Cancer is a major global health issue;in 2020,there were 19.29 million new cancer cases and 9.96 million cancer deaths worldwide(Siegel et al.,2023).Despite ongoing research,chemotherapy remains the primary treatment due to its broad anti-cancer effects(Marra and Curigliano,2021).However,intravenous chemotherapeutic drugs commonly induce hematotoxicity,necessitating dose adjustments or treatment ***-induced thrombocytopenia(CIT)and neutropenia(CIN)are the primary manifestations of chemotherapy-induced hematotoxicity,which requires intervention due to the heightened risk of bleeding and infection(Blayney and Schwartzberg,2022).Currently,there are no FDA-approved treatments for CIT(Song and Al-Samkari,2023).While a CIT mouse model using 5-FU has been developed for drug evaluation(Shin et al.,2023),it lacks a comprehensive hematotoxicity assessment and the benefits of high throughput,cost-effectiveness,and ***,it is urgent to develop a high-throughput CIT model for risk assessment and safer chemotherapy strategies with clinical potential.

Placental site trophoblastic tumor(PSTT),a rare gestational trophoblastic neoplasm(GTN),exhibits slow growth,late-onset metastasis,and chemotherapy insensitivity[1,2].The invasive capacity of trophoblasts induces angiogenesis in PSTT,yet the specific mechanism remains unclear[3].PSTT is typically resistant to chemotherapy and hysterectomy stands as the primary therapeutic choice for patients with an overall cure rate of approximately 75%-80%[4,5].Therefore,investigating the precise emergence and progression of PSTT is crucial,aiming to identify novel targets for diagnosis and therapy.
