The primers that we used were summarized in Supplemental table S1. The amplicons were subcloned into TOPO vectors (life technologies). DIG or fluorescein labeled RNA probes were synthesised by T7 and sp6 RNA polymerases (Roche) from template DNA plasmid digested by NotI or SpeI (New England Biolabs), and were cleaned by RNeasy mini kit (QIAGEN). We followed the protocol for in situ hybridization described before 35, 41 . We detected fluorescein and DIG probes using TSA plus (Perkin Elmer) green (FP1168) and red (FP1170), respectively.

Section (15 μm) was fixed in 4% PFA at 4 °C for 15 min. Mice stomach tissue were fixed with 4% PFA, and the tissues were rinsed with PBS, 30% sucrose/PBS and embedded in O.C.T compound. Sections (20 μm) were washed with 0.05% Triton x100 (Wako, Cat. #168-11805) in PBS. For ANXA10 immunostaining, the sections were immunostained with anti-Annxin A10 antibody (R&D, Cat. #AF3544, 5 μg/ml) in Canget signal immunostain solution A (TOYOBO, Cat. #NKB-401) for 1 h.

Immunofluoresence microscopy was performed using confocal microscopy (LSM510 META; Carl Zeiss) equipped with a microscope (Axiovert 200 M; Carl Zeiss), a plan Apochromat × 100/1.4 NA oil immersion lens and LSM image Browser software (Carl Zeiss) as described29 (link) with slight modifications. The list of antibodies with source and conditions of indirect immunofluorescence is shown in Supplementary Table 2. In some immunofluorescence experiments, we used Can Get Signal immunostain Solution A (TOYOBO). For induction of primary cilia, RPE1 and IMR-90 cells were seeded on sterile coverslips, grown for 1 day and then subjected to serum starvation. For detection of primary cilia, cells were placed on ice for 20–30 min before fixation with cold methanol, and stained with anti-acetylated tubulin antibody29 (link). BrdU incorporation was evaluated using DNA Replication Assay Kit (Millipore). Quantification of fluorescence intensity was performed using ImageJ 1.45r software.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
