Figure Lengend Snippet: Images of A-431 epidermoid carcinoma cells seeded over a layer of 10% HPMC gel at 24 h after seeding ( a ) and further visualized at 5 days after gel removal and cultivation of cells in 3D culture medium ( b ). Images were taken with an EVOS 200 inverted microscope. ( c ) Images of HaCaT keratinocytes seeded over a layer of 10% HPMC gel, visualized at 24 h after seeding with an EVOS 200 inverted microscope.
Article Snippet: For obtaining tumorspheres, 3D culture medium (3D Tumosphere Medium XF medium, PromoCell, Heidelberg, Germany) supplemented with 1% antibiotic–antimycotic solution (Sigma, Burlington, MA, USA) was used alone or in combination with HPMC.
