Adriamycin (ADR) resistance poses a significant challenge for successfully treating breast cancer (BCa). The mechanism underlying intrinsically acquisition of the resistance remains to be fully elucidated. Here, we describe that small extracellular vesicles (sEVs) mediated Hsp70 transfer is implicated in ADR resistance. The resistant cells derived sEVs were incubated with sensitive cells, thereby transmitting the resistant phenotype to the recipient cells. The internalization of the sEVs in the recipient cells and sEV-mediated Hsp70 t
