Ce travelled by at least 15 cells per experiment. Speed was calculated as total distance divided by total time. Persistence was estimated by 1317923 the 1480666 ratio on the net distance towards the total distance. Net displacement on the X axis is given by the sum of all displacements around the X axis. Generation of KO cells. In, schematic representation of polycystin-2 gene in WT and pkd2 KO cells. Arrows indicate the position of the oligonucleotides employed to MNS site construct the KO vector and to screen pkd2 KO cells. In, gene position refers to position on the genomic sequence on the gene. Screen for pkd2 KO cells was performed by PCR, and distinct pairs of oligonucleotides have been used to screen for get or loss of signal in KO cells. In, 59 and 39 gene fragments utilized for generation of iplA, mscS, pkd2 and tpc KO cells by homologous recombination. 34540-22-2 Screening was performed precisely in the exact same way for the four KO cell lines. PKD2 and Mechanosensing in Dictyostelium Movie S1 WT cells moving randomly, with no any flow passing by way of the system. Phase-contrast images had been taken each and every 15 sec, through ten min. Size: 160695 mm. Movie S2 WT cells below shear-flow stress. Phase-contrast images had been taken every single 15 sec, in the course of 10 min. Size: 160695 mm. Movie S3 pkd2 KO cells moving randomly, without any flow passing through the system. Phase-contrast photos were taken every 15 sec, in the course of ten min. Size: 160695 mm. Film S4 pkd2 KO cells under shear-flow stress. Phase-contrast images have been taken each and every 15 sec, during ten min. Size: 160695 mm.

Generation of KO cells. In, schematic representation of polycystin-2 gene in WT and pkd2 KO cells. Arrows indicate the position from the oligonucleotides made use of to construct the KO vector and to screen pkd2 KO cells. In, gene position refers to position on the genomic sequence of your gene. Screen for pkd2 KO cells was done by PCR, and distinct pairs of oligonucleotides were employed to screen for gain or loss of signal in KO cells. In, 59 and 39 gene fragments utilized for generation of iplA, mscS, pkd2 and tpc KO cells by homologous recombination.
