Notochord induce neural tube
WebNational Center for Biotechnology Information WebJul 24, 2024 · In our zebrafish model, overexpressing of N1aICD specifically in osteoblasts induced high bone density and caused thicker spinal bones and narrower neural/hemal canals in a gender-specific manner. We hypothesized that different sex hormones might regulate Notch signaling in osteoblastic cells regarding osteoblastic differentiation.

WebIt is distinct from the mesoderm underneath the neural tube, which is called the chordamesoderm that becomes the notochord. The paraxial mesoderm is initially called the “segmental plate” in the chick embryo or the “unsegmented mesoderm” in other vertebrates. WebThe remaining cells in the center form the neural plate, which will go on to form the nervous system. Immediately beneath the neural plate is a rod-shaped mesodermal structure called the notochord. The notochord signals the neural plate cells to fold over to form a tube called the neural tube, as illustrated below. During later development, the ...

WebJun 30, 2024 · Neural tube defects (NTDs) are the second most common structural birth defect. Senescence, a state of permanent cell cycle arrest, occurs only after neural tube closure. Maternal diabetes–induced NTDs are severe diabetic complications that lead to infant mortality or lifelong morbidity and may be linked to premature senescence.
