Breast cancer stem cell population in different molecular subtypes of breast cancer.
Background: Breast cancer heterogeneity is well documented and to some extent is attributed to the presence of cancer stem cells (CSCs). Breast cancer stem cells are identified by the presence of cell surface molecule CD44 and absence of CD24.
Methods: In the present study a flowcytometric analysis was done to study the expression distribution of CSC phenotype of CD44+/CD24-/low, among different molecular subtypes of breast cancer and to find a correlation with clinicopathological features.
Results: CSCs were observed in all the molecular subtypes of breast cancer. The highest population of CSCs was noted in luminal B (3.4%), followed by TNBC (1.7%), and Her-2 subtype (1.6%). The least number of CD44+/CD24- cells were seen in Luminal A subgroup (1.3%).
Conclusion: Existence of cancer stem cells in all the subtypes may suggest the possibility of failure of current therapies in treatment of patients.
期刊介绍：
The recent expansion of work in the field of breast cancer inevitably will hasten discoveries that will have impact on patient outcome. The breadth of this research that spans basic science, clinical medicine, epidemiology, and public policy poses difficulties for investigators. Not only is it necessary to be facile in comprehending ideas from many disciplines, but also important to understand the public implications of these discoveries. Breast Disease publishes review issues devoted to an in-depth analysis of the scientific and public implications of recent research on a specific problem in breast cancer. Thus, the reviews will not only discuss recent discoveries but will also reflect on their impact in breast cancer research or clinical management.
