WebThe second type of structure, called the 9 + 0 structure, is found in nonmotile cilia without central-pair MTs. Mouse NIH3T3 fibroblast cultured cell also has a single cilium called primary cilium (Fig. 5.1.2 E and F). Nonmotile cilia function as a cellular antenna to regulate signaling pathways and maintain cell state.
