Insights

Disintegrin and metalloprotease 28 (ADAM28) is involved in tooth development. Researchers developed an antibody to study ADAM28 expression in dental cells, revealing its role in regulating odontogenic mesenchymal cells.

Area of Science:

  • Biochemistry
  • Developmental Biology
  • Cell Biology

Background:

  • Disintegrin and metalloprotease (ADAM) proteins are crucial for various biological processes, including development and cell signaling.
  • ADAM28 is a recently identified member of the ADAM family with autocatalytic activity, and its role in tooth development was previously unexplored.

Purpose of the Study:

  • To investigate the expression and localization of ADAM28 during tooth development.
  • To explore the potential role of ADAM28 in regulating human dental mesenchymal and epithelial cells.

Main Methods:

  • Construction and expression of a recombinant glutathione S-transferase-ADAM28 fusion protein.
  • Production and validation of a polyclonal antibody against ADAM28 using Western blot and ELISA.
  • Detection of ADAM28 expression in tooth germ and various human dental cells via immunohistochemistry and RT-PCR.

Main Results:

  • The prokaryotic expression vector for ADAM28 was successfully constructed, yielding a purified fusion protein.
  • A specific and high-titer polyclonal antibody against ADAM28 was generated.
  • ADAM28 was found to be expressed at different levels during all stages of tooth germ development and at the transcriptional level in multiple human dental cell types.

Conclusions:

  • ADAM28 is expressed throughout tooth germ development and in various dental cell types.
  • ADAM28 likely plays a significant role in tooth development and the regulation of odontogenic mesenchymal cells.
  • These findings suggest potential interactions between ADAM28, epithelium, and mesenchyme in regulating tooth formation.

Teeth01:15

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy01:21

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Determination01:51

Determination

During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In contrast, determination...
Hormones and Bone Tissue01:17

Hormones 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...
