Fig. 4From: An in vitro investigation of telocytes-educated macrophages: morphology, heterocellular junctions, apoptosis and invasion analysisa–c Scanning electron microscopy of the direct co-cultured system at 24 h. TCs displayed oval cell body with long TP. The activated pMACs with irregular shape, abundant fluff-like structures on the surface of the cell membrane was observed. The complex direct heterocellular junction between the activated pMACs and Tp was presumably a certain type of immunological synapse (IS)Back to article page
