Selected slides from the AACR poster.

Stem cell niche

Niche in tumor - low power not shown in poster (see also high power: AACR_Scan01.jpg)

Stem cell niche

Niche in tumor (Mild intraepithelial neoplasia of uterine cervix) see also high power: AACR_Scan02.jpg

Stem cell niche progenitor cell

Stem cell niche with progenitor cell (Infiltrating carcinoma of uterine cervix - CIS)

Stem cell niche halo

Stem cell niche: Halo formation between inner and outer membrane. (Medullary carcinoma of breast)

Stem cell niche halo

(see also low power: AACR_Scan05.jpg , DSC_1475.jpg) Stem cell niche: Cell in quiescent state; halo formation between inner and outer membrane; niche surrounded by closely attached support cells. (High-grade intraepithelial neoplasia)

cervix - Infiltrating squamous cell carcinoma - Niche with asymmetric division

(see high power 01120001.jpg) Niche surrounded by support cells with one self-renewal daughter cell (arrow) consisting of spheres and one differentiated tumor cell. (Infiltrating squamous cell carcinoma of uterine cervix [2])

cervix - Infiltrating squamous cell carcinoma - Niche with asymmetric division

(See also: DRNEPT1-R01-014.Jpg) Niche surrounded by support cells with one self-renewal daughter cell consisting of spheres and one differentiated tumor cell. (Infiltrating squamous cell carcinoma of uterine cervix [2])

Asymmetric division papillary adenocarcinoma uterine cervix

Asymmetric division: Self-renewal daughter cell and progenitor cell consisting entirely of spheres with uniform luminal diameters. (Papillary adenocarcinoma of uterine cervix [3]) (duplicates: 01120006.jpg

Asymmetric division papillary adenocarcinoma

(see high power: DSC_1470.jpg; see also: 01120007.JPG ) Asymmetric division: Self-renewal daughter cell and progenitor cell consisting entirely of spheres with uniform luminal diameters. (Papillary adenocarcinoma of uterine cervix [3])

Niche self-renewal daughter cell

(see low power: 1459): abandoned niche: may be remains of self renewal cell) Niche with single self-renewal daughter cell. (Papillary carcinoma of urinary bladder)

Epithelial cells G0 G1 G2

Epithelial cells: Complete absence of spheres with the exception of sporadic spheres in tumor cells
