A schematic diagram of the procedure is described in Figure 4 . Episomal plasmids and methods were described previously15 (link). Plasmid combination #19 (pEP4-E-O2S-E-T2K, pEP4-E-O2S-E-N2K and pCEP4M2L) was used for most reprogramming unless mentioned otherwise. Plasmids and EBNA mRNA were electroporated into fibroblast cells on Amaxa apparatus according to company instructions. One million cells were used in each electroporation, which were then plated into two 6-well plates. E8 + hydrocortisone media were used for the first 5–10 days, according to cell survival and proliferation after electroporation. When confluency was reached ~20%, hydrocortisone was removed. ES-like iPS cell colonies usually appear after ~25 days. Cells were then picked into individual wells with E8 (TGFβ or NODAL). Cells were passaged for ~ 15 passages before subcloning with Y27632 on Matrigel or vitronectin.

Tumor pieces will be dissociated enzymatically and mechanically to obtain isolated cells or small cell clusters (Fig. 2 ). Cells will be embedded in an extracellular matrix (growth factor-reduced Matrigel or BME II) and cultured in a medium supplemented with growth factors and signal pathway inhibitors [Advanced DMEM (Gibco) supplemented with 100 UI/mL of penicillin and streptomycin (Gibco), 1% GlutaMAX (Gibco), 1X B27 (Gibco), 1.25 mM NAC (Sigma-Aldrich), 50 ng/mL EGF (PeproTech), 10 ng/mL FGF-10 (PeproTech), 5 ng/mL FGF-b (PeproTech), 500 nM A-83-01 (PeproTech), 10 μM Y27632 (Interchim), 10 mM Nicotinamide (Sigma-Aldrich), 1 μM PGE2 (PeproTech), 1 μM Forskolin (Peprotech), 0.3 μM CHIR99021 (Biogems), 100 μg/mL Primocin (InvivoGen), 50% Wnt3a, RSPO3, Noggin-conditioned media (L-WRN, ATCC), and 10% RSPO1-conditioned media (Cultrex HA-R-Spondin-1-Fc 293 T, Amsbio)]. Culture medium will be changed twice a week. Once formed, PDTO will be dissociated and reseeded to amplify them for experimental purposes. Cryovials will be prepared at regular intervals by dissociating and resuspending PDTO in Recovery Cell Culture Freezing Medium (Gibco) prior to be biobanked in liquid nitrogen. It should be noted that PDTO line will be considered as established when it will be maintained for more than 3 passages. For each PDTO line, samples will be kept frozen for DNA/RNA/protein analysis and others will be embedded in paraffin for histopathological analysis. This will allow comparisons between the characteristics of the PDTO and the tumor from which they are derived in order to validate their correspondence.![]()

The evaluation of the response to treatments will be performed when PDTO have reached a diameter of 150 μm in « PDTO treatment medium », corresponding to the PDTO culture medium lacking N-Acetylcysteine, Y-27632 and primocin.
PDTO will be collected, resuspended in 2% extracellular matrix/PDTO culture medium and then platted in white and clear bottom 96-well plates previously coated with a 1:1 volume mix of PDTO treatment medium with extracellular matrix. In the case of evaluation of the response to radiotherapy, PDTO will be before irradiated using the CellRad System (FAXITRON Bioptics). In the case of evaluation of the response to chemotherapy or PARP inhibitors, drugs are prepared in 2% extracellular matrix/PDTO culture medium and added 1 hour after PDTO have been plated.
In the case of evaluation of the response to immunotherapies, PDTO will be co-cultured with PDTO specific T cells previously generated (see co-culture of PDTO with immune cells) at a 5:1 ratio. Treatments (such as Nivolumab or Pembrolizumab) will be added directly in the co-culture. A condition containing an MHC-I blocking antibody will be added to control for antigen specific killing.
PDTO morphology will be monitored by taking images during the required time using Incucyte S3 (Sartorius). At the endpoint, PDTO response will be assessed using CellTiter-Glo 3D cell viability assay (Promega) according to the manufacturer’s instruction and luminescence will be measured using GloMax Discover GM3000 (Promega) with the associated software. Results will be normalized to the control condition. IC50 will be calculated with GraphPad software. The ability of T cells to recognize and induce lysis of PDTO will be monitored via analysis of caspase 3 cleavage within PDTO and visualization of LAMP-1 on the membrane of CD8+ T cells.
The treatment response of the PDTO will be finally compared to the clinical response (PFS/DFS/OS) of the patient from whom they are derived in order to validate the predictive value of this model for HNSCC.

IPSc-derived cardiomyocytes were cultured on glass slides coated with Synthemax II-SC (Corning) in RPMI-1640/B-27 with Y27632 (5 μM) media for 2 days. Cells were fixed with 4% formaldehyde for 15 min at room temperature. Fixed cells were blocked in antibody buffer (5% BSA, 0.1% Tween-20 in PBS) for 1 h at room temperature. Following blocking, cells were incubated overnight at 4 °C with cardiac troponin-T antibody (abcam, ab45932, 1:200), α-Actinin antibody (Sigma, A7811, 1:800), and/or Connexin 43 (Cell Signaling Technology, 1:100) in antibody buffer. After the overnight incubation, cells were washed three times in antibody buffer. Following washing, cells were incubated with Alexa-Fluor conjugated secondary antibodies (Thermo Fisher Scientific, Alexa 488 Donkey anti-Rabbit IgG and Alexa 594 Goat anti-Ms IgG1) at a 1:1,000 dilution in antibody buffer for 1 h at room temperature. Nuclei were stained by DAPI at 1 μg/ml and Wheat Germ Agglutinin (Thermo Fisher Scientific, W21404) was used to stain cell membrane for 10 min at room temperature in antibody buffer. Following washing in PBS to remove unbound complexes, sarcomeres were analyzed using a Zeiss LSM510 confocal microscope. Images were processed with Zeiss software (Axiovision Rel4.8 and Zen Blue). Circularity measurements were made by comparing cardiomyocyte length to width and were expressed as a circularity index whereby circularity index = width/length15 (link). Sarcomere distance measurements were made with ImageJ15 (link). All measurements were made with a double-blinding method.
