Experimental details: For immunofluorescence analysis, A431 cells were fixed and permeabilized for detection of endogenous TP63 using Anti-TP63 Recombinant Rabbit Monoclonal Antibody (Product # 703809, 1:100 dilution) and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000). Panel a) shows representative cells that were stained for detection and localization of TP63 protein (green), Panel b) is stained for nuclei (blue) using ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). Panel c) represents cytoskeletal F-actin staining using Rhodamine Phalloidin (Product # R415, 1:300). Panel d) is a composite image of Panels a, b and c clearly demonstrating nuclear localization of TP63. Panel e) represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

Experimental details: Knockdown of TP63 was achieved by transfecting A431 cells with specific siRNA (Silencer® select Product # s13309, s13311). Immunofluorescence analysis was performed on A431 cells (untransfected, panel a-d), transfected with TP63 specific siRNA (panel i-l) or non-specific scrambled siRNA (panels e-h). Cells were fixed, permeabilized, and labeled with Anti-TP63 Recombinant Rabbit Monoclonal Antibody (Product # 703809, 1:100 dilution), followed by Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000). Nuclei (blue) were stained using ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962), and Rhodamine Phalloidin (Product # R415, 1:300) was used for cytoskeletal F-actin (red) staining. Significant reduction of the signal was observed upon siRNA mediated knockdown (panel i-l) confirming the specificity of the antibody to TP63 (green). The images were captured at 60X magnification.

Experimental details: Fig. 2. Spatiotemporal cell tracking of NHKc spheroids in 3-D suspension culture. (A) Schematic illustrating 2-D monolayer NHKc cultures transfected with an eGFP reporter plasmid and employed for epidermal spheroid formation assay. (B) Manual image of eGFP-expressing SF-NHKc after 6 h in 3-D suspension culture. (B1) Automated image of eGFP-tagged NHKc suspensions (white dots) at 6 h. (C) Bright phase image of eGFP-expressing keratinocytes within a multicellular spheroid after 24 h in suspension culture. (D) eGFP-labeled cells are seen out of a spheroid after 36 h in suspension culture. (E) Fluorescent tracking of eGFP-labelled cells after 15 days in suspension culture. The proportion of eGFP-expressing cells in each spheroid compartment (i.e. center, edge, or outside) was quantified at distinct time points by ImageJ analysis. (F) Compact ring of cells generated from a single spheroid after 15 days in suspension. White contour lines delineate the outer edge of the spheroid ( o ); orange contour lines delineate the spheroid's center ( c ) from the spheroid's inner edge ( e ). (F1) Dense ring of cells immunostained with DAPI, antibodies against pan-tumor protein 63 targeting all TP63 isoforms (P63, red), and basal cytokeratin 14 (K14, green). Scale bar = 50 muM. (G) Expression levels of mRNAs encoding involucrin in cells within the dense floating ring compared to cells located outside the ring, relative to corresponding monolayer mass cultures as determined by Real-time RT-PCR.

(J) Colony renewal visible by Giemsa staining 20 days after a single spheroid is plated back into 2-D monolayer culture. Black arrows depict the radial migratory patterns of SD cells as they travel from (a') the adherent spheroid to (b'-c') open spaces throughout the dish.

Orange arrow indicates the location of the 2-D attached spheroid. (K) Bright-field microscopic image of an adherent spheroid 15 h after attachment in 2-D culture. (K1) Magnified image depicting epidermal sheets forming underneath the adherent spheroid. (L-L1) Automated imag
