Cancer is a highly heterogeneous disease 1. Distinct oncogenic networks 2. Distinct tumor subtypes due to different cell of origin (and transforming oncogenic networks) 3. Hierarchical organization with Cancer Stem cells (CSC)/ Tumor initiating cells (TICs) capable of self-renewal and tumorigenicity at its apex, and non-TICs which were derived from TICs but have lost their tumorigenic potential forming tumor bulk 4. Clonal evolution.

<strong>Cancer</strong> is a highly heterogeneous disease<br />

1. Distinct oncogenic networks<br />

2. Distinct tumor subtypes due to different cell of origin<br />

(<strong>and</strong> transforming oncogenic networks)<br />

3. Hierarchical organization with <strong>Cancer</strong> <strong>Stem</strong> cells (CSC)/<br />

<strong>Tumor</strong> initiating cells (TICs) capable of self-renewal <strong>and</strong><br />

tumorigenicity at its apex, <strong>and</strong> non-TICs which were derived from<br />

TICs but have lost their tumorigenic potential forming tumor bulk<br />

4. Clonal evolution.
