Figure 2From: Potential of primary kidney cells for somatic cell nuclear transfer mediated transgenesis in pigMorphology of different primary pig cell lines after several passages. Porcine kidney cells (PKCm and PKC2109), fetal fibroblasts (PFF26) and ear fibroblasts (PEF0110) showed all a more or less heterogeneous composition. In all primary cell lines the morphology changed from smaller and round-shaped in early passage (P2) to larger and long spindle-shaped cells in later passage (P13). Scale bar = 100 μm.Back to article page
