Evaluation of the differentiation potency of the six MSA patient-derived iPSC lines, using two different functional assays that differ in the developmental time: (A) early-stage and (B) late-stage in the induction of all the three embryonic germ layers. (A) Schematic representation of the early-stage method, in which iPSCs were singularized, cultured as a monolayer, and treated with defined differentiation commercial mediums. This protocol is based on the STEMdiff™ Trilineage Differentiation Kit. (B) Schematic representation of the late-stage method, in which embryoid bodies were generated, grown during 2–3 days, transferred in adherent conditions, and treated with defined home-made differentiation mediums. The differentiation potential was established (A) within 1 week or (B) after 4 weeks. (C-E) Representative three-channel immunofluorescence imaging and the corresponding merged obtained using the (A) method and the MSA01 cell line, (C) PAX6 combined with NES as ectoderm markers; (D) SOX17 combined with FOXA2 as endoderm markers; and (E) Brachyury (TBXT) combined with NCAM1 as mesoderm markers. (F) All early ectodermal (PAX6 and NES), (G) endodermal (SOX17 and FOXA2), and (H) mesodermal (TBXT and NCAM1) lineage markers were homogeneously and highly expressed in the six MSA patient-derived iPSC line. (I-K) Equivalently, all late markers were detected. (I) The ectoderm derivative showed cells extending projections and ubiquitously expressing the β-tubulin III (TUBB3) protein. Some of these cells were assembled as neural rosettes. (J) The induction of the endoderm was confirmed by the expression of <t>α-fetoprotein</t> (AFP), revealing a single layered cup-shaped epithelium. (K) For the mesodermal differentiation, cells expressed α-smooth muscle actin (ACTA2), exhibiting the distinctive contractile stress fibrils. Nuclei were counterstained with DAPI in (C-K) . Scale bars (C-K) 20 µm.

The schematic diagram of AFP activating the PI3K/AKT signaling pathway leading to liver cancer cells' tolerance to lenvatinib. AFP activates the PI3K/AKT signaling pathway, stimulating the expression of glucose metabolism reprogramming key enzymes, LDHA, PKM2, HK2 and PFK1 regulated by hypoxia-inducible factor-1α(HIF-1α), and promoting the production of lactic acid in HCC cells. AFP can also promote the expression of P-pg and Bcl-2. Lactic acid, synergizes with P-gp and Bcl-2, inhibits the killing effect of lenvatinib on liver cancer cells
