[Bone morphogenetic protein-4 regulates embryonic tongue morphogenesis].
1Department of Orthodontic, Peking University School and Hospital of Stamotology, Beijing 100081, China.
Summary
Bone Morphogenetic Protein 4 (BMP4) significantly alters embryonic tongue development, leading to shorter, narrower tongues. Its antagonist, Noggin, promotes wider and longer tongue growth, while BMP4 inhibits cell proliferation.
Area of Science:
- Developmental Biology
- Molecular Biology
- Regenerative Medicine
Context:
- Embryonic tongue development is a complex process influenced by various signaling pathways.
- Bone Morphogenetic Protein 4 (BMP4) is a key signaling molecule implicated in embryonic development.
- Understanding BMP4's role is crucial for addressing congenital tongue abnormalities.
Purpose:
- To investigate the specific effects of BMP4 and its antagonist Noggin on the morphogenesis of embryonic rat tongues.
- To analyze the impact of BMP4 on cell proliferation within the developing tongue.
- To quantify morphological changes in response to varying concentrations of BMP4 and Noggin.
Summary:
- Exposure to BMP4 resulted in significantly shortened and narrowed embryonic tongues, altering the typical spatula shape to a more pointed morphology.
- Conversely, treatment with Noggin led to an increase in tongue width and length compared to controls.
- BMP4 application was also found to inhibit cell proliferation in both the epithelial and mesenchymal tissues of the embryonic tongues.
Impact:
- This study elucidates the critical role of BMP4 in regulating embryonic tongue shape and size.
- Findings suggest BMP4 as a potential therapeutic target for conditions involving abnormal tongue development.
- The differential effects of BMP4 and Noggin provide insights into the molecular mechanisms governing craniofacial morphogenesis.

01:51Determination
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...
01:56Gastrulation
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata will form...
01:12The Hyoid Bone
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

02:23Master Transcription Regulators
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...
