Analysis of the proliferative activity of salivary gland and liver progenitor cells under 2D and 3D cultivation conditions, 1st passage, fluorescent microscopy. Cell nuclei stained by DAPI (blue color), BrdU stained by Alexa Fluor 488 (green color), bar is equal to 100 µm. A) PSGC, 2D conditions; B) PSGC isolated from the collagen gel after cultivation for 10 days under 3D conditions; C) PSGC, 10 ^th day of cultivation in the collagen gel (without isolation); D) PLPC, 2D conditions; E) PLPC isolated from the collagen gel after cultivation for 10 days under 3D conditions; F) PLPC, 10 ^th day of cultivation in the collagen gel (without isolation)
