Figure 2From: Small SSEA-4-positive cells from human ovarian cell cultures: related to embryonic stem cells and germinal lineage? Small, round, yellow-coloured cells with diameters of up to 4 μm – putative stem cells – forming cell colonies or appearing as single cells. In ovarian (O), testicular (T) and early human embryonic stem (E) cell cultures after thawing, under an inverted microscope. Scale bars: 50 μm and 10 μm.Back to article page
