Abstract:
Growth factors and their receptors are known to send at times contradictory signals, such as proliferation or differentiation. Recent developments in our knowledge of growth factor receptors and their signaling pathways have clarified the basis for this puzzling behavior. Separate domains of a receptor and/or the availability of specific substrates determine the fate of a cell stimulated by the same growth factor. In some models, the difference between malignant transformation and differentiation (leading to cell death) may depend on the presence or absence of a single agonist or antagonist molecule. The type 1 insulin-like growth factor receptor will serve as the paradigm for this review. J. Cell. Biochem. Suppls. 32/33:68-75, 1999.

Cancers Originate from Somatic Mutations in a Single Cell
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
