Notch Signaling Pathway03:14

Notch Signaling Pathway

6.7K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

4.3K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Growth of Cartilage and Bone Tissue

4.4K
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...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

2.5K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Bone Cells and Tissue01:30

Bone Cells and Tissue

8.8K
Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the...

Neurulation01:30

Neurulation

46.6K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Area of Science:

  • Oncology
  • Radiology
  • Pathology

Background:

  • Benign notochordal cell tumors (TBCN) are rare lesions originating from notochordal remnants within the axial skeleton.
  • TBCN often present asymptomatically and can be radiologically misidentified as other benign bone lesions or, if symptomatic, misdiagnosed as malignant tumors.

Observation:

  • A case study of a 50-year-old woman with a sacral lesion initially detected by MRI.
  • The lesion was not clearly discernible on CT, necessitating the use of MRI anatomical references for biopsy planning.

Findings:

  • Accurate diagnosis of TBCN requires careful integration of imaging modalities and pathological examination.
  • CT-guided biopsy planning, utilizing MRI references, was crucial for obtaining diagnostic tissue.
  • Radio-pathological correlation proved determinant in achieving a definitive diagnosis.

Implications:

  • This case underscores the diagnostic difficulties associated with TBCN, particularly differentiating them from more aggressive bone pathologies.
  • Emphasizes the critical role of meticulous pre-procedural planning and multidisciplinary correlation in diagnosing rare bone tumors.
  • Highlights the need for increased awareness among radiologists and pathologists regarding TBCN presentation and diagnostic pathways.
