Summary
Krüppel-like factor (KLF) 10 regulates chondrocyte hypertrophy in developing skeletons. Suppressing KLF10 may prevent cartilage hypertrophy during stem cell regeneration.
Area of Science:
- Skeletal Biology
- Developmental Biology
- Cell Biology
Background:
- Chondrocyte hypertrophy is crucial for skeletal development.
- Krüppel-like factors (KLFs) are transcription factors with diverse biological roles.
- The specific role of KLF10 in chondrogenesis and skeletal development remains unclear.
Purpose of the Study:
- To elucidate the functional role of Krüppel-like factor (KLF) 10 in modulating chondrocyte hypertrophy.
- To investigate the impact of KLF10 deficiency on skeletal development and mesenchymal stem cell (MSC) differentiation.
Main Methods:
- Analysis of long bone development in KLF10 knockout (KO) mice.
- Characterization of chondrogenesis and osteogenesis in MSCs derived from KLF10 KO mice.
- Assessment of Indian hedgehog (Ihh) expression in the epiphyseal plate.
Main Results:
- KLF10 KO mice exhibited delayed long bone growth and primary ossification center formation.
- Reduced Indian hedgehog expression was observed in the epiphyseal plate of KLF10 KO mice.
- While chondrogenic potential was normal or slightly decreased, hypertrophy and osteogenesis were significantly suppressed in KLF10 KO MSCs.
Conclusions:
- KLF10 acts as a mediator of chondrocyte hypertrophy during skeletal development.
- KLF10 deficiency suppresses chondrocyte hypertrophy and osteogenesis.
- Targeting KLF10 could be a novel strategy for preventing hypertrophy in cartilage regeneration using MSCs.

01:27Growth of Cartilage and Bone Tissue
3.9K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

01:24Bone Formation by Endochondral Ossification
7.8K
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...

01:17Hormones and Bone Tissue
3.6K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:40Bone Remodeling
40.1K
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.

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

01:31Osteoclasts in Bone Remodeling
3.7K
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...
