bone health through direct and indirect mechanisms.
- Cranial irradiation in acute lymphoblastic leukemia (ALL) survivors is linked to growth hormone deficiency and reduced bone mineral density (BMD).
- Current chemotherapy protocols can cause temporary BMD decreases and elevate fracture risk during treatment.
Purpose of the Study:
- To evaluate the impact of childhood cancer and its treatments on bone health.
- To identify risk factors associated with decreased BMD in pediatric cancer survivors.
- To highlight the need for long-term monitoring and management of bone health in these patients.
Main Methods:
- Review of clinical outcome studies focusing on pediatric cancer survivors.
- Analysis of factors influencing bone mineral density (BMD) such as treatment protocols, medication dosage, and patient demographics.
- Examination of BMD outcomes in survivors of acute lymphoblastic leukemia (ALL) and other childhood cancers.
Main Results:
- High-dose cranial irradiation (≥24 Gy) is associated with growth hormone deficiency and low BMD.
- BMD decreases during chemotherapy, with potential long-term reductions in lumbar spine trabecular BMD.
- Risk factors for low BMD include high-dose methotrexate, cumulative glucocorticoids, male gender, and low physical activity.
- Survivors of non-ALL cancers (brain/bone tumors, bone marrow transplants) also face a high risk of osteopenia.
Conclusions:
- Childhood cancer survivors are at significant risk for long-term bone health issues, including osteopenia.
- Long-term follow-up is crucial for identifying and treating endocrine abnormalities affecting bone health.
- Further research is needed to understand the long-term fracture risk implications in survivors.

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...

01:29Bone 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...

01:30Bone Cells and Tissue
Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the periosteum and...

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...
