somitic การใช้
- This gene also plays a role in the formation of epithelial somitic mesoderm and cardiac mesoderm.
- As it involutes, it converges along the mediolateral axis and extends along the future anterior-posterior axis of the notochordal and somitic mesoderm.
- In contrast, the cells within each somite retain plasticity ( the ability to form any kind of structure ) until relatively late in somitic development.
- BMP4 has been shown to induce the expression of the Msx gene family, which is believed to be part of cartilage formation from somitic mesoderm.
- The Hox genes specify somites as a whole based on their position along the anterior-posterior axis through specifying the pre-somitic mesoderm before somitogenesis occurs.
- Although expression of Shh pathway proteins has not been reported to oscillate in the pre-somitic mesoderm, they are expressed within the pre-somitic mesoderm during somitogenesis.
- Although expression of Shh pathway proteins has not been reported to oscillate in the pre-somitic mesoderm, they are expressed within the pre-somitic mesoderm during somitogenesis.
- Regarding the paraxial mesoderm from which somites form, fate mapping experiments at the blastula stage show pre-somitic mesoderm progenitors at the site of gastrulation, referred to as the primitive streak in some organisms, in regions flanking the organizer.
- For instance, exposure of pre-somitic mesoderm to Bone morphogenetic proteins ( BMPs ) ventralizes the tissue, however " in vivo ", BMP antagonists secreted by the organizer ( such as Noggin and chordin ) prevent this and thus promote the formation of dorsal structures.
- Once the cells of the pre-somitic mesoderm are in place following by cell migration during gastrulation, oscillatory expression of many genes begins in these cells as if regulated by a developmental " clock . " This has led many to conclude that somitogenesis is coordinated by a " clock and wave " mechanism.
- Once the cells of the pre-somitic mesoderm are in place following cell migration during gastrulation, oscillatory expression of many genes begins in these cells as if regulated by a developmental " clock . " As mentioned previously, this has led many to conclude that somitogenesis is coordinated by a " clock and wave " mechanism.
- "' Paraxial mesoderm "', also known as "'presomitic "'or "'somitic mesoderm "'is the area of mesoderm in the tissue running along both sides of the neural tube, which form muscle and the tissues of the back, including connective tissue and the dermis.
