Research overview

In order to further improve the efficacy of chemotherapy on OS, here we developed a senolytic drug delivery system based on engineered Natural killer (NK) cell-derived extracellular vesicles (EVs) that can target OS cells. Treatment-induced senescence (TIS) can lead to incomplete tumour clearance and potential recurrence.

Key findings

Osteosarcoma (OS) is a type of bone tumour characterized by high risk of metastatic progression and recurrence after therapy.

Traditional tumour treatment methods such as radiotherapy and chemotherapy can lead to the accumulation of senescent cells in tumours.

Treatment-induced senescence (TIS) can lead to incomplete tumour clearance and potential recurrence.

Recently, the combination of chemotherapy drugs and senolytics drugs ('one-two punch' therapy) has become a promising strategy for improved tumour treatment, but this method also faces challenges in terms of safety and targeting specificity.
