WebIn both transition zone and distal pericytes, membrane potential at low inlet pressure (20 mmHg) was approximately −40 mV and was depolarized to approximately −30 mV by an increase in pressure to 80 mmHg. The magnitude of whole-cell VDCC currents in freshly isolated pericytes was approximately half that measured in isolated SMCs. WebIn contrast to its suppressive role in tumour cells and CAFs, 44 TCF21 promoted phenotypical transition of TPCs into matrix–pericytes, which facilitated the haematogenous metastasis of CRC. The distinct functions of TCF21 in TPCs in haematogenous metastasis may be caused by the different methylation levels of the TCF21 .
