Figure Lengend Snippet: ( A ) An illustrative representation of a cross-section of the skin, indicating the layers (epidermis and dermis) that were resembled by the 3D hybrid hydrogel, depicted with information regarding its components, chemical formula, and structure. ( B ) Scheme of the co-culture strategy of the cell therapy product simulating the skin layers, with the deposition of keratinocytes in the membrane layer (resembling basement membrane of skin) and populating the porous layer with fibroblasts to obtain a cellular biomimetic dermal–epidermal skin substitute construct (not to scale).

Article Snippet: For keratinocytes, Gold Keratinocyte Growth Basal Medium supplemented with a KGM-Gold TM Keratinocyte Single Quots TM Kit (Lonza, Morristown, NJ, USA), referred to as “complete basal keratinocyte medium”, was used.

Techniques: Co-Culture Assay, Membrane, Construct

Figure Lengend Snippet: ( A ) Results of cell viability (MTT cytotoxicity test) and ( B ) cell proliferation (measured using resazurin protocol) biological assays for the porous three-dimensional structures (3d = 3 days). ( C ) Calcein AM (viable cells, green fluorescence, left side images, identified as LIVE) and ethidium homodimer (dead cells, red fluorescence, right side images, identified as DEAD) staining for keratinocyte and fibroblast monoculture cells deposited onto the lower and upper faces of the L-arginine functionalized 3D constructs, respectively (scale bar = 100 µm). Details: schematic representation of cell deposition (not to scale).

Figure Lengend Snippet: Fluorescence microscopy images showing representative images of the 3D CMC:PVA:CHI_L-Arg structure, where a co-culture of ( C ) keratinocytes (upper face—membrane) and ( D , E ) fibroblasts (lower face—porous structure) were seeded compared to controls (( A ) Keratinocyte +Control and ( B ) Fibroblast +Control). Cells were labeled with calcein AM (viable cells, green fluorescence, left column, identified as LIVE) and ethidium homodimer (dead cells, red fluorescence, right column, identified as DEAD). Scale bar = 100 µm. Detail: schematic representation of cell therapy dermal–epidermal skin substitute (not to scale).

Figure Lengend Snippet: Histopathological analysis of skin lesions in Hairless mice, showing representative images of ( A ) skin from the control group (no hydrogel applied) and ( B ) skin from the group treated with the 3D bilayer construct containing fibroblasts and keratinocytes (CM group). Black asterisk: intact epidermis; red asterisk: denser collagen; green asterisk: looser collagen; black arrow: reactive fibroblasts; red arrow: blood capillaries. The larger image displays the lesion area at 20× magnification, with a zoomed-in view of the highlighted area at 40× magnification.
