TCs in cell cultures from human non-pregnant/pregnant myometrium after 72 h in culture at first passage. a, e Phase-contrast microscopy depicts cell morphologies very evocative for TCs: small cell body with very long Tps characterized by a moniliform silhouette (alternation of podoms and podomers). Fluorescence microscopy shows CD34 (b, f) and PDGFR-α (c, g)-positive TCs. d, h Double labeling for both markers showing a different expression pattern for PDGFR-α and CD34 in the same TC. Nuclei were stained with DAPI. Bar 50 µm
