Methods of salivary gland organoid culture have been previously described (Yoshimoto et al., 2020 (link)). This study was performed with the permission of the ethics committee in Fukuoka Dental College (number 406). Salivary glands were obtained from the patients with mucous cysts or head and neck tumors who underwent an operation in Fukuoka Dental College hospital. Human squamous cell carcinoma cell line, HSC-4, was purchased from JCRB cell bank (Osaka, Japan). Spheroid culture was previously described (Yoshimoto et al., 2022 (link), 2023 (link)). Briefly, 1×104 cells in 200 μl Dulbecco's Modified Eagle's Medium (DMEM, Sigma-Aldrich, St. Loius, MO, USA) with 10% FBS were seeded in each well of 96-well Nunclon Sphera plate (Thermo Fisher Scientific, Waltham, MA, USA). 10% neutral buffered formalin or 4% paraformaldehyde -fixed and paraffin-embedded organoids tissue blocks were cut into 4-μm-thick sections and mounted on adhesive glass slides (CRE-01, Matsunami Glass, Osaka, Japan) for HE and immunohistochemical staining. Frozen sections were prepared by embedding samples in Tissue-Tek optimal-cutting-temperature (OCT) compound (Sakura Finetek Japan, Tokyo, Japan) and cryosectioning. The images of HE and immunohistochemical staining were captured using an AXIO Vert.A1 microscope (Carl Zeiss, Oberkochen, Germany).

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.
