Placing Growth Factor-Coated Beads on Early Stage Chicken Embryos
Published on: October 1, 2007
Summary
Polypeptide growth factors regulate animal cell proliferation and differentiation during early embryogenesis. Embryonic cells exhibit resistance to malignant transformation, suggesting potential for novel anti-cancer therapies.
Area of Science:
- Developmental Biology
- Cell Biology
- Cancer Research
Background:
- Polypeptide growth factors are crucial for animal cell development.
- Embryonic cells possess unique sensitivities to these regulatory factors.
- Proto-oncogene products are present in embryonic cells at levels similar to transformed cells.
Purpose of the Study:
- To systematically review data on polypeptide growth factors in animal embryogenesis.
- To investigate the regulatory effects of growth factors on embryonic cells.
- To explore the potential of embryonic cells in cancer research.
Main Methods:
- Systematic literature review of polypeptide growth factors and embryonic cell sensitivity.
- Analysis of data on transforming growth factors and proto-oncogene products in embryonic cells.
- Evaluation of the influence of the embryonic microenvironment on tumor cells.
Main Results:
- Growth factors play a key role in controlling cell proliferation and differentiation in early embryonic stages.
- Embryonic cells, despite high proto-oncogene levels, do not undergo malignant growth.
- The embryonic microenvironment demonstrates an antitransforming effect on tumor cells.
Conclusions:
- Embryonic cells have inherent mechanisms controlling proliferation and differentiation.
- Embryonic cells possess resistance to malignant transformation.
- Understanding the 'normalizing' effect of embryonic cells could lead to new cancer suppression strategies.

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...
02:33Hedgehog 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...
02:38Mitogens and the Cell Cycle
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
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...
01:16TGF - 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 are of three kinds RI, RII, and RIII. The RI...
01:24Methods of Nuclear Reprogramming
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for injury repair.
