Fig. 2From: MAL gene overexpression as a marker of high-grade serous ovarian carcinoma stem-like cells that predicts chemoresistance and poor prognosisImages of PKH-26 staining during spheroid formation (magnification 100X). Single cells labeled with PKH-26, derived from mechanic dissociation of OVA-BS4 spheroids; day 0 (a). After 4Â days, most of the cells underwent PKH-26 dilution in the newly formed spheroids while few retained the red label (b)Back to article page
