MKI67 and neoplasm: As shown in the Fig. 6g and Supplementary Fig. 20, the NIL-IM-Lip+L group showed more nuclear shrinkage by H&E staining, fewer Ki67-positive cells, and more TUNEL-positive cells, which indicated that NIL-IM-Lip+L could effectively inhibit the proliferation and enhance the apoptosis of tumour cells.
