Abstract A myriad of biological effects can be stimulated by the ultrasound (US) for treatment cancer. The objective our research was to investigate effect alone and in combination with chemotherapeutic drugs such as doxorubicin (DOX) temozolomide (TMZ) on human glioblastoma (GBM) epidermoid carcinoma cancer 2D 3D cell cultures. Results indicated that US 96-probe device could induce tumour sphere cytotoxicity a dosage- time-dependent manner, multiple treatments augmenting this cytotoxic effect. With enhanced cytotoxicity, decreased growth metabolic activity, disrupted spheroid integrity, heightened occurrence DNA double strand breaks, resulting damage spheres an inability rebuild after treatments. TMZ / DOX efficiency GBM enhancing induced compared monolayer cells, also increasing incubation time, which is most crucial way differentiate between effectiveness drug without US. In conclusion, data demonstrate enhances diffusion, uptake, using models when It demonstrates significance culture delivery discovery research. Graphical

Cancer stem cells (CSCs) are considered to be responsible for recurrence, metastasis, and resistance treatment in many types of cancers; therefore, new strategies targeting CSCs attracting attention. In this study, we fabricated a polyethylene glycol-tagged microwell device that enabled spheroid formation from human oral squamous carcinoma cells. HSC-3 Ca9-22 cultured the aggregated generated single per well within 24–48 h. The circular shape smooth surface spheroids were maintained up five days, most comprising Calcein AM-positive viable Interestingly, mRNA expression CSC markers (Cd44, Oct4, Nanog, Sox2) significantly higher than monolayer cultures. marker-positive observed throughout spheroids. Moreover, cisplatin was enhanced spheroid-cultured compared monolayer-cultured Furthermore, some marker genes upregulated outgrown xenograft model, tumor growth implantation group comparable culture group. These results suggest our system may high-throughput tool producing uniform large numbers cancer
