Dual labelling of High Grade (HG) ovarian tumor with CD44 and KI67: Panel comprises of (a-d) OSE layer and (e-h) cortex [C] of which (a, e) CD44, Alexa fluor 488, (b, f) KI67, Alexa fluor 568, (c, g) DAPI and (d, h) were merge composites. CD44⁺ cells situated just below OSE layer expressed KI67. Some KI67⁺ cells were prominently visible in cortex. Nuclear as well as cytoplasmic KI67⁺ cells were visible in cortex. White asterisk = CD44⁻ cells, Blue asterisk denotes cytoplasmic KI67. Tiny spherical (VSELs-like) stem cells were indicated by yellow dotted square. White scale bar = 50 μm, blue scale bar = 10 μm, yellow scale bar = 10 μm (D) and green scale bar = 5 μm (D, H)
