Figure Lengend Snippet: Summary of the results obtained on 2nd-generation spheroids derived from primary TNBC cell line MS-186, disaggregated from 1st-generation spheroids after STD or mCHT treatments. In the absence of treatment (NT), CSCs continue to proliferate and maintain stemness markers (CD44, CD133, MYC, cleaved NOTCH-1), epigenetic regulators (H3K27ac, EZH2), and signaling molecules (p-STAT3/STAT3). The STD treatment partly reduces the mass and the number of spheroids but induces high levels of stemness markers, which continue to activate stemness pathways and sustain drug resistance. In contrast, mCHT dramatically impairs spheroid formation, epigenetic signaling, and associated markers, thereby improving treatment responses.
