Summary
This review explores dual-function scaffolds that promote bone healing by enhancing both blood vessel formation (angiogenesis) and bone cell development (osteogenesis), including cartilage formation. These scaffolds are crucial for effective bone regeneration.
Area of Science:
- Biomaterials Science
- Regenerative Medicine
- Tissue Engineering
Background:
- Bone fracture healing involves complex, overlapping stages of inflammation, angiogenesis, and osteogenesis.
- Bone tissue engineering aims to improve bone regeneration by addressing vasculature and osteogenic differentiation.
- Current strategies utilize scaffolds to promote both osteogenesis and angiogenesis.
Purpose of the Study:
- To review major studies on dual-functioning scaffolds for promoting coupled osteogenesis and angiogenesis in bone regeneration.
- To classify scaffolds based on their structural and functional components influencing dual functionality.
- To discuss the role of physico-chemical stimuli and cartilage formation in enhancing bone regeneration.
Main Methods:
- Classification of scaffolds into four types based on structural and functional components.
- Analysis of dual delivery and single delivery systems for osteoinductive and angioinductive factors.
- Review of studies on physico-chemical stimuli and cartilage formation in bone regeneration.
Main Results:
- Scaffolds can achieve dual functionality through structural components or loaded cargo.
- Different scaffold types (dual/single delivery, osteoconductive, osteoconductive/angioconductive) facilitate combined osteogenesis and angiogenesis.
- Synergistic effects of physico-chemical stimuli enhance simultaneous angiogenesis and osteogenesis.
Conclusions:
- Dual-functioning scaffolds are a promising approach for bone regeneration.
- Scaffold design, including material composition and delivery systems, is critical for success.
- Further research into cartilage formation as a mediator in bone regeneration is warranted.

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...

01:17Hormones and Bone Tissue

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...

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...

Bone tissue forms the internal skeleton of vertebrate animals, providing structure to the body.
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts—...

Epithelial tissues are large sheets of cells covering all of the surfaces of the body. These surfaces can be internal or external, for example, skin, airways, the digestive tract, the urinary system, and the reproductive system. Hollow organs and body cavities that do not connect to the body's exterior, including blood vessels and serous membranes, are lined by epithelial tissue known as the endothelium.

Connective tissues perform a broad range of functions in the body. Their primary function is to connect and link different tissues in the body and act as packaging material between tissues. The areolar tissue, a connective tissue prototype, commonly cements various tissue types in diverse body organs. In contrast, adipose tissue cushions internal organs while insulating the body from heat loss.
Hard connective tissues, such as bones and cartilage, provide structure and support to the body.
