Summary
Umbilical cord scaffolds promote cartilage regeneration in human bone marrow-derived mesenchymal stem cells (hBM-MSCs). These natural biomaterials enhance chondrogenic differentiation compared to commercial scaffolds, offering a promising approach for cartilage tissue engineering.
Area of Science:
- Biomaterials Science
- Regenerative Medicine
- Tissue Engineering
Background:
- Articular cartilage damage has limited self-regeneration due to its avascular nature.
- Current methods for differentiating human bone marrow-derived mesenchymal stem cells (hBM-MSCs) into cartilage yield suboptimal tissue quality.
- Decellularized biological scaffolds show potential for guiding cell behavior in tissue engineering.
Purpose of the Study:
- To investigate the potential of human umbilical cord-derived scaffolds for cartilage tissue engineering.
- To evaluate the chondrogenic induction of hBM-MSCs loaded onto umbilical cord scaffolds compared to gelatin scaffolds.
Main Methods:
- Preparation of human umbilical cord-derived scaffolds.
- Loading hBM-MSCs onto umbilical cord and gelatin scaffolds.
- Assessment of chondrogenic, hypertrophic, and osteogenic marker expression.
Main Results:
- hBM-MSCs cultured on umbilical cord scaffolds exhibited increased expression of chondrogenic markers compared to those on gelatin scaffolds.
- No significant differences were observed in hypertrophic and osteogenic marker expression between the two scaffold types.
- Umbilical cord scaffolds provided a more native cellular environment, promoting cartilage differentiation.
Conclusions:
- Human umbilical cord-derived scaffolds are effective biomaterials for promoting cartilage differentiation of hBM-MSCs.
- These scaffolds offer a promising alternative to commercial materials for cartilage tissue engineering applications.
- The native composition of umbilical cord supports cellular functions crucial for cartilage regeneration.

4.1K
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...

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.

A heat engine is a device used to extract heat from a source and then convert it into mechanical work used for various applications. For example, a steam engine on an old-style train can produce the work needed for driving the train.
Whenever we consider heat engines (and associated devices such as refrigerators and heat pumps), we do not use the standard sign convention for heat and work. For convenience, we assume that the symbols Qh, Qc, and W represent only the amounts of heat transferred...

31.6K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.
