TGFB1 and cancer: Immunofluorescence imaging of osteocytes demonstrated that TGF‐β reduced osteocyte primary cilia prevalence and length, in agreement with findings reported in other cell types.[22, 23, 24] Furthermore, conditioned media from each cancer cell line also induced similar changes in cilia expression with shorter cilia and prevalence decreased to 20% (Figure 4; Figure S4, Supporting Information).
