Abstract

Insights

Mesenchymal stem cell-derived small extracellular vesicles (MSC-sEV) show promise for cervical cancer treatment by activating the NOTCH pathway, promoting squamous differentiation, and inhibiting cancer cell growth and migration.

Area of Science:

  • Oncology
  • Cell Biology
  • Biotechnology

Background:

  • Cervical cancer is a significant global health concern for women, necessitating novel therapeutic strategies.
  • Current treatments face limitations, driving research into innovative approaches like stem cell-derived therapies.

Purpose of the Study:

  • To investigate the therapeutic potential of small extracellular vesicles derived from human umbilical cord mesenchymal stem cells (MSC-sEV) in cervical cancer.
  • To elucidate the effects of MSC-sEV on cervical cancer cell lines, focusing on squamous differentiation and the NOTCH signaling pathway.

Main Methods:

  • Extraction and identification of MSC-sEV from human umbilical cord-derived mesenchymal stem cells.
  • In vitro assessment of MSC-sEV effects on CaSki (cervical cancer) and HaCaT (keratinocyte) cell lines.
  • Analysis of NOTCH pathway activation, cell growth, proliferation, migration, and squamous differentiation.

Main Results:

  • MSC-sEV, specifically Jagged1 protein, bind to NOTCH1 on cervical cancer cells, activating the NOTCH pathway.
  • MSC-sEV promote squamous differentiation in CaSki cells, inhibiting their growth, proliferation, and migration.
  • MSC-sEV activate the NOTCH pathway in HaCaT cells, enhancing their viability.

Conclusions:

  • MSC-sEV represent a potential novel therapeutic agent for cervical cancer by activating the NOTCH pathway.
  • The mechanism involves promoting squamous differentiation and inhibiting the growth, proliferation, and migration of cervical cancer cells.

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

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...

Notch Signaling Pathway03:14

Notch Signaling Pathway

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...

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
