Abstract:
Cancer stem cells (CSCs) are hypothesized to be the main culprit of lung cancer progression. Clinicopathological significance of stem cell markers CD133 and ALDH1 in a large group of lung cancer patients was evaluated. ALDH1 and CD133 had higher expression levels in the NSCLC compared to the SCLC. Over-expression of both ALDH1 and CD133 markers was exclusively found in SCC and ADC. Low level of ALDH1 expression was strongly correlated with poor differentiation in ADC cases. Thus, ALDH1(high)/CD133(high) phenotype can be considered as a CSC marker in some lung cancer subtypes.

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:...
